What's new in this version:

Basilisk Browser 2023.11.05 (64-bit)
- Added an initial implementation of the ReadableStreams API, improving web compatibility with sites that apparently use this API in utilitarian fashion
- Added support for transparency in WebM videos for the edge case of using <video> elements for transparent animated images. Major caveat: this will massively impact performance of video playback if an alpha channel is present in the video
- Added support for crypto.randomUUID to allow website scripting to generate random UUIDs (universally unique identifiers) through the WebCrypto interface
- Removed the user-agent override for Netflix, since they have stopped supporting the Silverlight browser plugin. Basilisk no longer has a way to provide Netflix DRM-controlled playback with them dropping it, so there is no longer a reason to try and force compatibility
- Updated the user-agent override for Spotify. While it is possible to use the website with this, it suffers from the same DRM issue and not all media will be playable (only non-encumbered media can be played in Basilisk like podcasts). Your mileage may vary
- Implemented timer nesting and clamping for workers, preventing timer hangs on bad website code
- Improved handling of drawing SVG images on canvases without explicit width or height attributes. We now follow the css-sizing-3 Intrinsic Sizes spec
- Improved performance of our memory allocator
- Updated libvpx to 1.6.1
- Cleaned up and updated some media playback code
- Removed the last vestiges of EME/DRM code from UXP, since this will never be supported in any application building on it due to the media industry's draconic policies around FOSS
- Removed support for DRM from Basilisk as a followup to the EME/DRM removal in UXP
- Removed simd.js, moving actually used SIMD handling to C++
- Removed the use of libav in our source, replacing its supply of FFT with the equivalent from FFMpeg
- Fixed potential type confusion in IonMonkey due to 3-byte opcodes
- Fixed an issue with tooltips persisting even if the browser window would have lost focus
- Fixed PerformanceObserver navigation and resource timing (default disabled for privacy); our implementation now fully passes conformance tests
- Fixed an issue where top-level SVG images would not be correctly clipped by positioned elements, giving the impression of wrong z-ordering as the SVG would overlap other elements
- Dev: Updated setInterval to fall back to 0 if no duration is supplied
- Dev: Updated ResizeObserver to a recent spec change, now returning an array of results for borderBoxSize and contentBoxSize instead of an object
- Dev: Updated Intl.NumberFormat and DefaultNumberOption() to follow spec updates. Most importantly for web compatibility, we now allow the "maximumFractionDigits" option in Intl.NumberFormat to be less than the default minimum fraction digits for the chosen locale, following the general consensus in TC39 around this issue
- Increased leniency (removed upper limit) of GLSL versions as they tend to be fully backwards compatible
- Fixed various crashes
- Added a safeguard to the sec-gpc header (Global Privacy Control) so it cannot be inadvertently overwritten
- Removed the 360 Secure Browser profile migrator from Basilisk
- WebRTC Spec Improvements
- Add ability toggle WebRTC and WebAssembly under Tools->Preferences->Content
- Enable PerformanceObserver by default in Basilisk
and several other issues without a CVE number assigned to them
- UXP Mozilla security patch summary: 6 fixed, 2 DiD, 19 not applicable

Basilisk Browser 2023.09.15 (64-bit)
- Fixed a WebP decoder issue
- Rebase our PDF.js version on files from the Seamonkey PDF.js addon as well as files ported from Firefox 60.9.0. This upgrades our PDF.js version to 2.3.235, which pulls in almost 3 years of security updates and bugfixes.
- Following the discussion in this forum post, we've introduced GTK2 builds of Basilisk for Linux

- UXP Mozilla security patch summary: 1 fixed, 3 DiD, 17 not applicable

Implementation notes:
- The BigInt primitive (base number format) in JavaScript allows JavaScript to handle excessively large integers (whole numbers). This primitive is especially useful for specialized scientific applications that need very large yet accurate numbers, but has seen widespread adoption for an as of yet unknown reason as part of web frameworks, causing general web compatibility issues for Basilisk when scripts expect BigInt support and instead have an error thrown. We have now implemented this primitive for use so we no longer have compatibility issues with these frameworks. It is still unknown why BigInt is in use there and for what. Critical note: BigInt might be tempting to consider for JS-backed cryptography but this is very ill-advised, as BigInt operations are, by their nature, not constant-time and allow timing and side-channel attacks.
- Flex and grid item sizes in percentages would previously be resolved against the parent like other elements, according to a very long-standing practice that stems from the Internet Explorer days. Mainstream browsers have, however, made an exception for flex items and grid items to no longer do this. We have now made the same exception for these types of elements which should solve layout issues on some websites (notably reserving too much space for items, often resulting in very large areas of whitespace or items being pushed out of view).
- Two preferences were added (layout.css.animation.enabled and layout.css.transition.enabled) to allow users to completely disable CSS-based animations and transition effects. This was a request by users as both a performance and accessibility consideration. Please note that in some cases, disabling animations and transitions may have an impact on final web page layout, so you may run into some issues when disabling these animations and transitions as the web pages were designed to use them.


Basilisk Browser 2023.07.18 (64-bit)
- This is a major development update, further improving web compatibility
- Added the (hidden) preference browser.history.menuMaxResults to allow users to control how many history entries are listed in the menu. Setting this to 0 will hide history menu entries altogether, and any positive number configures how many entries the entries are limited to. The default if not defined is 15.
Switched C++ language level used to C++14 on all platforms.

Web compatibility and scripting improvements:
- Implemented geometry .from* static constructors for web compatibility
- Implemented partial support for CSS calc() in color keywords
- Implemented Array "find from last" feature (findLast and findLastIndex)
- Implemented Object.hasOwn(object,property)
- Implemented several additional Intl API methods and functions. This improves web compatibility with sites making use of things like hourCycle, advanced DateTimeFormat, Intl.Locale, and Intl as a constructor.

- Cleaned up some unused code
- Removed support for Mozilla "experiment" type extensions
- Improved the JavaScript garbage collector's sweeping. This should fix a few intermittent crashes and improve performance
- Implemented some structural changes to the source to make future porting easier, and preparing for switching to C++17
- Removed handling of symlinks for directory listings to prevent potential security issues by walking symlinks when uploading. This effectively reverts a change made in Firefox 50 where this functionality was introduced. A case of "Not such a good idea after all" ;-
- Updated the list of extensions on Windows treated as "executable"
- Security issues addressed: CVE-2023-37208
- Made preparations for requiring Authorization in CORS ACAH preflight
- Since no browser honors this part of the spec at the moment this is left disabled until there is consensus among browsers
- Fixed intermittent crashes related to the performance API
- Fixed intermittent issues with JavaScript malfunctioning in chrome scripts (causing faults in the UI and extensions)
- Added ability to specify build version in mozconfig when compiling Basilisk
- UXP Mozilla security patch summary: 2 fixed, 2 rejected, 20 not applicable

- Security issues addressed: CVE-2023-32209, CVE-2023-32214 and several others that do not have a CVE designation
- UXP Mozilla security patch summary: 4 fixed, 1 rejected, 27 not applicable

Implementation notes:
- JavaScript modules have various methods of being loaded into web page content. One of the later introduced methods is a function-style import() declaration, so-called "dynamic module imports" that has been used by various web frameworks, causing issues for Basilisk resulting in blank pages in most cases (since the websites would not actually use document structure HTML, but rather JavaScript to create content, all from imported modules). This has been a major web compatibility issue lately and we're pleased to announce that this complex bit of machinery has been implemented.
- JavaScript's language specification is continuing to be watered down from a prototyping language towards a more "C-like" hybrid. As part of that effort, JavaScript classes were introduced in ECMAScript 6, and now further expanded in ES2022 with class fields and private class fields/methods, as well as statics. We should have a complete implementation of this now, which constitutes the more important parts of the ES2022 language update.
- The use of the outdated Microsoft Internet Explorer global window.event has been a pervasive web compatibility issue for us, especially since it was officially deprecated and we never implemented this ambiguous and unreliable property that is highly-context sensitive. Websites should use the event as passed into the event handler to get the event source instead. However, since neither Chrome nor Firefox have dropped this and seem to be playing a game of "chicken", it remains in use on the web. To deal with this conflict, we have now implemented the equivalent behind a preference to enable users to (temporarily) use the global window.event while webmasters update their websites. We hope the Google camp will finally drop this one soon so we can be done with this legacy quirk.

The DOM Performance API was updated to the User Timing level 3 spec. It should be critically noted that the DOM Performance API was never designed to be used as a matter of course on published content, and was designed only for page performance analysis use by web designers. Of course, as part of making dev tools available to the web, a lot of abuse ensued because of the accurate navigation and timing measurements that this API can provide (looking at you, Google!). Because of tight integration with web content analysis, the older spec implementation we had was causing issues and actually breaking some services, so we updated it, but with a few important key differences:
- In Basilisk, we keep navigation timing disabled because it's a notable privacy issue for the data it can gather (exact navigational events and timings). If you're a web dev and need these timing measurements, you can enable them with dom.enable_performance_navigation_timing.
- Our implementation, contrary to the spec, does not allow unlimited recording of performance events (effectively logging every page event!) which can also rapidly eat up memory. Instead we enforce a sane default quota that should be roomy enough for all legitimate use, but prevents runaway resource use or extensive logging of user actions.
- If the set quota is reached, a warning will be printed in the console and the recorded performance events will be thrown away. If you (foolishly) rely on Performance API events for your web application to function, be aware this may cause compatibility issues as the API was, again, not designed to be used in such a fashion. For event handling, there are much better alternatives available which do not involve extensive recording of user data or relying on a developer tool API.

- We've historically implemented the DOM getRootNode function as it was being used in the wild as a standalone function, however its main intent has always been to be a helper function part of Shadow DOM/WebComponents. As such we have now merged the preference into the WebComponents preference, enabling and disabling it along with the rest of our WebComponents implementation.


Basilisk Browser 2023.05.01 (64-bit)
- This is a bugfix and security release
- Note: macOS, Linux aarch64, and FreeBSD beta builds will identify as 2023.04.30
- Fixed a crash in CompareDocumentPosition with Shadow DOM
- Fixed a crash with display:contents styling
- Added a preference to disable the TLS 1.3 protocol downgrade sentinel (see implementation notes)
- Changed the way large clipboard copy/paste operations are handled, improving privacy (see implementation notes)
- Improved filename safety when saving files to prevent potential environment leaks (bis).
- Improved sanity checks of MIME type headers
- UXP Mozilla security patch summary: 2 fixed, 1 rejected, 49 not applicable

Implementation notes:
- Some proxies and middleware boxes improperly handle the TLS 1.3 protocol handshake causing an insecure downgrade to TLS 1.2. With our recent update of NSS, Basilisk no longer allows this kind of protocol downgrade when trying to establish a TLS 1.3 connection to a server. The resulting error is ssl_error_rx_malformed_server_hello with an inability to connect to the server. To enable users to still connect to the servers or devices in question, we've added an option to switch off the downgrade sentinel. To switch it off as a temporary workaround, set security.tls.hello_downgrade_check to false.
- If copy and paste operations to/from the browser are performed, Basilisk writes clipboard contents to disk in a temporary cache file if the copy/paste amount is particularly large, to avoid using large amounts of memory to hold this data. The average paste/clipboard size doesn't tend to hit this limit in which case it is just held in memory.
- Previously, these cache files, while in the O.S. temporary file location (%TEMP% or /tmp), would not be consistently cleaned up, potentially causing privacy issues if persisted. This was changed to using auto-cleaning anonymous temp files, improving user privacy and relying less on the O.S. or user performing cleanup of temporary file storage. Thanks to Sandra for pointing this out and providing the patch.


Basilisk Browser 2023.04.04 (64-bit)
This is a major update which introduces WebComponents support among other things:
- Basilisk is now available in beta for macOS and FreeBSD
- Shadow DOM and CustomElements, collectively making up WebComponents, have been enabled by default which should bring much broader web compatibility to the browser for many a site that uses web 2.0+ frameworks. See implementation notes.
- Tab titles in the browser now fade if they are too long instead of using ellipses, to provide a little more readable space to page titles. Note that this may require some updates to tab extensions or themes.
- A number of site-specific overrides have been updated or removed because they are no longer necessary or current with the platform developments in terms of web compatibility. We could use your help evaluating the ones that are still there; see the issue on the Pale Moon repo.

- UXP Mozilla security patch summary: 4 fixed, 2 DiD, 19 not applicable


Basilisk Browser 2023.01.07 (64-bit)
This is a major development, bugfix and security release:
- Added support for the JPEG-XL image format
- Implemented regular expressions lookaround/lookbehind
- Aligned CORS header parsing with the updated spec. See implementation notes
- We no longer fire keypress events for non-printable keys. See implementation notes
- Added support for MacOS 13 "Ventura" in the platform, primarily benefitting White Star

- Added some extra sanity checks to our zip/jar/xpi reader to avoid issues with corrupt archives
- Aligned cookie checks with RFC 6265 bis. See implementation notes
- Removed obsolete code in Windows widgets that could cause potential issues with long paths and file names on supported versions
- Fixed several crashes
- Security issues addressed: CVE-2022-45411, CVE-2022-46876, CVE-2022-46874 and several others that do not have a CVE numbe
- UXP Mozilla security patch summary: 6 fixed, 1 DiD, 1 deferred, 45 not applicable

Implementation notes:
- RFC 6265 has been worked on with draft changes describing how cookies are actually being handled in the real world, in the bis versions of the RFC. While these changes have not yet been finalized, browsers in general do adhere to the latest available bis version of this RFC. Specifically, the long-standing exceptions for cookie names and values have been formalized, e.g. having quoted values. Our behavior has changed in that we now once again accept Tab characters (0x09) which is the one excluded control character from the range that is otherwise forbidden. We also no longer apply these checks exclusively to those in http headers, and any way of setting cookies must now adhere to the valid range. Cookies that fail these range checks for valid characters will be ignored.
- CORS support has been updated to the current spec. Most importantly, Basilisk now accepts wildcard entries ("*") for the CORS statements Access-Control-Expose-Headers, Access-Control-Allow-Headers and Access-Control-Allow-Method. Note that wildcards are ignored (according to the spec) when credentials are passed.
- Basilisk will no longer fire the keypress events in content when the key pressed is a non-printable key. This is in response to issues where webmasters would use rudimentary and naïve input-restricting scripts in onkeypress handlers that would not take into account editing keys or navigation keys, causing issues for users trying to enter data into forms (and e.g. finding they could no longer use backspace, cursor keys or tab). This aligns our behavior with other browsers for web compatibility, although it should be considered a website error expecting not all keypresses to be intercepted in keypress events.


Basilisk Browser 2022.11.04 (64-bit)
Fixed:
- a potential heap Use-After-Free risk in Expat

Basilisk Browser 2022.08.06 (64-bit)
This is a major update:
- Very Important: This is the first public release from the Basilisk Development team. As such, the vendor name in the application has changed. This means the profile directory has changed. See here for more info. You will have to perform a manual update if you are currently running Basilisk 2022.01.27 as it was compiled without an updater.
Note: Many things have changed since 2022.01.27 and 2022.08.06. We've tried to note all changes here but it is very likely something was missed:
- Fixed several application crash scenarios
- Fixed a number of thread locking/mutex issues
- Fixed a leak of content types due to inconsistent error reporting
- Fixed an issue with iframe sandboxing not being properly applied
- Fixed a potential leak of bookmarks from the exported bookmarks file if it included a malicious bookmarklet.
- Fixed an issue with drag-and-drop
- Fixed a potential crash due to truncated WAV files.
- Fixed a memory safety issue with XSLT
- Fixed a potential crash issue on bing.com.
- Fixed some thread locking issues
- Worked around a Mesa driver bug that could cause crashes
- Fixed a potential resource access issue in devtools
- Security issues with CVEs addressed: CVE-2022-1097, CVE-2022-28285 (DiD) and CVE-2022-28283 (DiD).
- Implemented Global Privacy Control, taking the place of the unenforceable "DNT" (Do Not Track) signal. Through GPC, you indicate to websites that you do not want them to share or sell your data.
- Implemented "optional chaining"
- Implemented setBaseAndExtent for text selections
- Implemented queueMicroTask() "pseudo-promise" callbacks

- Improved performance of parallel web workers in JavaScript
- Improved display of cursive scripts (on Windows). Good-bye Comic Sans!
- Updated various in-tree libraries
- Added support for extended VPx codec strings in media delivery via MSE (RFC-6381).
- Fixed a long-time regression where the browser would no longer honor old-style body and iframe body margins when indicated in the HTML tags directly instead of CSS. This improves compatibility with particularly old and/or archived websites.
- Fixed several crashes and stability issues
- Removed all Google SafeBrowsing/URLClassifier service code
- Restored Mac OS X code and buildability in the platform
- Removed the non-standard ArchiveReader DOM API that was only ever a prototype implementation
- Removed most of the last vestiges of the invasive Mozilla Telemetry code from the platform. This potentially improves performance on some systems.
- Removed leftover Electrolysis controls that could sometimes trick parts of the browser into starting in a (very broken) multi-process mode due to some plumbing for it still being present, if users would try to force the issue with preferences. Obviously, this was a footgun for power users.
- Removed more Android/Fennec code (on-going effort to clean up our code).
- Removed the Marionette automated testing framework.
