Pale Moon (64-bit)

What's new in this version:

- Fixed a major performance issue with web workers
- Fixed a rare crash on local networks with HTTP basic auth and unsupported cipher suites
- Fixed a performance/timer issue when leaving the browser idle
- Fixed an issue causing an empty dialog when launching executable files from the browser
- Fixed an issue preventing making entries to disallow sites to store data for off-line use
- Removed code to prevent extensions with binary components
- Fixed an issue with common dialogs being sized incorrectly for their content
- Fixed an issue with event handling on the tab bar that would cause frustrating behavior when trying to open/close tabs in rapid succession
- Switched default behavior for scrolling when a context or pop-up menu is open to allow scrolling, like in v27. This also affects scrolling in very long menus, e.g. bookmarks
- Added experimental Asynchronous Panning and Zooming (APZ) for desktop use
- Re-enabled the use and parsing of ICC v4 color profiles
- Removed telemetry code from the caching subsystem
- Improved full-screen detection for suppressing status messages
- Made all arguments passed to Init*Event() optional except the first for parity with other browsers
- Cleaned up some internal installer code
- Fixed making caret width configurable when dealing with CJK characters (regression)
- Fixed drawing of table borders consistently when zooming a page (regression)
- Exposed the "Save download location per site" pref in about:config
- Improved media handling (ongoing)
- Added experimental support for AV1 in WebM videos (disabled by default)
- Note: this is for WebM only for now, so MP4 and MSE AV1 streams (e.g. YouTube) will not (yet) play
- Removed the (defunct and incomplete) in-browser translation code
- Fixed an issue with CSS Grid layouts unnecessarily shrinking element blocks
- Fixed notification settings menu entry (opes about:permissions with relevant data now)
- Fixed the launching of an undesirable background content process for capturing page thumbnails
- Fixed a focus issue in the bookmark properties dialog
- Changed the setting for reporting CSS errors to the console to false by default, to prevent unnecessary performance loss for recording this data
- Added control mechanisms for Opportunistic Encryption (both for alternative services and upgrade-insecure-requests) in preferences, and disabled this by default due to potential security and privacy issues with this transitional technology
- Updated the default reported Firefox version in Firefox Compatibility Mode to prevent "too old Firefox" complaints on websites
- Updated libnestegg, ffvpx, reader view components and several other modules from upstream
- Implemented security fixes for CVE-2018-12381, CVE-2017-7797, a better fix for CVE-2018-12386 (DiD), CVE-2018-12401 (DiD), CVE-2018-12398, CVE-2018-12392, several Skia bugs, and several crashes and memory safety hazards that do not have a CVE number
