Pale Moon (64-bit)

What's new in this version:

Changes/fixes:
- Dropped support for Direct2D 1.0 to avoid font rendering issues. Windows installations not capable of using Direct2D 1.1 will now fall back to software rendering. As a result, fonts may look different from this version onwards if you are on Windows Vista or Windows 7. Users on Windows 7 affected by this should install the Platform Update to re-enable Direct2D
- Updated the Brotli decoder library, and enabled support for Brotli HTTP content-encoding by default
- Added notifications to inform users about WebExtensions not being supported if they try to install them (as opposed to "extension is corrupt")
- Added a number of DOM childNode convenience functions. This should fix some lazy-loading frameworks
- (enjoy your LOLcats again!)
- Changed automatic updates over to the new infrastructure
- Added extra proxy settings in Options, covering DNS lookups through SOCKS v5 and automatic proxy authentication with known credentials
- Added a selectable fallback character encoding of UTF-8 and fallback to UTF-8 as a last effort. (Issue #1423)
- Improved timing of canplay and canplaythrough firing to work around a potential race condition locking up queued video playback
- Improved upmixing of mono sound for multi-channel setups
- Fixed a parallelization issue with the KISS-FFT library causing CPU-deadlocked threads (Issue #1425)
- Fixed "Remove from history" function from the downloads panel
- Forced focus on the address bar in new windows if the content is a blank/empty document
- Fixed the dropmarker in the address bar to allow the suggestions to be closed with a click
- Further cleaned up the status bar code
- Disabled window.showModalDialog; it's been removed from the spec 2 years ago and has potential abuse issues (modal dialogs block the UI)
- Fixed image decoder calls to make sure the image load event doesn't fire prematurely
- Updated LibPNG to 1.6.28, and enabled faster SSE2 decoding
- Updated WOFF2 code from upstream
- Updated the zlib compression library
- Made general improvements to internal code structure and spec adherence
- Fixed an issue with certain command-line parameters being used
- Updated the default theme to improve consistency and contrast of toolbar and download buttons
- Increased the default duration of notification pop-ups and made them configurable
- Improved handling of audio-visual media (ongoing)
- Fixed an issue in CSS where elements would sometimes reflow to the next line even with sufficient visual space
- Aligned the implementation of for(let x=y;;) loops with the final ES6 specification
- Fixed the selection system inside of a nested contenteditable element being broken
- Fixed Windows 10 detection for blocklisting graphics drivers
- Enabled pasting of clipboard data in documents without an editor element to improve web compatibility
- Fixed the uninstallation routine of restartless add-ons
- Fixed the handling of unimplemented functions in the console API
- Updated the Facebook user-agent to enable otherwise vendor-restricted functionality
- Updated the SVG scaling cache limit to be more lenient for larger SVG images at a small performance trade-off, working around some sites' design issues

Security/privacy fixes:
- Added an option to clear Site Connectivity Data (delete history)
- Removed stale entries from the HSTS preload list, and improved generation/processing of it
- Removed undesired certificate issuer organization to common name fallback (if issuer org is empty)
- Added pretty-printing for ECDSA-SHA224, 256, 384 and 512 hashed certificate signatures
- Worked around some more issues with broken Apple fonts
