White Star 29.4.0.1

This is an out-of-band update to address the following issue:

In 29.4.0, the optional FUEL component (long since deprecated precursor to the Mozilla Add-On SDK) was removed from Pale Moon. This had unexpected impact on a number of popular extensions as well as a few bits of core functionality that went unnoticed in our pre-release testing and unstable channel.

As part of our commitment to resolving issues and giving extension developers some more time to address any problems with this removal of the component from the browser, this update temporarily restores the FUEL component.

If you are an extension developer relying on FUEL components or namespaces (e.g. implicit 'Application'), please update your extension before the next major release.

Unified XUL Platform Mozilla Security Patch Summary: 3 fixed, 3 DiD, 2 deferred (DiD), 12 not applicable.

Implementation notes:

Brotli compression (introduced a few years back) has originally been restricted to https only in web browsers because there was some concern about interaction with middleware boxes with poor design trying to transparently recompress data not recognizing the new compression stream type and causing failures. The kind of processing done in those boxes (SDCH) has long since been deprecated. Since then, the segregation for Brotli between http and https has been maintained by Chrome and Firefox as a vessel to further promote https over http by artificially keeping http less efficient (denying the use of the more dense Brotli compression). Since there is no technical reason not to enable Brotli over http, we will accept (by way of Accept-encoding) Brotli over plain http from this version on, offering up to 20% less bandwidth use when servers also support it.
We maintain a blacklist of ports that should not be addressed from a browser (primarily to prevent scripted abuse). Not too long ago we updated these ports with a number of additional (higher range) ones, including port 10080 (Amanda). Unfortunately there is too much overlap with other common services/devices that also use this (arbitrarily chosen) port, so we've removed this particular port again from our blacklist.
The ResizeObserver implementation was changed to now support the updated specification for this API, including the experimental properties contentBoxSize and borderBoxSize which allows finer control to respond to size changes of elements. The old spec sizing property of contentRect remains supported for web compatibility.

White Star 29.2.1

Changes/fixes:

Worked around an issue with autocomplete popups sometimes failing to work (and added some debug console logging to it in case it happens to help find the root cause)
Fixed an issue with DOM mouse scrolling throwing errors.

Fixed a crash when using large uploads through DOM.

There were no security issues that applied to UXP or White Star this release cycle.

Security issues addressed: CVE-2021-29946 DiD and CVE-2021-23994 DiD .
Unified XUL Platform Mozilla Security Patch Summary: 2 DiD, 14 not applicable.

Implementation notes:

This version adds support for the prefers-color-scheme CSS keyword. This keyword is a media query keyword that indicates to websites whether your content styling preference is "light" or "dark". Unlike other browsers where this will be tied to your system color scheme and determined automatically (which might be a point on which you can be fingerprinted, so this would be a privacy concern), we've decided to give the user control through Preferences -> Content -> Colors where you will find a new control to indicate your user preference (it defaults to "light" for everyone). While this control also gives you the option to disable this feature and effectively not support the keyword, be aware that this might cause issues on some websites that do not provide styling for "unspecified" color scheme preferences.
In the future we may add an "automatic" option similar to other browsers in case you regularly switch your system application style from light to dark and v.v.
