Changes/Fixes:

Reworked the media back-end completely (thanks Travis!) to use FFmpeg (including support for FFmpeg v3 and MP3 playback) and our own MP4 parser, and no longer relying on gstreamer on Linux, as well as adding some improvements on Windows for media parsing and playing.
On Linux, Apple .mov files of the correct type will also be played through FFmpeg now, for those rare occasions where they are still in use, considering there is no Quicktime plug-in available on that operating system.
Restored the classic about:config styling.
Added a fallback to US-ASCII if the autoconfig UTF-8 conversion fails.
Improved cross-compartment wrapper handling when managing a large number of tabs (fixes a performance regression with v27).
Changed the way audio and video synchronization is calculated to account for (slow) device latency, preventing things from getting out of sync on e.g. BlueTooth-connected speakers.
Changed the way scripts are handled when they are stopped from the "unresponsive script" dialog, to prevent browser lockup. We will now stop all scripts in the affected compartment in one go.
Fixed several errors in the devtools.
Fixed a nasty crash caused by cross-origin referrers.
Fixed the installer to allow 64-bit versions of the browser to be installed on Vista again.
Added HTML5-spec clipboard handling for content (cut&copy only -- paste is not allowed for security reasons).
Made multiple changes to the toolkit jetpack modules to cater to PMkit extensions.
This should make running SDK-based modules as PMkit extensions fairly simple for extension developers. See the introductory text to these release notes.
Fixed a css layout issue: make max-width affect contributions to intrinsic min-width.
Implemented several updates to the permissions manager. Among others, Improved the permissions manager (aboutermissions) with a more complete set of permissions for pages.
Removed otherwise unused Metro browser platform/widget code.
Removed support for non-standard/deprecated let blocks and expressions.
Made the use of let as a keyword versionless and ES6 compliant.
Made the privacy category in preferences a tabbed setup to better fit the current options.
Fixed a regression preventing certain MP4 video files from playing.
Fixed a regression where seeking in media files would halt playback/jump to the end of the stream.
Fixed a crash caused by certain downloadable fonts with DirectWrite in use.
Improved downloads-button indicator legibility on some combinations of Windows versions and system theme colors.
Changed the Facebook user-agent override to be our native one, based on reports from users that it is (finally) working acceptably.
Fixed site-specific useragents being ignored if a global override is defined.

Security/privacy changes:

Changed CORS handling to allow data: sources, assuming they are same-origin. This should fix the infamous "Facebook endless reload" issue and may make some other sites that assume this particular (unspecified) CORS behavior happy with Pale Moon.
Reinstated the network.stricttransportsecurity.enabled preference so people who choose privacy over HSTS can do so again.
Added, In HSTS "off" state, prevention of HSTS site status from being written to disk.
Updated the IDN blacklist with more extended unicode characters that "look very similar to" normal ASCII characters, to prevent spoofing of well-known domains. If blacklisted characters are found, the IDN domain name will be displayed in its punycode form. (CVE-2017-5383 and similar)
Fixed an exploitable crash when using MP4 video. (CVE-2017-5396)
Fixed an exploitable crash in XSL parsing. (CVE-2017-5376)
Fixed a potential security issue when exporting certificates with specially-crafted credentials. (CVE-2017-5381)
Fixed a potential use-after-free situation in frame selection. (CVE-2017-5380) DiD
Fixed a leak of window details through the Ion compiler in certain situations.
Fixed the potential for an exploitable crash involving Javascript GC. DiD
Fixed a potential overflow situation in (non-released) WebRTC code. DiD
Fixed a potentially unsafe situation in websockets. DiD
Fixed several memory and other safety hazards (BMO bugs 1318766, 1325877, 1328834 DiD, 1288561 DiD, 1322420 DiD, 1293327 DiD, 1322315, 1325344, 1285960).

DiD This means that the fix is "Defense-in-Depth": It is a fix that does not apply to a (potentially) actively exploitable vulnerability in Pale Moon, but prevents future vulnerabilities caused by the same code when surrounding code changes, exposing the problem.

Tzn. to nie jest tak, że Firefox nie wspiera XP. Nadal wspiera i wesprze w kolejnej wersji 52. Będzie to ostatnia wersja i wsparcie będzie zakończone w marcu. Potem Mozilla pociągnie jeszcze wsparcie pewnie do końca roku, ale na innych zasadach. Poczytaj tu:

Inna kwestia, że nie pamiętam, kiedy Firefox był ostatnio lekki. W ostatniej wersji FF zwiększył wydajność wyświetlania video bez angażowania akceleracji GPU. Stąd może pochłania więcej pamięci, ale tylko gdybam.
Możesz jeszcze popróbować innych przeglądarek: Lunascape, SeaMonkey, Comodo IceDragon, Epic Privacy Browser, Avant Browser, QupZilla, Superbird, czy Light. Powinny jeszcze wspierać XP (nie bardzo mam czas sprawdzać). Daj znać co Ci podpasowało.

Implemented a fix in media handling to prevent crashes with concurrent videos and/or rapidly starting/stopping video playback in the browser.
Fixed the way the Adobe Flash plugin is detected to prevent confusion with other plugins that identify themselves as "Flash" (e.g. VLC).
Windows: Solved stability issues caused by the release build process, resulting in unexpected behavior (e.g. hangups).
