The Pale Moon team released version 28.2.0 of the web browser on November 13, 2018 to the public. The new version is a major release that includes fixes and improvements.
Pale Moon 28.0 was released in August 2018. It was a special release because it moved the web browser to the Unified XUL Platform which can best be described as an update version of classic Firefox code.
Several projects migrated to the platform since its initial release. The developers released Pale Moon 28.1.0 a month later to address bugs and fix security issues.
Pale Moon is a browser that stays true to the roots of classic Firefox; it supports the classic XUL-based extensions system which Mozilla dropped with the release of Firefox 57. The browser is not a 1:1 copy of Firefox, however, as the developers have modified it heavily in some regards.
Pale Moon 28.2.0 is available for download at the project website. Admins and users who run it already can run a manual check for updates under Menu > Help > About Pale Moon. The browser queries the update server and should pick up the new version in the process.
The new version improves browser security by implementing security fixes for several vulnerabilities and bugs. Mozilla patched security issues in Firefox 63.0 which it released in October 2018.
The release notes list several compatibility improvements that found their way into the new Pale Moon version. The developers increased the reported version of Firefox in Firefox Compatibility Mode to reduce website prompts that state that the browser is too old to use certain functionality on sites.
Other improvements in this regard are experimental support for AV1 videos and improved media handling. AV1 media support is limited to AV1 in WebM videos currently, and it is disabled by default.
Pale Moon users need to set the value of the preference media.av1.enabled to true on about:config to enable support. Support is limited as MP4 and MSE Av1 streams are not supported yet.
The developers fixed major issues in the new version of the browser including a major performance regression with web workers or a crash on local networks.
Support for Asynchronous Panning and Zooming was added to the desktop version of Pale Moon, and the default scrolling behavior for menus and pop-ups was switched to allow scrolling in these contexts.
Pale Moon users may want to upgrade as soon as possible to apply the security updates to the web browser.
