Firefox 144.0 is now available but it's not a particularly exciting browser release. But with Firefox 144 stable now comes Firefox 145 beta and that is a bit more noteworthy as it ditches 32-bit Linux support.

As covered last month, [1]Firefox is ending 32-bit Linux support with the Firefox 144 series being the last to support Linux 32-bit or Firefox 140 for the ESR series.

With Firefox 145 Beta now available, 32-bit Linux is no longer supported with their new releases moving forward. Mozilla is encouraging users to install a 64-bit version of Firefox.

Aside from ending 32-bit Linux support, Firefox 145 Beta isn't too exciting but does make horizontal tabs now slightly more round, a few JavaScript additions, and then [2]Firefox finally enabling Matroska support for commonly used codecs . The Matroska support covers the AVC, HEVC, VP8, VP9, AV1, AAC, Opus, and Vorbis codecs.
