As covered last month, 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 Firefox finally enabling Matroska support for commonly used codecs . The Matroska support covers the AVC, HEVC, VP8, VP9, AV1, AAC, Opus, and Vorbis codecs.
