Mozilla has announced the discontinuation of support for 32-bit Linux systems starting with the release of Firefox 145, scheduled for November 11, 2025. It is noted that maintaining Firefox on 32-bit platforms is becoming increasingly complex and unreliable, especially since support for 32-bit builds has already been discontinued in most Linux distributions.
Users of 32-bit Linux distributions are advised to switch to 64-bit operating systems. For those who cannot promptly upgrade their distributions, the ESR branch of Firefox 140 can be used, with security updates being provided at least until September of next year. Support for 32-bit Linux systems in Chrome was discontinued in 2016.
