Bonjour,
Récemment j’ai mis à jour Linux Debian 8 release 8 ainsi que Mozilla Firefox 53.0.2 sur une machine 32 bits processeur AMD SEMPRON 2200.

/usr/local/firefox
./firefox
This browser version requires a processor with the SSE2 instruction set extension.
You may be able to obtain a version that does not require SSE2 from your Linux Distribution.
Apparament la communauté Mozilla ne mantiendra plus les anciennes architectures :
Firefox Extended Support Release (ESR) will continue to work with older processors but will not receive updates beyond ESR version 52. Firefox ESR version 59, scheduled for release in March 2018, will no longer be supported.
