This is an intentional upstream change which also affects the binaries provided by Mozilla: https://support.mozilla.org/en-US/kb/your-hardware-no-longer-supported It might be possible to disable the use of SSE2 for the i386 architecture (as every CPU covered by amd64 supports SSE2), but I have no idea how intrusive that would be (and might cause some problems in the long term if the non-SSE2 code paths are not covered by upstream CI/tests). It's also one additional patch to be carried forward until i386 is retired as an architecture. Cheers, Moritz
