Nearly a year later, this is still an immediate problem. For people finding this bug via Google, the only fix I've found that cares about security is to use Debian GNU/Linux instead of Ubuntu and `apt install firefox-esr`. This works because the stable (Stretch) version of Debian uses Firefox-ESR 52.9.0 which was released last month (https://www.mozilla.org/en-US/firefox/52.9.0/releasenotes/).
However, I notice that the next Extended Support Release of Firefox will be based on version 60, and thus I presume will have the same SIGILL problems due to an incorrect ABI if it is compiled in the same way as the current Firefox. So Debian will not be a panacea. I understand that time marches on, as do ABIs, but minor updates to an Ubuntu LTS release should not add new requirements on the CPU architecture. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1697800 Title: [regression] firefox dies with SIGILL on machines without SSE2 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1697800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
