Comment 10 for bug 1697800

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.
