Thanks for providing the stack trace, Lars. This shows the illegal instruction is happening in Skia, specifically SkJumper's implementation of _sk_xor__vfp4. To run with Skia disabled, edit your user profile at ~/.mozilla/firefox/*.default/prefs.js and add the following line:
user_pref("gfx.content.azure.backends", ""); Firefox 32-bit will then launch on Raspbian Stretch. Or if you have more than one user, you can instead edit /usr/lib/firefox/defaults/pref /vendor-gre.js I expect rendering performance is taking a hit with Skia disabled. For a proper fix we should figure out what's going on with the illegal instruction(s) in SkJumper_generated.S. This file is auto-generated so from what I can tell the armv7 version isn't readily available via git. I have yet to set up a build environment for Firefox, but if someone here has done so for Arch Linux and another for Ubuntu, we can diff and track this down. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1711337 Title: Firefox crashes at start on armv7L after 55.0.1 update Status in Mozilla Firefox: Confirmed Status in firefox package in Ubuntu: Fix Released Bug description: Firefox always crashes when launched after the 55.0.1 update on an Orange Pi PC Plus (a single-board computer similar to a Raspberry Pi), even in safe mode. I did a fresh install of Armbian (a Ubuntu Xenial 16.04 re-spin for ARM single-board computer) on a similar board (Orange Pi Plus 2e), installed Firefox and experienced the same problem--it won't load without crashing.
