Darn, and I see the same error with Firefox 59. Your stack trace still shows the illegal instruction in sk_xor__vfp4(). It seems like something is now running Skia even when it's disabled in the config.
Among rendering differences, from the Firefox 58 blog post there's those changes for OMTP which could have affected this: https://mozillagfx.wordpress.com/2017/12/05/off-main-thread-painting/ If it's now going into Skia when it shouldn't that's a Firefox 58 regression. It would be somewhat of a bug affecting non-armhf platforms too so we could finally get the attention of the Mozilla team. Meanwhile the bad assembly in SkJumper_generated.S still seems like an Ubuntu-specific problem. Is anyone able to reach the Ubuntu dev team on IRC so that can set this bug's status back to "confirmed"? -- 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.
