Hi, I run firefox on Linux Mint 18.3 Cinnamon with kernel 4.15.0-36-generic inside Virtualbox (InnoTek Systemberatung GmbH VirtualBox Graphics Adapter (prog-if 00 [VGA controller]). Since I believe Firefox 68, I got systematic tab crashes on various website like old.reddit.com bloomberg.com/europe or the login page of amazon.fr What I tried with no result : removing all extensions, cleaning and then creating a new profile, uninstall purge and reinstall firefox, disabling hardware acceleration, rebooting several times the VM. It only works with Firefox in Safe mode so there's hope. When the tab crashes, there's no option to report the crash so about:crashes is empty. My VM has plenty of RAM (1,8 GiB used of 7,8 GiB) so I don't think it's due to an OOM killer. Thanks for the help, I would like to keep using Firefox.
