After crashing of single tabs, total crash of tor browser (segmentation fault)
Summary
For about two months, several times I encountered the following situation: At first single tabs crashed, shortly after restoring tab, the same tab crashes again. Also the other tabs tend to start crashing. After several tabs crashings and restoring, finally the whole browser crashes. Restarting of the browser doesn't work. No GUI appears.
Steps to reproduce:
That only happens from time to time. Couldn't see anything which triggers this behaviour.
What is the current bug behavior?
Crashing tabs. Crashing browser. No restart of browser possible.
What is the expected behavior?
No crashing.
Environment
Arch linux - up to date. Tor browser download from torproject website.
Relevant logs and/or screenshots
Verbose output for trying to restart after browser crash. Browser doesn't start again. Final error: Segementation fault (core dumped)
P.S. How can I add line breaks in this markdown code environment, here? My usual method (three empty spaces at the end of the line doesn't seem to work)
$ ./start-tor-browser.desktop --verbose
Launching './Browser/start-tor-browser --detach --verbose'...
