qubes tor-browser crashed (hangs) want to save bookmarks

Hi, in a qubes whonix disposable vm a tor-browser was running with about 30 tabs in it, not yet bookmarked, and it crashed and isn’t responsive anymore in any way.
Does anybody know if there is a file with currently open tabs and where to find it?
If not, any other way I can bookmark and save my open tabs?

Thanks.

Same as Tor Browser. Similar to Firefox.

As per Free Support for Whonix ™

Not really because in the regular Firefox there is a sessionstore.json where the tabs are stored. The makers of the tor-browser used in whonix seem to have removed that file as I can not find it inside those VMs that are still running with the non-responsive tor-browser.

Whonix doesn’t produce Tor Browser. The The Project produces Tor Browser.

Whonix doesn’t make such modifications such as deleting files from Tor Browser.

Tor Browser in Whonix is in folder

/home/user/.tb/tor-browser

That’s the only relevant difference introduced by Whonix here.

Not a Whonix specific question.

I’ll try to find a support group for tor-browser.
Thank you.
