User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101 Firefox/78.0
Steps to reproduce:
Firefox started crashing on startup, so I fully uninstalled it (apt purge, rm -rf ~/.mozilla) and reinstalled it (apt install firefox). Runs the first time, after that it's hit and mostly miss.
During that first time usage I visited the app.element.io website, which asked to use my storage permission which I granted.
Firefox will start up successfully from the terminal when I simply run
firefox, but will not start up from the .desktop file in XFCE 4.
So, steps to reproduce:
- have an n year old linux mint 19.3 + xfce4 install.
- open firefox
- login to matrix/element online app
- close firefox
- reopen firefox from desktop
Firefox hangs, only showing the window frame. It also doesn't claim to be broken or anything, it will hang indefinitely.
When closing the window (alt+f4 or the close button) the DE will complain that the window/process is not responding, see screenshot.
Firefox opens and runs correctly when started from the DE.
