Yes but generally, it’s to find solution, not just to have someone listen and do nothing else. It’s just a bonus I would say if the person listens as well.

Do men do that? I have the feeling it’s exclusively women who do this, but the reasoning behind it could be as valid for women as for men. We’re all human after all.

Pop!OS is a pretty stable distro, so there shouldn’t be any dependencies problem: you usually have that on arch or arch based distros, even if it’s quite rare. Have you ever uninstalled Firefox and reinstalled it but without some of its dependencies? Or ignored a package it asked you to install with it afterwards? If not, maybe it’s just an update that went wrong, like the PC shut down during an update or something. So update your system, uninstall firefox and reinstall. Your data stored in your home directory (in .mozilla, a hidden folder) like your history, extensions, opened tabs, should be conserved, even if you use apt purge.

Unless it’s a RAM filling issue, because you would have too little RAM, and even then, the entire OS crashing and not just Firefox would be very unlikely, I don’t see any reason for it to crash your entire OS. Regardless, there are Firefox forks that use much much less RAM. You’re using Windows, Mac or Linux first? Try to uninstall, clean everything and reinstall with a new profile, it may work, who knows. If not, then it has to be your OS.
