Black Screen - Firefox

I semi-regularly end up with a black screen after using Firefox after some time;

I’ve lived with it for a while - I can just restart/restore the browser, but I’m wondering what I could do to either resolve my issue, or provide information should it continue to happen (it will).

The usual FF troubleshooting. Start with add-ons disabled, create a new profile and use that one for awhile to see if your current profile might be corrupt.

about:support gives some options e.g. Start with Addons disabled.

Thank you kindly! I will start with disabling some addons then slowly see how it goes.

i get this issue on all browsers

i literally just installed vivaldi and it happens on this browser too
