I have this ennoying issue since some months and didn’t find a way of fixing it, even by completely deleting the app and removing all remnants of profiles before re-installing it. If I leave Firefox open when I shut down my computer, most of the time (but not every time!) at startup instead of opening the last window with its tabs, Firefox displays the KDE Plasma’s or OpenSuse’s splash screen (the lamp bulb on a black background) and no menu.
If I minimize the window, and maximize it again, it displays a screenshot of my desktop!.. I can’t do anything but close the window and re-launch firefox, but then the history of last closed windows is gone.
I have the same version of FF and the same version of OpenSuse on two other computers and never had this issue on them.
I would be grateful to anybody who could give me some tips to solve it or investigate. Thanks for reading.
I do not think it displays either. It sounds like compositor does not repaint screen area where Firefox should be showing its content and Firefox displays nothing (which also explains “no menu”) or its content for some reasons is not shown by compositor.
It looks like video acceleration issue. You could start with comparing with systems which work - do they have identical configuration, are drivers the same etc.
Hi arvidjar, thanks for your suggestion. I’ll give it a try, but except that all machines run Leap 15.4, everything else (motherboards, graphic cards…) is different. And since they’re at my work place, I must wait till monday now. But the graphic drivers will be necessarily different, won’t they ? So I don’t know what to look for.
One thing I can say, I added a graphic card recently and it didn’t change the problem which occured before with the integrated cpu graphics.

Apart from the video acceleration issue, there could be something in the cache which is provoking the behaviour –
Either in the Mozilla Cache located in ~/.mozilla/firefox/???.default-release/ → clear this cache with the Firefox settings;
or, almost anything in ~/.cache/ except for ~/.cache/mozilla/firefox/???.default-release/ → which should also be cleared by means of the Firefox settings …

Glad to learn that french towns can be partners !
Apart from the video acceleration issue, there could be something in the cache which is provoking the behaviour –
Either in the Mozilla Cache located in ~/.mozilla/firefox/???.default-release/ → clear this cache with the Firefox settings;
I’ll clean this caches before shutting down, and see what happens next at boot up. It could take some time, since as I told before the issue appears randomly and not all the time …
or, almost anything in ~/.cache/ except for ~/.cache/mozilla/firefox/???.default-release/
There are a lot of folders and files there ! Should I safely remove everything ?
For the moment, I just cleaned up firefox cache from firefox settings and had 2 startups without the problem appearing… but the sample size is a bit small…
Not really random of course, it just means that I didn’t know what caused a failure which appeared to me as unpredictable … so I don’t know yet wether it’s fixed or not.
I’m almost sure that I already cleared the cache again before the last update when the problem was there again.
But there is no harm trying again. This time I deleted the cache contents but also data and cookies. No problem today, Firefox opened up correctly. Wait and see.
Maybe it will fix that weird issue. I’ve never read about a similar one on the net. And it’s still there, still apearing randomly at bootup and thought I cleared the cache and deleted cookies and sites data.
