Firefox Support Forum

My Firefox can only be shut down by TaskManager, or by clicking on the three horizontal bars and then dropping to exit.

So I can't close any single tab 'without closing them all', that's the real annoyance. I also can't close any individual windows I opened instead of a new tab, without closing all tabs and windows. Finally the classic windows ALT+F4 closure that's built into Windows doesn't close Firefox, and if it did I suspect ALT+F4 would close them all. Bottom line Firefox is seriously close-resistant.

What precipitated this was I allowed a previous Firefox update to download-install, and it tanked my performance, I figured your team would fix that issue, but in the meantime what I did was uninstall that version and reinstall the version I had been running before that update. Tilt! That action resulted in the close windows or tabs problem.

Summary: I am using the latest version now, but with it came this "can't close any individual tab without closing them all, and can only close even then except by Taskmanager or by clicking the 3 horizontal bars then dropping to Exit which also closes all Firefox tabs and Windows. This problem has surfaced before in this support, and none of the solutions worked, probably because I got to this place uniquely. I did read before submitting this.

I have an issue where I go to website and I get a message that the website is temporarily available. I cannot go to a different webpage for what URL I want. I believe this has to do with history. I suspect I can get past this by flushing the history. I can get to the website I want by using a different browser such as chrome. Ho do I fix this?

I am having the same issues as the person in this thread, but unlike their situation, firefox has not fixed itself out of nowhere. https://support.mozilla.org/en-US/questions/1104044

Everything in the firefox browser looks like it was stretched it out in MSPaint, while my actual OS interface and every other app/software UI looks fine. I have tried simply restarting my computer, as well as every solution in the linked thread, as well as refreshing firefox, and uninstalling/reinstalling, which only served to mess up my shortcuts on the home page. To be clear:

• Hardware acceleration is turned OFF, as suggested in any thread I've found where a resolution issue is addressed.
• setting layout.css.devPixelsPerPx to 1.25 specifically makes it almost legible. Almost. It's still incredibly grainy. Any higher even a small portion of a webpage takes up a ridiculous portion of my screen, rendering it just as unusable.
• In messing around in config, I found that setting gfx.color_management.rendering_intent to 5 helped, in so far as it sharpened things up a little, but it did not FIX the issue. Any value above 5 seems to have zero effect or change.
• Absolutely EVERYTHING else except firefox looks absolutely fine. It is ONLY firefox that is having this issue of all the applications/interfaces on my computer.
• Everything in firefox is affected- images, text, the tabs and address bar, bookmarks bar, absolutely everything.
