After a mistaken forced restart (inadvertent pressure on the shutdown/start key), one of the 3 windows I had open is invisible. It shows in the 'Windows" menu as one of 3 but when I select it - nothing. It does not show as a recently closed window in History. I have restarted Firefox multiple times, including deleting the xulstore.json file then restarting (a fix from another similar thread).

How can I restore this inaccessible window?

Thanks

2013 Macbook pro running Big Sur 11.7.4. The escape key no longer works when using full screen mode to return to the Firefox browser. I must quite and restart Firefox anytime I am in full screen mode. My escape key works on full screen mode on other browsers.

Hello! I ran into one problem - my pages self-reloading. Even if i am on page, i can watch video on YouTube or read more articles - in one time page just self-reloading.

My PC have a 32GB RAM, so i don't think what problems is in my PC or insufficient memory. What the problem could be?

frequently I get this message on Firefox: "The page isn’t redirecting properly

Firefox has detected that the server is redirecting the request for this address in a way that will never complete.

   This problem can sometimes be caused by disabling or refusing to accept cookies."

how can I fix this?

I came back to Firefox - which was my preferred browser for many years - because Chrome is a big fat memory hog, and would spend quite a while swapping pages into memory if it had been out of focus for a while. Opinions at the time varied widely, but suggested Firefox was more efficient.

Nope.. Firefox is at least as bad. And worse; it can't maintain a connection to Gmail which forces me to completely restart the browser every day. Mention this to Mozilla support and all you get from the devs is, "I don't experience this (on my high-end dev system) so it can't exist". Yeah, I'm running Firefox in the 2GB left over on my 8GB laptop - how hard can it be to write efficient code.. memory hog or slightly worse memory hog isn't much of a difference to me.

And of course I cant get the extensibility I used to have; and the constant pestering every-single-time the browser gets focus to do an upgrade. Going back to Chrome; though I expect things to get shaken up for the better soon enough (so over this old-skool grind with poorly functional, slow and unreliable software: bring on the AI)

I recently needed ti reload a Windows 7 backup and then re-upgrade to Windows 10. Now, whenever I open a new FireFox window I get a banner warning from K9 that says "You must log in to this network before you can access the internet." It shows a button "Open network login page." which attempts to go to the K9 page which is long since out of business. I uninstalled the software and re-booted, but still the message appears every time a new FireFox window opens. Before I go the dangerous "regedit" route, is there any way to easily remove this annoying thing?

I've had this problem for a couple of years already. Not with other browsers and, with the Internet Download Manager extension, I'm usually able to download multimedia content in FF. (That's been my workaround.)

For example, when loading this humble URL ... https://upload.wikimedia.org/wikipedia/commons/transcoded/d/d8/Plattenknistern_record.ogg/Plattenknistern_record.ogg.mp3 ... if I have autoplay enabled, it'll crash right away ("Your tab just crashed"), without autoplay, it'll crash as soon as I hit play. Until a few days ago, no crash report was created under about:crashes, but, after upgrading to 112.0.1, I've finally been able to submit a crash report: bp-203a462b-e949-47b0-90f3-a99760230422

No difference if I create a new user profile and disable add-ons. Disabling hardware acceleration doesn't help either. I can't do without most of my settings and add-ons, so refreshing FF is not an option. I'd sooner try a new install (and then import my profile and reinstall add-ons), but that's laborious and not guaranteed to solve the problem.

(I've submitted this question before, about half a year ago - now archived -, but that didn't go anywhere for lack of crash diagnostics.)

I've been having trouble staying signed in on websites from Google (youtube, classroom & etc.) while using Firefox. I've tried everything from clearing cookies and allowing all cookies to reinstalling Firefox and removing all extensions, but the issue persists. I've also read other similar articles but they didn't work either. What steps can I take to fix this problem?

After upgrading to the latest version (112.0.1) on MacOS 10.15.7, the bookmarks toolbar disappears when I enter fullscreen mode ('Always Show' is selected under Bookmarks Toolbar in the View menu). When I exit fullscreen mode, the toolbar reappears but a large grey bar then appears at the top of the window (see screenshot). I've read answers in the knowledge base that suggest that the toolbar always disappears in fullscreen mode, but I am 100% sure that this behaviour did not exist before the recent upgrade (perhaps this behaviour has been around for a while in Windows?). Either way the grey bar is clearly a bug and feels related to the toolbar behaviour. Has anyone else experienced this?

Hello, I have an issue with audio in Firefox As an example this website: https://www.radiofrance.fr/fip/radio-nouveautes It's a radio, when I hit play nothing sounds, but after reloading the page it works and play sound. Do you know how to fix that? Best regards,

All of a sudden a game on Facebook stopped loading. This is the URL "https://apps.facebook.com/playfantasyslots/?ref=bookmarks&count=0" Had no problem prior to this week. If I use Chrome, game loads normally. What's causing Firefox to not load the game?

This just started happening today, but some pages just won't load at all. It will show that it is loaded in the tab, but the page is just blank. Or, the page will load but it won't load images or fonts and is fairly basic. This hasn't happened on every webpage, but most of them. I tried clearing my cache, which didn't help (it actually seemed to make it worse), and I'm not really sure what else to do. I've attached a picture of what "scotusblog.com" is giving me.

I recently updated to Version 112.02 and all of a sudden PDF documents will not open. Please see attached screenshots. Does anyone have any ideas to fix? The only solution that worked was re-installing an older version of Firefox but I don't want to run an old version.

Tried to open MS Outlook live and twitter this am Outlook just hangs and twitter says no network Every other site works OK just those two Tried on chrome all connecting perfectly

Firefox was working like a charm on my MacBook Pro '16 19 with Venture 13.0 macOS, without any issues. But somehow, after I did upgrade to Venture 13.2.1, Firefox started random hangs/freezes after each 30-60sec. And it takes ~5-10sec. I started to get random panics 2-3 per day.

I did not changed anything in the settings. This also happens in Private Window mode. I usually restart the computer everyday. (Eventually a new Firefox instance each new day, before Ventura 13.0 and still do after upgrade)

I have read the followings:

• https://support.mozilla.org/en-US/kb/diagnose-firefox-issues-using-troubleshoot-mode
• https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

But didn't help me. I have everything (tabs, favs, extensions, works, etc.) so that I do NOT want to reset/refresh ANYthing. I'd prefer to fix the root cause and understand the issue why it keeps occur.

I either change my main Firefox browser (after 8+ years) or look for a solution to fix the root cause without doing any refresh or reset (or something that cause data lost).

Is this a known issue?

Could you please help me on this? Thanks!

My Environment:

• Firefox 110.0
• macOS 13.2.1

Also, in the Troubleshooting Information section below, browser somehow couldn't collect to data and showed a "manual way documentation" button. I clicked it and it redirected me a doc. When I back to previous page, I lost the data I've just written here. So had to rewrite everything... Can you please fix this?
