My Firefox browser seems to have reset itself to Windows 8 compatibility. I have Windows 10, 64-bit. Firefox will not open full screen, but opens a tiny, narrow window at the bottom of the screen which I have to use task manager to close. I remember one of the automatic updates coming through a few days ago.

Can I do anything other than uninstalling and a new install? I'd like to keep my favorites list, etc. I am at the extent of my computer skills with this.

I have many tabs like 200-300. Firefox crashed today. I also have 4GB page file on top of that. Strange! After I restarted Firefox it was using only 6.8GB RAM. Perhaps memory leak. BTW if I have browser.cache.disk.enable set to false. Is page file still used?

Thanks for help.

Frequent crashes. I've run Onyx. Reset extensions. Reinstalled firefox. I've been using google maps frequently, so I switched to safari and that crashed too. Trying chrome now -- no problem yet. I'm wondering if GPU is at fault. I've ramped up cooling based on GPU. Still crashing. Tried holding down D and option D to test ram but I just get a command line on a non-responsive screen.

Hello there to anyone who can help me with this problem that I'm having right now. Yesterday while watching and going through the videos on youtube, while watching a video, it suddenly started to lag and not move as smoothly much as before when I have on a higher quality like in 1080p 60fps or 720p60fps.

This has happen to me a couple times before when I couldn't find a way to fix it like when my my laptop was acting stupid and was resetting itself and showing a blue screen when it happen and had someone help me take it to the store and have it fixed and the reset my laptop or something and had to go redownload Firefox and I think the problem stopped working.


Yesterday and today I tried searching and looking up how to fix this and find answers that tell me to go to the about:config and change somethings to false or true whatever and it still has this problem. I hope changing it to whatever doesn't mess it up anything even more.

I thought I had to go update Windows or something since recently a couple of times the youtube videos get stuttery and not move as smoothly at times. I can't remember much this one but I either just close Firefox to hopefully that it goes back to normal or I have to update Windows to restart my laptop and it works and it goes back to normal.

But this time when I did all that and I try to update Windows from my laptop it was doing what it does updating installing or downloading yesterday. The problem is still there and the videos on youtube are still stuttering. And I try to see if there were more things to update there was nothing there and says its up to date.

I linked a video that has a 60fps option on a another browser Microsoft Edge to see if it works from there and video when putting it on 60fps works fine there. So this must be a Firefox problem or something.

So if anyone can help me with this problem. Please tell if there's anything else I can do to get these videos on youtube to work on Firefox in 60fps and hopefully can try to easily fix this and hope its nothing complicated to do. Or if there is a bug or something that's making these videos stuttering and everything please try to fix this problem that's going with me right now. Cause i don't want to have to deal with problem I had before again forever and/or if its permanent.

Hopefully maybe the next update for Firefox might fix this problem I have from these youtube videos, but I don't know. Whenever an update for Firefox happens sometimes, the videos on youtube start to stutter and not move as smoothly with putting it on 60fps and have this problem again.

Thank you if anyone has the time to look at this and hopefully someone can get me the answer to finally fix these videos that are freezing stuttering and stuff there.

Recently I’ve been receiving a 522 timeout error in Firefox attempting to reach URL www.cocoontech.com. The 522 is returned from Cloudflare’s reverse proxy servers (see uploaded image). However, I can successfully reach that URL using Chrome and MS Edge browsers. Only Firefox receives the 522 error. I can access numerous other websites with Firefox, so it seems to be isolated to just www.cocoontech.com. I’ve looked at numerous settings in Firefox, but have not seen anything that seems relevant to this issue.

Any ideas where to look to resolve this issue?

Firefox crashes and restarts my computer all the time.

What happens: Suddenly the screen just goes black and my PC boots up again. Like the power was cut for a second.

When does it happen: It started in the last quarter of last year. It happens randomly when firefox is open and multiple times a day! It does not matter whether there is heavy load on the system or just few pages are open and I'm not even doing anything. I think it has happened only once while gaming (but the firefox was open that time). And generally with heavy workloads (gaming/solidworks) the PC runs just fine. Since it started I have done two clean installs of Win 10, "refreshed" the firefox, tried disabling all extensions, disabled hardware acceleration. The crash still happens.

The crash: The windows event has two errors after reboot: Event ID 6008 and 41. The crash happens so suddenly, there are no crash logs when windows boots up. It seemed so odd that I started to suspect my PSU is broken. BUT THEN I used edge browser and my computer didn't crash for a WEEK.

I miss using firefox to sync my stuff between mac, android and windows without having to log into big corporation account. But since starting to use firefox again, the crashes are back just as before.

Any Ideas how to fix this?

Each morning, when I first cold boot my computer, the moment I open my Firefox browser, I receive numerous (10+) identical error messages from Bitdefender:

Suspicious connection blocked: Feature: Online Threat Prevention

firefox.exe attempted to establish a connection relying on an unmatching security certificate to content-signature-2.cdn.mozilla.net. We blocked the connection to keep your data safe since the used certificate was issued for a different web address than the targeted one.

Question: Is this ACTUALLY coming from Firefox? If so, please match your security certificates! If that's impossible due to a technical issue, then please email me your confirmation so that I can add an exception to Bitdefender.

Question: If it's not coming from Firefox, please email me, letting me know what additional system information you require so that we can get to the bottom of who/what is masquerading as Firefox while attempting to establish an unauthorized Internet connection from my computer.

HP Envy laptop, Windows 10 OS, latest update.

This has been occurring for several months.

Thank you for your time.

Since yesterday, I did the update to FF84, FF permanently crashs - not even the crash manager opens thereafter. I run FF upon a Windows 10 Home 1909 system. I have tried re installation - no effect I have run FF from a differen Account - same problem I have startet FF in secure mode - same problem

I have found the dump files at AppData\Local\CrashDumps but as FF does not run, I have no idea how to analyze it.

I am in despair and soon so far that I switch to Crome...

Has anyone any idea? Thanks, magu

A mess! Every day the customized toolbar disappears. And I need to customize again .... This has been going on for some versions (current 84.0.1) And even if you copy the xulstore.json folder and the entire extensions folder to the profile folder, it doesn't work. Every time I quit Firefox and open it again, I lost all the customization of the toolbar ... I've seen all the posts on support, and nothing solves me ... What can I do? One of the reasons for not abandoning Firefox is its ability to customize with extensions, etc. But everything is lost .... every day !! w10 x 64, Home

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.

The last Firefox updates have suddenly created havoc. None, absolutely none of the websites that I frequently visit will have my login information saved even though when I view logins in the settings mode, they are all listed there with the correct passwords. I am not technical and would sincerely appreciate a tutorial of some kind as to how to correct this egregious oversite on behalf of the Mozilla team.
