When I open Firefox it's just a black page and anything I click on isn't responsive. I can't go into options or anything. Sometimes Firefox doesn't even load. It worked fine earlier than all of a sudden It stopped working today. Web pages don't load. Nothing works

I seen a post earlier that had a link to a supposed fix but I couldn't figure it out. So if anybody is able to help me it would be much appreciated. I am not an advanced user when it comes to Firefox

The blocks where code should be displayed like on screen and on stackoverflow displayed in a weird manner : replaced with [Object object] i don't have any extensions that might cause that

When doing some online homework in Firefox, my computer froze. I couldn't move my mouse or open task manager or do anything. I had ~12 tabs open to my online homework and Discord and TextMaker (a free Word alternative) running as well. I hard shut off my PC by holding down the power button. Upon startup, FF won't open. I click the shortcut and my computer has the little loading circle next to the mouse for a second, but then it disappears and nothing happens. If I try to open a PDF in FF or click a link to open in FF, the same thing happens; a loading circle next to my mouse cursor and nothing. I refreshed FF to no avail. I reinstalled FF, and nothing. I restarted my PC, and still no dice. FF doesn't appear in my task manager when I click it.

I tried running the firefox.exe -P command in the run menu and the start menu to manage my profiles and the same thing happens, I get a loading circle by my mouse and nothing happens.

I really like FF and use it for my schoolwork. Can anyone help me troubleshoot?

So today, February 17th 2023, the first time I turned on my computer, opened firefox, then went to a website (Twitch) the site was loading very slow and while thinking "oh is Twitch having issues again?" my computer completely crashed, which has never been caused by firefox or any browser before. I started my computer back up and firefox itself wasn't working properly, opened a separate browser to troubleshoot my issues, so I did run in troubleshoot mode, I do have a "old firefox data" folder on my desktop, I tried copying the suggested files on there to the new profile folder. My bookmarks bar won't show my bookmarks even though I can see all my bookmarks under the manage bookmarks view. The 3 bar menu on the top right of the browser won't do anything when I click it so I have to do the "alt" key option of menu for everything. I did a security scan of my computer because I got paranoid and everything is showing as fine, so I don't know what could be causing this other than maybe the recent update. I didn't have a lot of extensions just UBlock Origin, Tabliss, and Honey. Should I just uninstall and reinstall firefox?

I recently installed new pc with fresh Firefox Developer Edition. Then I transfered the profile folder from old pc to the new pc. All bookmarks, addons, etc is there. Just the XULRunner popup appears only on the new pc. I uninstalled firefox on the new pc again and reinstalled it with profile cleaning. After profile cleaning firefox got faster and addons got removed. But the XULRunner popup keeps appearing. When I go to taskscheduler and trigger the "Firefox Developer Edition Background Update CA9422711AE1A81C" again, the XULRunner popup appears. Removing this taskscheduler and Firefox keeps readding it and the XULRunner popup are back. Any idea how I can get rid of the XULRunner popup?

Mouse scroll wheel not scrolling web page after installing Firefox version 110. I installed an older version, 98, and it worked again, but that version would not use my profile and it seemed to update itself to 110 and then scrolling was broken again. Am I alone or is everyone broken at version 110?

Hi there. My scroll wheel on my mouse stopped working. Only way to scroll is to press Ctrl+Shift and then use scroll wheel, which makes it work fine. But i would prefer to not have to press down Ctrl+Shift to scroll. This problem is only happening on Firefox and no other browser or program on my computer. Do you know any solutions?

Firefox always uses excessive GPU memory when I watch video and livestream. about:memory shows that the explict GPU memory allocation is only about 200 MB but in the task manager the GPU memory usage is 1GB, and the latter doesn't decrease even if I close the tab. I suspect that this is a memory leak. I searched for Bugzilla and found a similar issue that has been existing for years: https://bugzilla.mozilla.org/show_bug.cgi?id=1386177

I've been using Firefox browser for over a decade to do university business (e.g., submit grades, internal proposal review processing and approval, etc.). But since December, I am having catastrophic failures. Sometimes with an error message, sometimes just getting no response at all when submitting information in a browser-based university application. And yet, I can complete those functions when I immediately go to Chrome (once I remember that that might be a problem). I really don't want to use Chrome. Is there a change in Firefox (including something which I can change some settings in my browser to counteract), or a change in our university's software making Firefox incompatible? One returned error today was "Request Header Fields Too Large. The server refused this request because the request header fields are too large." [PS, I had to type this all over when I tried to share data with you about my system -- I had to click on "troubleshoot" information, which lost all the data I had previously entered... Sigh....]

OS version: Ubuntu 22.04.1 LTS (jammy), 64-bit (amd64, x86_64). Firefox version: 110.0 (64-bit) (NOTE: the issue was noticed with version 109.0, too)

Firefox package was installed on Ubuntu through 'APT', using the Mozilla Team repository (https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/). It caught my attention that an excessive amount of Firefox related 'DENIED' AppArmor log messages is generated during the browser activity.

According to messages, Firefox is occasionally denied read access to '/sys/devices/' area and read/write access to 'oom_score_adj' target in '/proc/'. Could somebody clarify why would that access be required for regular browser operations? I'm a bit puzzled as I haven't noticed anything similar with the older Ubuntu and Firefox versions. A complete suppression of those messages is also an option as long as there's no negative impact on application's performance.

I already posted this question to Ubuntu forum but seems like nobody there could provide an explanation. I'd appreciate any input or hint.

Following is the sample of referred log messages:

I am using Firefox 102.8.0esr on openSUSE Leap 15.4. Two days ago Firefox stopped playing video clips on websites, notably BBC News and Facebook. On BBC News I get the error message "The content is not available in a compatible codec" but elsewhere just "video cannot be played". I have checked that the same video clips can be played without a problem in Google Chrome

Hi, I'm using Windows 10 and no malware or anything detected by my primary AV, bitdefender. I also tried with AVG but same results. Website works normally for about 5 seconds and then automatically redirect to http://www1.cdnsure.com/?tm=1&subid4=XXXXXXXXXXX=CDN%20Network&KW2=CDN%20Performance%20Monitoring&KW3=CDN%20Video%20Streaming&searchbox=0&domainname=0&backfill=0

(XXXXX are random numbers. I just replaced just to make sure nothing personal is there.)

Chrome, Edge and others works normally. Tried skip redirect extension, but no use. Tried VPN, tunneling, but same results. I don't care much about security. So if there is a way to stop redirecting part, please help.

FF is my main browser and I don't want to reset or reinstall.

It only happens in Firefox. I can't open any website on Firefox , even google.com . However, the following link is what opens instead : "http://www1.cdnsure.com/?tm=1&subid4=1677529420.0141530000&KW1=Google%20Cloud%20CDN&KW2=CDN%20Solutions&KW3=CDN%20Video%20Provider&searchbox=0&domainname=0&backfill=0"

idk what's that "www1.cdnsure.com" website .

Firefox keeps attempting to access a web site with an unwanted application. The site is mv.outbrain.com and my virus software keeps asking to block the site. The popup is now becoming a nuisance how do I stop it or delete the reference to it

Two updates ago, I had an issue where if I used any Google web products, I had weird network problems that just didn't go away (4000ms ping spikes every 5 packets). I noticed it was only when I was using Firefox, so i tried disabling add-ons and extensions, it still happened. I opened it in safe mode, it still happened. I tried using Chrome and Edge, both did not cause issues.

I reset my Firefox completely (There was some custom CSS to put tabs on bottom, where they belong) and it was perfectly fine! No issues! Everything was great for a few days!

Then you guys updated things again... and it was back... so I reset my Firefox again, and even straight out of the box, its still causing the issue, but now only when using google products, with or without add-ons, there is no custom CSS anymore either.

I do not know why its an issue, but it is, and it is ONLY with Firefox, and I really do not want to switch to Chrome or Edge... It also persists after Google is closed, until I restart Firefox.

I am unsure of specifically why this is happening now, but it is a MAJOR problem for me

Maybe this is obvious and I just don't know the proper terms to find a solution, but I've recently lost the little loading icon that spins in the left hand corner of a tab when you load a site (see gif). No idea what happened to it, but I've tried refreshing and reinstalling to no avail. Yesterday I reinstalled Windows 10 on my machine (not because of this) and it worked correctly until I booted up this morning and it's switched back to that weird icon. Any ideas how I might fix it? Could something like a windows update have messed it up? I miss that little spinney icon more than I would have expected.
