Firefox supportforum

Hey folks, hopefully you can help with this mysterious issue!

I've been running Firefox successfully on my Windows 10 PC for a long while now. Last night, for some reason it simply ceased to work. New windows and tabs would not load any content. I also couldn't access the Settings at all (clicking on Settings in the browser menu produces no results or feedback.)

Yesterday, I had Firefox open all day (I usually have my computer on all day), and it was working fine. Around 8 or 9pm, I first noticed that none of my open tabs were loading any content, and the tabs had the "loading" animation playing. New tabs would also not load any content. I assumed it was an internet issue as I did see my internet connection get disrupted once or twice. I did not see anything (apps, etc) on my PC updating.

This morning I found Firefox was still not loading anything, although my internet connection was fine. I tried opening Chrome, and it ran just fine. Everything else that it is internet or cloud based on my PC is running fine too. So it seems to be an issue just with Firefox.

I have listed my steps to troubleshoot below, but I want to note one weird thing I observed: Even when Firefox is closed, and Task Manager doesn't show any Firefox processes open, my PC seems to think Firefox is running. For ex. while trying to uninstall Firefox or delete certain files, I would get a warning to "close Firefox first" or "can't perform this action while app is running." After seeing these, I would again confirm that Firefox appears closed and Task Manager shows no related tasks.

My PC build: - Windows 10 Home, 64 bit - Version 20H2 at start of issue (updated to 21H2 during troubleshooting) - OS build: 19044.1526

Things I have tried for troubleshooting already: - I have WebRoot on my computer due to my job, and I asked our IT staff if they could see WebRoot blocking anything related to Firefox on their end. They said it was not. - Used "Firefox Refresh" - Uninstalled and reinstalled Firefox - Cleared app cache / app data - Updated Windows from 20H2 to 21H2

How do I keep Firefox from losing the internet connection just cause I don't want to close all the tabs I've had open the past week or so? I've tried clearing the cookies, and then reloading my open tabs, but it ends up losing the connection, just the browser itself. Other browser still works. Completely closing all tabs and restarting Firefox gets it working again, but dare I reload the previous session again, open all the tabs (acts like it's going to work), but then loses connection.

My firefox browser is completely unable to load any tabs. The search bar works but screen remains blank after pressing enter, I have tried uninstalling and reinstalling with no change. Thank you any help

~~~SOLVED~~~ Hello guys, this is about some..adults sites, i'm just getting loading error on the screen. Sorry if that's inappropriate. Also recently, youtube videos can't play at 1080p, only 720p, even tho i know the video it's 1080p.

Hello,

I have been using Firefox for something specific for a long time now. I've noticed in a recent update having the ability to do what I need has ceased. If a Firefox window is covering another (or covered by another program) on the screen, the graphics of the background Firefox window no longer update. I run a software that needs to see these graphics in order to function properly.

Could you tell me which version this stopped working and if there are plans to reverse whatever change you made?

Thanks, Kyle

When I do a search using google, and then click on a choice (one of the first sites listed) my browser tries to go to something called "googleadservices" and it will not load. Just hangs up and gives me a blank page. How do I stop this or remove googleadservices?

I use two displays, suddenly it is no more possible to move the Firefox- and/or Thunderbird-Windows from Monitor to the other monitor, grabbing its mainbar and trying to move, the window sticks on half way and then flops back.

Hello, i facing the problem that firefox goes to infinite update that never end. This consumes my CPU a lot higher that usual (even often reach 100%). I'm tired of this problem that i many time reinstall and refresh(reset) the firefox

Error message when accessing business websites which use Cloudflare: "ERROR 1005 ACCESS DENIED DUE TO ASN 9009". This seems to be because Firefox is using ip addresses which are blacklisted. This has been checked with blacklist services such as DroneBL. I am not using a VPN. I constantly clear cache & cookies from Firefox and then restart the computer. I am not ignorant or stupid. Why is Firefox using blacklisted ip addresses? Is it because of M247? Is there any way around this extremely annoying problem? Thank you for your response.

FireFox Developer 99.0b8 (64-bit) on the "aurora update channel" on Windows 10 PC (version 1803, build 17134.2208)

I notice whenever an update is pending (the green dot appears in the icon for the "Open Application Menu"), FF becomes unresponsive in a way. When it happens: It does not totally freeze. I can select/switch between existing tabs & scroll thru their pages. I can close tabs. I can open a new empty tab. But I can't load or refresh any pages. The only fix is to do the update, and re-launch.

Since the developer edition gets updated frequently, it is a pain.

I like the Developer Tools! But... How can I scale back the FF "update frequency", or "change the channel", so updates are, like monthly at most?

thank you.

I saw this post https://bugzilla.mozilla.org/show_bug.cgi?id=542690 where it seems implied that it should work, but on LMDE 5 w. firefox 98.0.2 64-bit scrolling horizontally w. touchpad doesn't work for scrolling on pages nor for scrolling the tab list at the top.

I recently upgraded graphics cards from an Nvidia GTX 1080 to an AMD 6900XT. Since then I noticed video stuttering on YouTube while playing 4k videos, especially noticeable at 4k/60FPS (example video ). Prior to the upgrade, I was not experiencing issues.

I monitored task manager as the video was playing to see CPU usage, which was sitting at 25% (4 core 8 thread CPU). GPU usage was fluctuating from 1-3%.

I tried resetting all the changed configuration options in about:config, removing all add-ons, "Refreshing" Firefox, and ultimately uninstalling and reinstalling. Nothing has worked so far except for "Troubleshooting mode" in about:support. In that mode, I experience no stuttering and GPU usage rises to 25-35% with the video playing, even before I reinstalled.

This most likely isn't a networking issue as the "Stats for nerds" option on the YouTube video shows I have 10-20s of buffer while the video is still stuttering.

I would like to find out what's different about Troubleshooting Mode that is not giving me the same problem while in "Normal Mode". Any advice?

Whenever I try to sign into Outlook Webmail (https://outlook.office.com/), Firefox crashes. I am on a MacOS Monteray (12.2.1). I have cleared all Firefox caches and cookies. I have completely uninstalled and re-installed Firefox. I have run it with my usual extensions, and completely clean, without any extensions and just the default settings.

The initial login page loads fine, and I type in the email address associated with the account. This takes me to the password page. If I type in an incorrect password, the site tells me so immediately. If I type the correct password, Firefox crashes--I get the spinning beachball cursor and (application not responding) in the dock. My only recourse is to force-quit Firefox.

Outlook webmail used to work fine in Firefox--I used it on this very machine nearly every day. The only change was that I recently had to update my email password. But again, I have had to do that every three months for years and have never had any problems.

Outlook webmail works just fine on this machine in Safari and Chrome. It's only Firefox that has any problems with it.

Any ideas about how to fix this would be greatly appreciated.

I can't play a video when logged into a website - see https://support.mozilla.org/en-US/questions/1371380

I'm sure it is not Firefox as I have also tried Chrome and Opera; same problem. How can I debug this and find out why the video cannot be played ?

I see there is 'Remote Debugging' and 'Browser Console' under 'More Tools'. How do I use these or other tools to find out what is causing the problem please ?

For the past several months, I've had increasingly worse graphical errors on Google Drive. At first it was only in a few documents, and now it's in every single document. These errors only occur on Firefox, no other browser. Text that I type is constantly blurry, oddly-sized, or oddly-spaced, with some letters touching while others have large gaps between them. I've also had some other small issues, like the document thinking that I'm two people and asking me if I want to see "the changes made my collaborators" when I'm the one currently typing (the documents aren't shared with anyone else, and there are never any changes beyond the ones I make), or showing my cursor highlighted with my name as if I were someone else watching myself type. It's made it more difficult for me to focus on work and I don't know what to do about it.

I've tried the following methods (most of them multiple times over the past months) to solve it, none of which worked: - Running the windows in safe mode - Uninstalling all add-ons and themes, clearing cookies and cache, and then restarting my computer - Uninstalling Firefox entirely, restarting my computer, then reinstalling it - Refreshing Firefox - Looking through pages like Firefox Task Manager and such (although the information there didn't really mean much to me, nothing looked out of the ordinary)

Does anyone have any ideas about what I can do about this? I was ignoring it for a while since it's still legible, but it's become really annoying, especially when it makes some words hard to read. Thanks in advance for the consideration. Here's a screenshot of a document with the weirdly-spaced, blurry text:

Greetins, There are times when I can not use google to search things, it kept telling me "Server Not Found". Although accessing the web directly worked. I tried to googling on another browser, and it worked just fine. Any idea why/what might cause this? I never touch firewall settings so everything should be on default settings. Thank you
