Firefox Support Forum

I have been getting a message that says firefox has something running and cannot shut down. I went into task manager and 'shut down' firefox, but the message keeps on coming. I then thought that I would uninstall it and then reinstall, but it tells me that it cannot uninstall because it is running, -"Firefox is already running but is not responding. The old Firefox process must be closed to open a new window." When I click on ' Close Firefox' nothing happens. when I click on 'Cancel' the message disappears, but will reappear. Then in desperation, I went into program files and deleted the Fifefox folders but it wouldn't reinstall. There is obviously somewhere a file/file which is screwing me up, does anyone know what this it?

Hello, I have the fallowing issue with Firefox and the sound icon on taskbar in Windows 10 22h2, when Firefox is open and I click on the sound icon on the taskbar in Windows 10 22h2 the sound icon does not open, when Firefox is closed the issue is gone.

Any help to fix this issue would be great.

Thanks

Hi,

I recently facing an issue that the Firefox browser randomly maxed out my RAM and went unresponsive. Like the screenshot below, I am only trying to open Facebook and Instagram, 2 tabs.

I have tried to open about:memory and about:processes to monitor but it just went unresponsive and both the monitoring just hanged.

Have no idea why the Firefox process taking up so much RAM. Need help.

I've followed all the recommendations. Problem still happens in troubleshooting mode as well. Doesn't allow sign in either. Have reloaded all C++, uninstalled, reinstalled, restarted. No links or pages will open.

This isn't the first time this has happened. After each occurrence, I have to completely uninstall the browser and reinstall it from scratch. This means I have to reopen all my tabs, which is very annoying. In Chrome, I have had a large number of tabs open for many years and it works fine.

With Mozilla, something terrible is happening... I have many tabs open in Mozilla, and there comes a moment when, upon launching the browser and opening two or three tabs, Mozilla starts consuming up to 10 gigabytes of RAM. If I open a few more tabs, the browser crashes. I don't need to open 50 or 100 tabs, just 7-8-10 tabs are enough to make the browser crash. Moreover, if I open a new tab and go to google.com, the browser takes a very long time to load, even if it's the second tab.

This problem has happened before. I don't do anything with the browser, just visit sites like YouTube.

Clearing the cache and other recommended actions do not yield positive results. This is very annoying. Mozilla is my first and favorite browser, which I have been using for almost 20 years. I wouldn't want to uninstall Mozilla.

The following error keeps happening constantly in Firefox ESR 52.9:

Description Faulting application name: plugin-container.exe, version: 52.9.0.6746, time stamp: 0x5b2bc061 Faulting module name: mozglue.dll, version: 52.9.0.6746, time stamp: 0x5b2bbbde Exception code: 0x80000003 Fault offset: 0x0000fb33 Faulting process id: 0x0x35F8 Faulting application start time: 0x0x1DAA06C630DBB2E Faulting application path: C:\Program Files (x86)\Mozilla Firefox V52.9 ESR\plugin-container.exe Faulting module path: C:\Program Files (x86)\Mozilla Firefox V52.9 ESR\mozglue.dll Report Id: 1e159f0c-62cf-4695-8ef2-861f89c36041 Faulting package full name: Faulting package-relative application ID:

Any ideas what is causing this?

Thanks!

For a few weeks now, FIrefox will not play DRM content video on this computer. I have tried all the suggested solutions and none have worked. Also, I uninstalled and reinstalled Firefox, but the problem remains. I am very frustrated with this problem and am ready to get rid of Firefox permanently on ALL our computers unless this can be fixed.

Thank you in advance for your assistance.

I have both speakers and a headset on my desktop. The system has worked fine for the past 1.5 years. Suddenly today, when I unplug by headset and select speakers for audio, it works for other apps, but not on Firefox browser. Can someone offer some possible reasons for that and, even better, as solution?

Site (https://www.pinerolo.news/

The animated images of the articles are loaded once every 3. On Chrome Android I have no problem.

I solve it manually by resizing the page, so they load.

Where could the problem be? In the animation of their site? Do you have any advice on a fix?

Hi Friends.... This morning logged into my website as usual and this message appeared on the home page. I have not checked the link as it seems potentially malicious ... It does not appear when visiting my site on Safari. I have emptied the cache I have been through troupbleshooting mode I have reinstalled Firefox and it still is there..

How to rid myself of this

Hi everyone,

I'm running Firefox which I compiled with vaapi support because I was trying to use hardware acceleration for videos, so I think this bug may have something to do with that. Every time I open a pdf file my browser instantly crashes. When I use troubleshoot mode I have no such issue. I then tried with a fresh all-default user profile with no add-ons, nothing, and still I crash when loading a PDF. Any pointers would be appreciated.

Sometimes I find that Firefox just randomly closes on my laptop, usually when I step away for about 10-20 minutes. I can't find any info in the about:crashes page when it happens.

I have been using Firefox as my primary browser for a very long time. Now, every time I start Firefox, I get a message that the update failed, and that I should manually download the update file and run it. I do so, the update appears to work, and Firefox behaves, until I stop it and restart again. Then I get the same message. I looked online - it appears that others have had this problem, but no clear solution. I am not willing to use Edge, but am beginning to wonder if it is time to leave Firefox. I would appreciate a solution, preferably a reliable one. Thanks, Joe Purvis Email hidden for privacy reasons

I keep getting this message that pops up in a private window to restart to keep using firefox. Everytime I click restart Firefox, it closes my tabs and opens them again. However, 5 minutes later the window pops up again. Even after repeated attempts of updating, even doing a full restart on the computer, Firefox continues to send this window to me. The private window in the bar says about:restartrequired.

I've tried uninstalling Firefox with a fresh install as well as doing a Refresh of Firefox. Neither seem to solve this problem.

My Windows virus protection shows nothing but I keep getting notices int he lower right corner of my screen that say Mozilla Firefox ESR and tell me there is an infection. It tries to take me to a website to scan and then buy McAfee to fix it. If I make sure Firefox is shut down (forced through Task Manager) it seems to go away. It appears that only the Firefox browser may be infected.

Firefox takes about 5 minutes to load every it launches, before working smoothly like it should. This problem occured first time yesterday morning, and I have no idea what could have caused it.

It happens :

• when I launch firefox normally (whatever the profile)
• when I launch it from the terminal (it provides no output at all)
• when I tell it to launch the Profile Manager (5 minutes to see the Profile Manager appear, then 5 more minutes to launch firefox using the selected profile)

It does not happen :

• when I click "New Window" inside an existing firefox process
• when I call `firefox --help` from the terminal

Here's what I've tried :

• First, I've seen pretty much every article from Mozilla Support, Reddit or SuperUser (writing this question is kind of my last resort)
• I've tried removing and then reinstalling Firefox from Flatpak, from the Fedora repos (using `sudo dnf install firefox`) and using the manual install via the archive (v125)
• I've tried downgrading firefox (when using the package manager install) from v125 to v124
• I've also tried the Firefox Developer Edition, same problem here
• I've tried using the "Refresh Firefox" feature and restarting in Troubleshoot Mode (both are also affected by the slow startup, which makes them particularly painful to execute)
• I've tried manually deleting the `~/.mozilla/` folder (= manually deleting my profiles)

When firefox launches, it does not freezes my OS and does not seem to use many system ressources : CPU usage is normal, RAM as well, and it does not seem to read many things from the disk as well (I've seen some threads where this was the issue).

And here is something interesting that I discovered :

• loading (including refreshing) `about:profiles` is also slow and this time freezes firefox (OS reports it as not responding, I can't switch tabs and I can't see my mouse). Other about pages seem to work fine (although I did not try them all)

Thanks !

PS : Even if I think it has nothing to do with the issue, I prefer to mention it here : I was messing with virtual machines yesterday when the issue occured for the first time. My disk got full at some point and I don't know but it might have messed with firefox. At this stage, I had not deleted any files that could relate somehow to Firefox, that's why I doubt it would have caused anything harmful to Firefox. (instead, I mounted an empty partition from my disk to get some space)
