Firefox Community Forum

I have Firefox installed and pinned to the taskbar. When I click it, it immediately goes to a download Firefox page instead of opening. I then open another tab to get into g mail or anything else. I can then close the download tab and continue. This is most annoying. I tried uninstalling and reinstalling which works but then lost all bookmarks and the answer there was to go to old Firefox and restore, which I did and that worked , however, the download page came with as well and this time in a different more colorful version that is quite long.

Hello,

I am looking for help with a Windows 11 Pro 24H2 system. Firefox no longer works despite a clean uninstall and reinstall, including deleting all related folders.

When I reinstall Firefox, the error appears, but the application still manages to launch. However, after a system restart, the issue comes back.

When launching Firefox, I get the following message: “Firefox.exe failed to start correctly (error 0xC0000022).”

I can’t find any recent information about this issue. Thank you in advance for your help.

Hello, I have installed the latest Firefox on my Windows 11 desktop PC. I have created a shortcut to Firefox in the start menue Since a few week, I observed that I had to invoce Firefox twice in order to get is running once. The same happens if I double-click on firefox.exe in the intallation folder (C:\Program Files\Mozilla Firefox): After the first double-click, the windows activity circle appears for a few seconds and then dissapears again (without staring Firefox). After the second double-click, Firefox starts immediately.

I can repeat this several times.

• first double click > nothing happens
• second double click > Firefox starts
• closing Firefox
• third double click > nothing happens
• fourth double click > Firefox starts
• closing Firefox
• fifth/seventh/... double click > nothing happens
• sixth/eigth/.. double click > Firefox starts

I have no idea what might have gone wrong. Any suggestion from the community is appreciated. Best,

I'm a Mac user on desktop. Something happened to my Firefox about two weeks ago. I was able to bring up Firefox which had all my bookmarks, passwords, etc. What is different is that I can not bring up Firefox by hitting the icon in the dock. If Firefox is already up and I hit he icon, it will jump to the front. But not if it is sitting in the dock.

I am unable to open my profile on Firefox. I am using desktop and windows 11. I am typing this question on DuckDuckGo browser because I was unable to go in. It will not let me search, open new tabs, refuse to open new tabs and even to click on settings. I also tried to delete it in an attempt to log in again but it won't even let me delete it. The image I shared is all I see. No bookmarks, shortcuts, ways to do settings and other things. Thank you!

Hello,

I updated Firefox on Mac and was prompted to install a helper and now Firefox will not run. I've tried several times. I uninstalled Firefox and tried to reinstall but when I try it doesn't work.

Thanks.

Actually this is just the only route I could figure out to your page where I had PREVIOUSLY asked this question and was checking back in to see whether 'the Community' had given me an answer yet. I'm no doubt IMPATIENT since my bank told me I need you, not Google and Microsoft Edge , who I both HATE for coming on to MY laptop, asking for more information sharing and basically DEMANDING I follow their marketing instructions since they had somehow REMOVED the X at the top right corner and simultaneously BLOCKED my access to and use of my OWN laptop, so that each time I have NO OPTION but to turn off the power on my laptop, to "reboot" as they once said. If even a basic, ancient telephone can be HUNG UP on scammers.....forgive me. I REALLY want to use your search engine, as WELL as your site. Please advise.

Firefox is already running old Firefox must be closed. I have tried everything in the help menu. delete parent.lock , restarting etc. nothing is working. I can create new profile but i cant find any toolbar, bookmarks etc please help

Starting yesterday, browsing to the ebay.com url resulted in Korean language text being displayed per the attached screenshot. The same continues today. I tried the ebay options of changing language by choosing a national flag. Choosing the US Stars and Stripes made no difference; I still got Korean text. I tried disabling my VPN; it made no difference. I tried choosing the Canadian Maple Leaf flag and got English text but Canadian prices.

I tried to report the problem (in Firefox) using ebay's contact links; but those links require logging in. I could not because I could not pass the Capcha challenge while remaining in Firefox.

Thinking that the problem might lie with Firefox, I loaded and used the Brave browser. Not only did I get US English and prices straightaway, I was able to login with ebay and report the problem. My VPN is active and has been since I loaded Brave.

Because I have these problems only while using Firefox, I came here to report the problem and ask for assistance resolving it.

Hi,

I have a laptop with an AMD Ryzen 7 8845HS CPU, including a Radeon 780M iGPU, running Ubuntu 24.04. In order to fully utilize the GPU by supporting OpenCL acceleration I installed the additional drivers by: `sudo amdgpu-install --usecase=graphics,multimedia,opencl --opencl=rocr --opengl=mesa`

After that programs which benefit from OpenCL acceleration recognize the GPU, however firefox starts crashing with the following error msg:

XPCOMGlueLoad error for file /usr/lib/firefox/libmozgtk.so: libwayland-client.so.0: failed to map segment from shared object Couldn't load XPCOM.

It seems that the AMD GPU drivers registered their libraries in `/etc/ld.so.conf.d` as 10-rocm-opencl.conf, 20-amdgpu.conf which means that libraries within the given folders are found first.

This applies to the libwayland-client library, which is used by `/usr/lib/firefox/libmozgtk.s`:

ldd /usr/lib/firefox/libmozgtk.so | grep amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007013767bf000)

Interestingly the same `libmozgtk.so` library is used by thunderbird:

ldd /usr/lib/thunderbird/libmozgtk.so | rg -i amd libwayland-client.so.0 => /opt/amdgpu/lib/x86_64-linux-gnu/libwayland-client.so.0 (0x00007d44b0f41000)

However thunderbird just works fine, so I expect that there might be something wrong with firefox utilizing this library.

Maybe I should also mention, that I'm not even using wayland as desktop compositor, but good old x11:

echo $XDG_SESSION_TYPE x11

Is there any way to further debug this issue?

I had two profiles, was in the process of trying to learn how to use the 2nd profile (as seen in the link below), which I still have no answer for. Somehow, maybe I held down SHIFT for too long and clicked on something by accident, idk, but somehow, I ended up REFRESHING the 2nd profile, causing it to delete everything I had done with it, and it backed up the old profile onto my desktop in the process. I figured I could just simply delete the new profile folder it had created and put back my old profile in the profile folder, but now, Firefox will not open at all, saying "Your Firefox profile cannot be loaded. It may be missing or inaccessible." How do I get it to recognize the profile folders again? OMG, I'm using Microsoft Edge, please, get me out of this!

I have this message after returning from nightly version to the stable one: ``` Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing Firefox profile. To protect your information, create a new profile for this installation of Firefox. ```

Sometimes when I do a google search the results come up in a foreign language! I am in the USA and speak only english. Changing my preferences doesn't always maintain the fix.

Every so often for the past few days this "unfinished" program window has appeared on my pc on top of a normal Firefox window (see attached png). Does this have something to do with Firefox? I think the same thing appears when I first open Firefox, then it gets "filled in" and appears as a normal Firefox window. I am running Firefox 133.0.3 (64-bit) on Windows 10 Pro Version 22H2 build 19045.5247 Windows Feature Experience Pack 1000.19060.1000.0.
