After Firefox updated today, the executable no longer starts. I get the following error message:

firefox.exe -- Bad Image

C:\Program Files\<Mozilla Firefox\gkcodecs.dll is either not designed to run on Windows or it contains an error. Error status 0x000000d. </p>

And then another error message: Couldn't load XPCOM.

Please advise.

Can’t launch Firefox 3.5.19 on Linux Ubuntu When trying to run with:

./firefox

Terminal gives the following:

./firefox-bin: error while loading shared libraries: libdbus-glib-1.so.2: cannot open shared object file: No such file or directory

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!

For about one week (or more) results of my questions or other input have resulted in suggestions/sites in Spanish. Yes, I live in South America, but I do not speak or read Spanish. I have chosen English as my preferred language. What's up?

Hi, We are using Horizon VDI terminal server. Firefox is installed on these servers. Some users get Firefox is already running but is not responding error. Ending Firefox via task manager does not work. I log off the user and have them log in again, but it does not work.

When I check, I see that the user's profile file cannot be created on any terminal server.

Is there a solution to this problem?

Getting the XPCOM can't load message. Uninstalled everything and reloaded firefox. I could not get it to work. Seems to be a lot of misinformation on the subject (irony here). Finally loaded the latest BETA test version problem solved ... for 2 days. Got the XPCOM message again. This time I reloaded the latest BETA test version and disabled updates. Pretty lousy solution but at least it has been trouble free for over a week. SHEEEZ!

I'm trying to install Firefox on my work computer (ARM64 version), but when I do I'm getting the crash report window at the end of the installation process (multiple times in a row), if I try to open the browser (only once), and during the uninstallation process (also multiple times in a row). I've tried a clean reinstall multiple times, including deleting the folders from program files, %APPDATA%, and all registry entries I could find (HKEY_CURRENT_USER>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE, HKEY_LOCAL_MACHINE>>SOFTWARE>>WOW6432Node).

I've contacted IT and they don't seem to think anything pre-installed should be affecting this. I'm unable to get a crash ID as I'm unable to even start the browser - all I get is the Firefox crash reporter, immediately. Is someone able to help me figure out why I can't get this working?

I originally deleted Firefox by accident and have downloaded it via Microsoft Store. All seems well then after I click on the app to open it, I Get the ‘Windows cannot find C:\Program Files\Mozilla Firefox\firefox.exe. Make sure you typed the name correctly, and try again’ for ‘Firefox’ error how can this be corrected?

There is no Japanese in the language to which the website is translated. It is understandable that Chinese is available in the Asian region. However, we would like to ask why there is Indonesian, Vietnamese and Korean, but no Japanese.

Hello, today I could not launch Firefox on my Mac. Because this is a corporate machine from Kyndryl, I downloaded from Kyndryl App Store, I have rebooted the systems, I have updated iOS to last version, but still haven't solved the issue. This is the situation: Firefox is installed, I click to launch it, I am asked to authenticate with MFA I authenticate correctly, and Firefox just sits at the dock bar jumping, then stops jumping, and nothing else happens. I repeated the process several times, made several reboots, nothing changed. Can you suggest a solution?

Is there a way to make the URL high lighting of the domain more obvious? I find that most people can barely see the highlighting and I'd like to make it obvious (bolder and red, or highlighted in yellow, for instance.)

Can this be done via userchrome.css?

Thanks,

Thane

Ever since the latest update, whenever I right click the Firefox icon in the pinned tiles on the Windows Start Menu, the options to launch a new tab, new window and a new private window don't show up. They show up when I pin Firefox to the taskbar but not the Start Menu.

Images attached for illustration: right-clicking Firefox in Start Menu and right-clicking Firefox in taskbar

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.

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?
