I use translation A LOT. (I'm learning a foreign language.) It would help to be able to move or resize the results window. Right now, it covers the original foreign language text. I want to compare the translation with the original text and the fixed size and position of your results window makes that a lot more difficult.

Lately every time I open Firefox on my PC (Win 10) it says that it is already running and that I need to close it first. How can that be if I just started the computer session?

I keep getting the error message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." I have tried to close it using Task Manager as recommended in the help article, with no success. I have uninstalled it and even run the refresh instead of removing it, but still nothing. This is the second computer I am receiving this error message on, so any suggestions? FT

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?

sINCE 36 HOURS AGO WHEN I START FIREFOX I GET AN ERROR SAYING Firefox is already running close the application or cancel I choose close and i get the message over and over if i choose cancel nothing happens the task manager show FireFox (3) running and my only way out of the look is to end task I was fond of firefox but there seems no way out of this conundrum

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!

Hallo, ich habe am Mittwoch 26.02. das Programm PC-Cleaner gestartet und unter der Funktin "Optimieren" WINDOWS - Reparaturprüfung aktiviert. Das Programm lief ein paar Minuten, dann erfolgte ein Neustart, danach wartete ich sehr lange und es passierte nichts! Ich habe nach ca 1 - 1,5 Std. die Task abgebrochen! Wollte dann meinen Browser Firefox öffnen, was nicht mehr ging!!! ...genau so war es mit PC-Cleaner! Ich habe mich dann an den PC-Cleaner Support gewandt aber über den Chat nicht viel erreichen können! Ich wollte das gerne telefonisch klären - war aber auch nicht möglich! Nun habe ich auf die Rückmeldung eines Technikers gewartet! Mittlerweile konnte ich das Programm PC- Cleaner erfolgreich löschen und neu installieren! Aber mein Browswer funktioniert noch immer nicht trotz mehrfacher Neuinstallation! Ich kann Firefox öffnen allerdings nur als Admin, sehe dann meine Lesezeichen, kann aber keine Seite öffnen! Bitte info - Vielen Dank!

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?

Firefox will not open in my Windows 11 desktop; is Microsoft playing games with non-Microsoft applications or is there a problem with my browser? fresh install does not help! last week I had to reset Windows 11 because nothing would open in my desktop...... reloading all my application is not near the top of my wish list having already done it twice! all the Microsoft stuff opens fine; even my copy of Office 2003?

The shortcut icons on my home screen used to direct me to frequently used websites. Now shortcuts are showing up linking to to recently used websites, pushing off or even removing the ones recently used. I can't find anything in settings to remedy the problem so I have disabled home screen shortcuts. Do you have a patch to correct the problem?

My firefox app on my windows will not start. I have removed and reloaded several times. Sometimes it works but as soon as I turn off my computer and turn it on later, it will not start
