Diễn đàn hỗ trợ Firefox

I am having Firefox crash on startup much like Firefox Desktop crashing on startup, initially in version 140, but I have downgraded to version 139 in my troubleshooting and I'm getting the same symptom.

It is frustrating that this does not seem to leave any records in the Windows event log or the Firefox crash reports, and that the fact that there's a known issue of this severity is rather hard to find.

I reinstalled Firefox I am trying to open the program in windows 11 it does not work I can still open it in administrator mode but then I cannot type anything in the search box I cannot browse to any websites or web page I cannot connect to the Internet through Firefox.

i have uninstalled, reinstalled many times. I cannot load the program once it has been uploaded to my laptop. always get error that it cannot find the URL. ICON shows up on desktop but clicking on it just brings up that error.

Desde que he instalado Macos Sequoia 15.4.1, Firefox no consigue abrir ninguna ventana de internet. Internet funciona porque con Google Chrome o Safari sí que puedo navegar.

Hello! I am an avid user of firefox (especially with adblockers) on a windows 11 PC. Unfortunately, I have recently been experiencing an issue where when I attempt to open firefox, a window will open for a split second before instantly closing again. My PC is up to date, I have tried refreshing firefox and doing a clean install, but cannot seem to overcome the issue, or even open it in safe mode. Does anyone have any advice? Many thanks in advance!

I normally put the computer to sleep at night, rather than powering down (although I do that periodically). After waking the computer, and clicking Firefox open, the browser loads with the two or three tabs I last had open, and within the minute closes. There's no warning or pop-up window saying what happened. I open it again, and within the minute it closes again. This happens four times. On the fifth try, Firefox opens without the previous tabs and with just one "New Tab" showing. After that it's fine. Also, it doesn't happen if I wake the computer and let it sit for a while before sitting down.

This is an oddity that I can live with. I'm just curious about what's going on.

Thanks, Ed LeRoy

Whenever I close Firefox and try to reopen it, it brings up a system error that says, "The code execution cannot proceed because C:\WINDOWS\system32\pmls64.dll was not found. Reinstalling the program may fix this problem." I've tried completely deleting Firefox and reinstalling and it opens a new tab, but when I close it i get the same error message.

I can not open my firefox browser. I never had this problem before. When I click on the icon I have on my bottom of my computer it says I can not get on it says many different error messages being sent. I am not a computer whiz so what should I do? should I uninstall it and re-stall it? would I loose everything I have book marked. HELP

Hi, The browser suddenly closed, and I can't open it since then. I searched for what to do but couldn't find anything helpful. I tried reinstalling Firefox, but it still doesn't work. I don't know it is a helpful information, but the other browsers (like Chrome and Opera) also don't open.

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.

Firefox launch opens /home/pdl/Documents/Browsers/Firefox/chrome as a new tab, I have set the setting "Open previous windows and tabs" on and off, I prefer this setting to be enabled, my OS is LMDE 6 and Firefox is the flatpak install version 137.0.2 (64-bit), I have also tried the system install and deleted all Firefox in between installs or should I say I think I did, please this is driving me nuts, even with me logged out of Sync this happens.

Thanks
