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.

All my other browsers work fine but since April 4, 2025 Firefox won’t work at all. Websites won’t load. I have tried to clear my cache & cookies, I have checked my connection settings, I have checked for malware, I have turned off all my extensions and I have completely restarted my computer several times now, nothing has worked. I also did trouble shoot mode & reinstalled Firefox (though I will admit I maybe didn’t do this step properly). I refreshed Firefox. Why is it not working? What happened? I don’t know what to do as I don’t want to lose all my bookmarks and passwords that I have yet to move over to my password manager. Please help.

I have synced Firefox on my wife's iPad and can see all of her saved Firefox passwords OK however when she goes to password protected site she is unable to enter her password I don't anything about Ios I have been a windows / android man from day 1 and 76 years old

I don't know why but there are very thick bezels on the right, left and bottom of the web view when I enable vertical tabs, especially when minimized. the bezel is not clickable or touchable. and it will stay like that on almost all websites (except settings), i need help, this is very annoying

I needed to remove and replace my Firefox browser. In the original browser, I had a list of items on top of the browser with several things including "Bookmarks" which I could access. Now that I have reinstalled Firefox, that listing is no longer there. If I am making sense, can you tell me how to get them back on top? Cy

Hi there,

I'm experiencing a theming issue when using Firefox (flatpak) on Hyprland with a pure black (#000000) theme applied via a theme extension. When the Firefox window is out of focus, everything looks fine — the background is truly black as expected. However, when the focus is on the window, the blacks turn washed out grey, losing the #000000 appearance. This doesn't seem to happen in other apps and I don't seem to have any filter for the focused windows (except for borders), so it seems related to how focused windows are handled in Hyprland or how Firefox draws its content under Wayland - have you heard about this issue and could you help me diagnose it + find a solution? Is there a setting I could tweak either in Hyprland, Firefox, or GTK/Qt config to prevent this color shift on focus? Thanks in advance!

My Firefox keeps going down in my lower bar,it doesn't shut down or turn off it just keeps disappearing down in my lower bar and i have to click on it again to open the window back up on my desktop,it happens alot like several times while i'm doing anything and makes it difficult to do anything,like when i'm filling out applications my firefox browser just leaves my desktop and goes down into my lower bar and i have to click on it to bring it back to my desktop,i don't loose anything like when i'm filling out applications thank god,this has never happened to me before for all the years i've been using firefox,it doesn't happen at all when i open up my Microsoft Edge,how can i fix this without having to get rid of the browser and downloading it again and possibly losing all my bookmarks? Thanks for any input to hopefully resolve this issue. Bill

a couple of months ago FF suddenly stopped reopening the last session and instead opens always the same from a specific date. performance has been poor to the point that I can barely browse FB anymore. cleaning temp files didn't help. what's the best way to go about it? is there a way to export the history before doing a refresh or new profile? thanks
