Firefox will not open after downloading your latest update. An error message comes on screen: The file directory is corrupted and unreadable. This is occurring on a windows11 pc. I can open other files thru the microsoft browser. I'd appreciate some help, thanks, Gary

Running Firefox on macOS Sequoia 15.0. Afternoon of Tuesday, 8 October, Firefox abruptly ceased loading any pages. I eventually learned of the malware incident and downloaded Firefox 131.0.2 last night and overwrote the existing file. It worked for a brief moment, then also ceased functioning. Have downloaded 131.0.2 several times now, with no further success. Currently dead in the water with Firefox, and stuck with Safari. :(

I am using windows 10 and since the last update I noticed a duplicate firefox icon is opening everytime I clicked on the main firefox icon. Attaching a screenshot.

I can't launch Firefox -- has never happened. I just need quick fix - don't have time to learn as I have Dr. appt. to get to! Got error msg.: re whatever update sent today was not compatible with whatever I already have, but I didn't write down the numbers -- they were identical, just new and older version.

What's the recommended way to update the product globally across Windows and Mac? This would include users with various versions installed but I would rather not download each. Is there a single update command that could be run without user intervention?

Windows 11 home computer with Mozilla Firefox version 122.0 from 1/23/2024 cannot be removed even in safe mode. When attempting to remove there are no errors, it just fails to go to next step when select uninstall. This version will result in a pop-up error of 'Couldn't load XPCOM.' A later version of Firefox worked with no issues. When the user accidently selects older version or at random times without user interaction the pop-up error appears.

Have not attempted to edit the registry.

Suggestions for steps to remove so a current version of Firefox can be installed would be appreciated

Thank you

Whenever a new version of Firefox is installed the number inside the parenthesis increments by one.

I was wondering why this number is there in the first place.

An example would be when you go to a shortcut for firefox, what you see is something like Firefox (x), x being a number. In my case it is 60. Firefox(60).lnk and if I try deleting it, I am then asked if I want to make it Firefox (61).lnk

Last February, I installed an update that wasn't compatible with my macOS 10.13.6 High Sierra. As a result, my bookmarks disappeared. For a long time, I've been getting popups on a daily basis, and sometimes twice daily, telling me to update again. Based on my last experience, I not about to install any more updates. I want these messages to stop.

Firefox 64-bit installed to a completely new installation, but did not update my existing 32-bit version.

How can this update to the 64-bit version be done and still retain all of the tabs, favorites and saved data already in the 32-bit version?

Please advise. Thank you.

Important update! On March 14, 2025, a critical root certificate in Firefox will expire. If you’re still using an older version (before Firefox 128 or ESR 115.13+), it’s crucial to update to Firefox 128 or newer to avoid issues with add-ons, DRM-protected content, and other features.

For full details, check out Update Firefox to prevent add-ons issues from root certificate expiration.

I keep getting a message on facebook stating my browser(Firefox) is no longer supported even though it is updated to newest version....i have cleared cache and cookies and I still get the same message on facebook. (See attachment screenshot).

Firefox appears as a different application on the Taskbar with some default icon (not the Firefox icon). This happens regardless it is started from the Start Menu or from the pinned Taskbar icon.

This behavior appeared recently, I used Firefox for years on this PC without this issue. I guess it is caused by an update (Windows or Firefox).
