Add-ons in Firefox on Windows 11
I'm a recent reluctant user of Windows 11. I can't get Firefox configured the way I like it on the new Windows 11 machine. Every single time I try to find an extension, I get a message "Gah. Your tab just crashed." I've tried the Restore This Tab option to no avail.
I uninstalled Fx, downloaded a fresh copy (using Edge, ugh) and installed it. I get the same result.
I had Fx running on the Win 11 machine, before I foolishly accepted an upgrade that took me to Win 11. I suspect that there might be a corrupted Profile or other vestige of that Firefox installation that is causing problems. (Or, because I used Edge to download MSofat hacked me.)
Can someone please tell me how to find and remove all vestiges of Firefox? I want to get back to a fresh slate and try again.
I'm posting this from my old and slowly dying HP laptop running Windows 10. Fx runs here, but the system is slower than Christmas to a 9-yo.
TIA

We're sorry to hear that Firefox is crashing. In order to assist you better, please follow the steps below to provide us crash IDs to help us learn more about your crash.
The crash report is several pages of data. We need the report numbers to see the whole report.
- Enter about:crashes in the Firefox address bar and press Enter. A list of Submitted (and Unsubmitted, if any) Crash Reports will appear, similar to the one shown below.
- Copy the 5 most recent Submitted Report IDs that start with bp- and then go back to your forum question and paste those IDs into the "Post a Reply" box.
Note: If a recent Report ID does not start with bp- click on it to submit the report.
(Please don't take a screenshot of your crashes, just copy and paste the IDs. The below image is just an example of what your Firefox screen should look like.)
Thank you for your help!
More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.
Does it still happen in a new profile? An easy way to test a new profile is to install Developer Edition and see if it happens there or refresh your existing profile. Make sure you stay signed out of your sync account when testing.
@Paul - unfortunately I cannot copy the information requested. I tried to go to Mozilla Support on the Win 11 laptop and got the exact same screen message. I tried to enter 'about:crashes' and got a response saying "No crash reports have been submitted.
@zeroknight - I'll give that a try but I'll have to download it using Brave
A tab crash (Gah. Your tab just crashed) can be hard to troubleshoot as you may not get the crash reporter.
You can create a new profile as a quick test to see if your current profile is causing the problem.
See "Creating a profile":
If the new profile works, you can transfer files from a previously used profile to the new profile, but be careful not to copy corrupted files to avoid carrying over problems.
