I get scam messages that say "Trojan virus detected!" on Mozilla Firefox which I cannot delete. I have run antivirus scans which show there is no virus or malware. I have shut down the desk top. How can I go to reinstall Mozilla Firefox default settings or do you have another solution?

I love Firefox and have used it forever. But its memory usage is killing me lately and I'm seriously reconsidering.... PC, Win11, Intel7, 16GB memory. (I'm typing this from Chrome)

I've updated, restarted, but it keeps maxing out and slowing my computer to a crawl. Somebody please tell me there's a fix pending?

I am getting a report from Firefox when I run the install that it can only run on Windows 10 or Windows 11 and since this is a brand new win 11 computer that has never had any other OS on it, I do not understand the report.

What can I do. Chrome and Edge had no problem loading. I plan to install Brave next.

Firefox is my primary browser.

I receive this Error msg trying to access Settings option in the AJC epaper section https://editions.ajc.com/shortcode/AJC412/edition/f117d96a-c78b-4df3-4b6a-0e587f6cfd22 on a Firefox Browser:

Application error: a client-side exception has occurred (see the browser console for more information).

Despite trying all available solutions, importing bookmarks from Chrome does not work in this firefox latest version 150.0.1. When importing Bookmarks from Chrome, the Saved Passwords file is fully imported and shows 163 Nos. imported. But on opening Firefox, nothing is there. No folder contains imported bookmaks. Tried importing several times, but to no avail. Uninstalled, restarted PC and reinstalled firefox. But importing Bookmarks and Passwords from Chrome sucks. I am fully aware of the procedure. So no more detailing needed. Using firefox since the last 16 years. But the software makers are simply spoiling a good browser by deliberately creating issues. Tried importing from saved html file of bookmakrs, but that also is not helpful. Why Firefox is deliberately causing such errors with updated versions? Please release next version after thoroughly checkining this importing feature and ensure that it works correctly. I tried uninstalling, restarting the PC and reinstalling with with full offline installer as well as online installer. Nothing helped. Chrome works smoothly. Earlier firefox did not have any such issues. With each update, problems after prblems started creeping in with someone deliberately tweeking the software and spoiling a good browser. Please look into it seriously and provide a solution.

Webgl has completly broken after last update for me. Forcing webgl in about config doesnt work and it doesnt work in troubleshoot mode either. Anything else i can try apart from reinstall from scratch as im worried about losing my history,saved account info and such. Or do i just need to do a full refresh and install? Thank you!

I HAVE FINISHED SET-UP BUT I AM STILL BEING PROMPTED TO FINISH, WHY FIREFOX IS MY DEFUALT BROWSER IHAVE IMPORTEDTED SETTINGS AND MY SYNC IS COMPLETE UNDER MY PROFILE

Hyperlinks keep opening in new windows, not in the same/existing window where they were selected. Issue is not unique to Google Search results and occurring across multiple websites. At wits end trying to figure this one out. I have deselected the "Open links in tabs instead of new windows", turned off all extensions, and uninstalled & reinstalled Firefox. Issue is still occurring. Attached is image of my tab selections showing all turned off.

it is obvious your system has changed: I have windows 11....the help I see is for windows 10

where are the current updates?
