I am getting a lot of pop-up messages for existing of many viruses on my computer. Please help me protect and then permanently remove these viruses from my computer.

I'm not sure why, but starting a couple of days ago Firefox will not load a couple (there may be others) of my regularly used sites - the page just 'hangs' or only partially loads:

facebook.com theguardian.com

These are on my Windows 11 PC which I use 95% of the time. They load fine on my Windows 10 laptop which has the identical Firefox settings (they are Synced) with the same Extensions.

I have uninstalled and reinstalled Firefox on my PC to see if this helps, but the issue remains.

The websites load fine using Chrome on my PC.

Can anyone offer any thoughts as to why this is happeneing and offer any solutions?

My desktop (Windows 10) Firefox just updated to 145.0.1 and the right-click menu is defective. It has a bunch of blank lines, the only options listed are search DuckDuckGo, translate, and use AI. This ruins my browsing experience, since I can no longer open links in new tabs which is my favorite way of looking at newspaper home pages.

I have been using Firefox for many years and never had issues. Two days ago, I turned on my HP with Windows 10 and I got a pop up message something about Error Platform 126.0 XUL Runner is not compatible. I could not access Firefox, Google, or the internet. I uninstalled Firefox and reinstalled, but after that, everything runs very slow. Each time I go into a website, it can take up to over a minute to pull up! I cannot even delete email from my Gmail! It's piling up. Downloading can take over an hour! I checked all the trouble shooting forums in Mozilla and tried just about everything. I went back into "About:profile"s and created a new profile. It it did not make any difference. I also did a Firefox refresh. Did not help any. I went back into the profile I had before the XUL error because my bookmarks were there. Still slow. I cleaned out the cache, in both Firefox and my Windows 10. made no difference. I only have three extensions in Firefox. I don't know what else I can do to fix this. Also, my drivers and other software are automatically updated by Windows. My HP is only 2 years old as well. Everything was fine in Firefox until that XUL error message popped up and I had to uninstall and reinstall Firefox. That is when everything became agonizingly slow!

Update: My computer is barely usable anymore because of the Firefox issue. Having to wait for a minute or more for everything I do on the internet? I know it cannot be my computer itself because it is not even two years old yet. I may have to dump Firefox if I cannot get this fixed. I have Norton 360 and it is not malware or a virus. Firefox messed something up.

I have been trying for WEEKS NOW to sign into my bank! The bank can use a TEMPORARY password to access my account but once that's over, when I try to log into my bank I STILL CANNOT LOG IN!!!!!!!!!! WTF has happend to Firefox after that last "update" what ever it was they changed, made it IMPOSSIBLE for me to log into my BANK. The problem is NOT the bank it's FIREFOX & FIREFOX NEEDS TO FIX THIS CONNECTIVITY PROBLEM SOON IF NOT SOONER!

Hello, I’m using Mozilla Firefox on Windows 10.

The issue happens mainly on YouTube: – Videos stutter every few seconds – Audio sometimes goes out of sync – This happens on 1080p and 720p – My internet speed is stable (~XX Mbps)

So I have had a favorite URL in Firefox for a decade or more https://www.outlook.com/owa to access outlook.com via web browser. Microsoft in Firefox only since the last upgrade does some weird looking and throws an error saying to try again later. If I delete my cookies for live.com and refresh the link it brings me to the sign in page where I can put in the email/password and it opens fine. If I close the window same thing happens and have to clear cookies, etc. Doesn't have the issue on Chrome or Edge, but thought I would make someone aware something odd is happening there. For now I just am using an alternate link https://outlook.live.com/mail/0/ and it comes up fine but it is not re authenticating again at that point.

Is there something I can do to avoid the error?
