3 or 4 days ago, a popup came on my Facebook page saying that Firefox needed to be updated or fixed, sorry I don't remember what it said. I clicked on it and kept on the page with no problems. Got off the a page about an hour or so later. Came back later and tried to play a couple of games and they wouldn't load or took forever to load also a yellow lock showed up which was always green before. Went to the Monzilla site and tried to figure out what to do. Reinstalled Firefox as suggested and seemed to work after that. Came back later and tried to get on again and had the same problem. Again reinstalled Firefox, but this time it didn't repair it. Since that time, it hasn't worked to completely open at all. I have tried several times to reinstall since and still won't work or install partly. Have also run Norton complete system scan several times including Norton's eraser still didn't do anything. Been using Firefox for years and never have any problems before, I'm at a total loss.

As you can most likely see, I'm not a computer wiz, but, do use it several times a day.

For the last five months, an epidemic of Fake Update Notices have been popping up all over the place. https://support.mozilla.org/en-US/kb/i-found-fake-firefox-update


You may have ad / mal-ware. Further information can be found in the Troubleshoot Firefox issues caused by malware article.

Run most or all of the listed malware scanners. Each works differently. If one program misses something, another may pick it up.
