Every time I start up Firefox, I get the following: JavaScript Application "mfernandez1957" Invalid username/password combination. If you continue to get this error, try entering your email address as your username.

What do I do?

Another issue is hang ups, I mean every few seconds it hangs up and I get (Not Responding), which is frustrating when you're entering data or whatever and in the middle it freezes so then you have to go back and retype stuff that never got entered. It even hangs right out the gate, I get (Not Responding), I mean, before Firefox is even fully loaded, it hangs, it even hangs (though considerably less frequently) with all my plug ins currently disabled. So that's another issue.

If y'all can help, I would be grateful.

Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

  • Do NOT click the Reset button on the Safe Mode start window or otherwise make changes.

Try to delete the sessionstore.js file and possible sessionstore-##.js files with a number and sessionstore.bak in the Firefox profile folder.

Deleting sessionstore.js will cause App Tabs and Tab Groups and open and closed (undo) tabs to get lost and you will have to recreate them (make a note or bookmark them).
