unable to log in to Facebook (only with Firefox)

Hi, Firefox is the only browser I use, as a general rule. I have a Lenovo laptop, running Windows 10, and I use Avast Free antivirus. Last night the Avast updated itself; I may have also had a Firefox update but I don't think so; I don't remember being asked to restart Firefox. Anyway, since that time I have been unable to log in to Facebook: I get the log-in screen, input email and password, and it goes to a blank white screen with the url at the top, as if it were loading, but it doesn't load. I am able to access Facebook normally using Edge (and also on my Samsung tablet), so the problem is not with Facebook. I have tried running Firefox in Safe mode (?), restarting Firefox, restarting my computer, etc., etc. Everything says it's up to date, too. Please tell me what to do; I would much rather use Firefox than Edge.

Boot the computer in Windows Safe mode with network support to see if that has effect in case security software is causing problems.

You can remove all data stored in Firefox for a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History -> Show All History" or "View -> Sidebar -> History").

Using "Forget About This Site" will remove all data stored in Firefox for this domain like history and cookies and passwords and exceptions and cache, so be cautious. If you have a password or other data for that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of involved files.

If you revisit a 'forgotten' website then data for that website will be saved once again.

You can try to login to Facebook in a New Private Window.

You can check for issues with location storage (indexedDB).

This could be a problem with local storage and possibly running this command in the Web Console to clear storage as posted in bug 1569296 might fix it.

  • localStorage.clear()
