I downloaded firefox and it worked for about a month. Now when I try to launch it, the screen flashes momentarily as though it were about to pop up, but then it does not actually open a browser window. I have uninstalled and reinstalled firefox more than once, I've tried a simple restart of the computer, and tried multiple different update methods (updated windows). Any suggestions?

Hi Robey,

looks like you're still using version 138. Can you try updating to the latest version (140.0.2) and let us know if that fix your problem?

So one user on the computer doesn't show version 138 and can access Firefox no problem. This account shows both version 138 and 140 but I can uninstall version 138. I am having the same issue with Chrome of it not launching, so it may be a Windows issue

That's MS Family interference.

- go to https://familysafety.microsoft.com or open the Family Safety mobile app

- select the child 

 - allow other browsers:

   - disable 'Filter inappropriate websites' under the Edge tab, or

   - go to Windows tab > Apps & Games > unblock FF

If you can't do anything there, try disabling the [Parental Controls service](https://impulsec.com/parental-control-software/microsoft-family-safety-turn-off/#Disabling-Microsoft-Family-Safety).
