Turned on laptop (rebooted) after being away from it for a few hours. Went to open my home page. Error message popped up saying Firefox is already running and must be closed. I closed it and another error message popped up saying Firefox can't open - incomplete or missing files.

I went into Processes to close Firefox. Selected 'end process' but nothing happened.

Tried to use Internet Explorer but it just gets hung up. Cannot access anything.

And, because I can't open Firefox, I can't go a refresh.

Everything was working just fine a few hours ago.

Any thoughts?

Firefox hangs or is not responding - How to fix

Open the Task Manager and quit the process. If this continues to happen I would recommend starting the PC in Safe Mode with networking.

What is the computer system and Firefox on the bad computer?

Separate Issue; Your System Details on this computer shows;

Multiple versions of your Adobe programs.

Having more than one version of a program may cause issues.

Go to adobe.com and download the full installers after removing all of the old programs.

Start Firefox in Safe Mode {web Link} by holding down the <Shift>
(Mac Options) key, and then starting Firefox. Is the problem still there?

This is not a cure but will make it easier if Firefox locks up in Windows. https://support.mozilla.org/questions/997866 {web link}
