I've been using Firefox for years on my aging Win XP system. I used it this morning. Then I did periodic maintenance which included a Disk Cleanup, a Defrag, and a Malwarebytes scan. After rebooting, Firefox refuses to load. I get a message entitled "Mozilla Crash Reporter" with the message "Firefox had a problem and crashed. We’ll try to restore your tabs and windows when it restarts." There are two options: Restart Firefox and Quit Firefox. I've tried both several times without success.
If I click on the Details button, I get this:
AbortMessage: ###!!! ABORT: new XPCJSContext failed to initialize.: file c:/builds/moz2_slave/m-esr52-w32-000000000000000000/build/src/js/xpconnect/src/XPCJSContext.cpp, line 3474

This report also contains technical information about the state of the application when it crashed.
I have rebooted several times with no success.
I do have internet access as I am able to send and receive email and I am sending this from Internet Explorer.
I tried downloading and reinstalling Firefox, but the result is the same.
Any suggestions? It was working this morning.
