Corrupt firefox file which one to delete?

[dogbone]

My page up and page down buttons are not working. They are working in my troubleshooting account so I know it's in my home folder.

I trashed the mozilla.firefox.plist file but that didn't help.

I can't work out which file is causing the problem. Does anyone have an idea?

Thanks.

For future reference.

It was a prefs.js file located at

~/Library/ApplicationSupport/Firefox/Profile/ckbfcc0h.default/prefs.js

took me about 2 hours of testing all the files in ckbfcc0h.default to find it.
