My baby got a hold of the laptop and hit the keyboard a few times. Now I have lines going vertical, horizontal, and diagonal as well as around the address bar and some input boxes. I have refreshed firefox, uninstalled and reinstalled as well as looked under config browser.display.focus_ring_style to zero. I believe it is something in firefox not the computer since it only occurs there. the lines on the screen move with it when I scroll if that helps. Any suggestions would be appreciated.

Can you attach a screenshot?


You can delete possible user.js and numbered prefs-##.js files and rename/remove the prefs.js file to reset all prefs to the default value including prefs set via user.js and prefs that are no longer supported in current Firefox releases.

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
