Firefox not working properly

I'm on an older computer, Windows 7. Hadn't used it for a while and now when I open Firefox, instead of seeing a screen full of info, I'm only able to see the top 1/4 of the screen. For example, my typing here -- I can only see the top line to the word "seeing" and then I can see my second "I'm" -- everything else disappears off the edge of the screen. Not able to tab or side arrow over. Other apps work fine and now I'm using Chrome because it doesn't do this. Firefox on my other Windows 7 computer doesn't do this. I've tried all the display settings, but nothing I've done fixes it. I'd prefer to use Firefox but right now don't have a choice.

Can you attach a screenshot ?


Try to rename/remove xulstore.json in the Firefox profile folder with Firefox closed.

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.
