The screen is only displaying 3/4 of its size. I've tried troubleshooting but it still come out looking like this.

Chosen solution

It could be the work of one of your add-ons. Type about:addons<enter> in the address bar to open your Add-ons Manager. Hot key; <Control>(Mac=<Command>)<Shift> A)

In the Add-ons Manager, on the left, select Extensions. Disable a few add-ons, then Restart Firefox.

Some added toolbar and anti-virus add-ons are known to cause Firefox issues. Disable All of them.

If the problem continues, disable some more (restarting FF). Continue until the problem is gone. After, you know what group is causing the issue. Re-enable the last group ONE AT A TIME (restarting FF) until the problem returns.

Once you think you found the problem, disable that and re-enable all the others, then restart again. Let us know who the suspect is, detective.

Check your zoom controls. Holding down the <Control>(Mac=Options) key, press; + (plus) enlarge - (minus) reduce 0 (zero) restore

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

You can use this button to go to the current Firefox profile folder:

Thanx guys for your tips, but unfortunately they didn't work. I removed the xulstore file and tried the zoom controls but the screen still looks the same. I'll upload a screenshot, maybe that can be of any help.

I see nothing wrong. Are you talking about the dark area on the bottom? That is an overlay.

Exactly, but how do I get rid of this overlay, any ideas?

Problem solved! Thanks a lot. I disabled all my add-ons and restarted Firefox and the overlay was gone. Then I activated my add-ons one by one until the problem started again. I seemed to be AdBlocker that was causing it. So, there you have your suspect... arrest him officer... put him behind bars :).

That was very good work. Well done.

AdBlocker may be set up to not cause that problem again. Check with its support.
