How do I stop firefox from ever going to full screen?

Quite often I accidentally double click on a video or a picture and Firefox decides it means I want to go to full screen. In my case it never does. I have never wanted to use full screen for anything in a browser and yet several times a month it decides by itself to go full screen. There is after all a reason I am using a computer and not a tablet(multiple windows).

So how do I stop Firefox from ever going to full screen mode regardless of what happens in Windows?

I have tried doing searches both on search engines, extensions and Firefox help site but all results seem to just point at the opposite solutions of always being full screen.

Chosen solution

I can't think of an example where double-clicking an image or video causes it to go full-screen. On the other hand, I am very familiar with full-screen buttons on video player toolbars. If you don't want that kind of full-screen -- the kind that webpage scripts can invoke -- try this:

(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.

(2) In the search box in the page, type or paste full and pause while the list is filtered

(3) Double-click the full-screen-api.enabled preference to switch the value from true to false

Did that do what you need?

Thank you. Seems to help. So it was just a large number of misbehaving web sites then.
