In case you really want to get rid of FB theater mode for photos, you can do so by following the simple trick given below. But note that, it is not a permanent solution, and just a work-around.
How to disable Facebook Photo Theater mode?
Solution 1: When you click on a photo/album, it will open the photo in the theater mode, now in the address bar, look for “&theater” and delete it. Then, it will open the photo in the old format and you can start browsing the album as you used to do before. Solution 2: A faster alternative for Option 1, is to refresh the browser. When reloaded, the photo will open in the old format and you can continue browsing as before. As I mentioned before, neither of these solutions are permanent. When you go back to your feed and open a different photo/album, it will again open in the theater mode, and you would have to repeat either of the solutions. Hope Facebook gives a setting to toggle the theater mode or some developer comes out with a browser extension to handle this. Update: It didn’t take long for someone to come out with a userscript! Install for Firefox here and Chrome here to permanently disable Facebook photo theater view! Thanks Binoy!
