Facebook recently rolled out a new Photo viewer which provided users with a theatre like view for viewing photo albums. Though the new Theatre view for Facebook works well, it is definitely not liked by everyone.
So what if you don’t want to view photos using the new Facebook Theatre view? Well, you cannot disable it directly using Facebook but you could use a Greasemonkey userscript for Firefox and Google Chrome to disable the theatre view in Facebook.
The "Facebook Photo Theater Killer" userscript kills the annoying new photo theater on Facebook and allows you to browse the photos the old way. This script works on Google Chrome and Firefox only for now.
So go ahead and install the script to get rid of the new annoyance created by Facebook. Thanks Binoy.
Update: If you use Google Chrome, you can also use these extensions to disable the new Facebook photo viewer.
