On Facebook, I've found that if you remove the
&theatre from the URL when viewing a picture, it reverts back to the original way of viewing pictures.
Is there any way I can make the removal permanent?
Kills the annoying (IMHO) new photo theater on facebook. Instead loads the old photo viewer, as long as facebook keeps it running.
Hope this helps.
Social Fixer, an extension / user script for Firefox, Opera, Chrome and Safari, can be configured to disable the 'Photo Theater' in Facebook, among other Facebook site fixes and enhancements.
