Tab Scope breaks OS X fullscreen mode

[hsiktas]

Hi, as soon as I use Tab Scope on OS X 10.8/10.9 the Firefox full-screen mode breaks. Whenever Tab Scope is trying to show a thumbnail in the full-screen mode OS X switches back to the previous desktop space. Outside the full-screen mode everything works as expected. To work with Firefox on OS X and the fullscreen mode I have to disable Tab Scope or I have to use the alternative full-screen mode offered by this add-on: https://addons.mozilla.org/en-US/firefox/addon/old-lion-fullscreen/

Are there any news on this? My pull request is still working (and necessary) on the current Tab Scope version and Firefox 40a2.
