Shows a page action for imdb/rotten tomatoes film pages to go to the letterboxd equivalant
Adds an icon in the address bar that comes up on Imdb and Rotten Tomatoes film pages. By pressing this icon a new tab will open that goes to the letterboxd film page.
*Note: This extension is not made by the letterboxd team but someone who is a big fan of their site!
Update 4/17/15 - Fixed the bug with Rotten Tomatoes so its now working again from there!
