Fixed by a quick browser restart. May have something to do with Tab Mix Plus. Reproducible: Couldn't Reproduce Steps to Reproduce: 1. 2. 3.
After a long period of trying to reproduce, it happened by pure accident. It more than likely has something to do with Tab Mix Plus. I believe that it happens from leaving the "Restore crashed session" window open for an extended period of time, but I'm not 100%
Resolving as WORKSFORME since even the reporter isn't able to reproduce. Kyle: Issues related to Tab Mix Plus will first have to be reported to the extension's authors so that they can check whether this is their bug or ours.
