User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:35.0) Gecko/20100101 Firefox/35.0 Build ID: 20140917030202 Steps to reproduce: Press `/` on any site in an e10s window. Actual results: Brings up the quick find bar. Expected results: Not sure whether the intended goal is to bring it up but allow sites to preventDefault on it, or if it's just accidental, but Gmail for example uses the same binding to focus on the search field. Nightly (35.0a1 (2014-09-17)) non-e10s window focuses on Gmail search field as expected. e10s does not.

Am able to reproduce. This binding should at very least allow sites to override it. Even better, it should be bound to a modifier key (what was wrong with CMD+F?)
