These "crashes" aren't in the Report, so I'm not sure what to do. I've pressed Quit, I've cleared the Cache (twice), and I've deleted and reinstalled the app. Firefox was working just fine until recently. These crashes only to seemingly happen on YouTube and Tumblr. It closes worse when I have the YouYube in Background Add-on on, but it isn't just because of that. If anyone knows how to fix this, feel free to answer.
