I have this problem with Firefox... it crashes when I wanna send Email form my Yahoo Email page. While Torbutton is enabled. I had that problem last week too but I fixed it by deleting Yahoo State Plugin. Now the same problem shows up again. Mozilla crash a little bit after I hit send button. This is link to my last Firefox crash: https://crash-stats.mozilla.com/report/index/4c77fa12-5b3d-4742-824d-cefa82110701 By the way I always get empty signature crashes. None of them had signature. Hope you will help me solve my problem. And thank you in advance.
