Yes. For start I worry that if I will use YouTube while logged then it will increase risk of my mail account being randomly banned by Google. I already got "your account is temporarily disabled" once after I used "import mail filters" feature. Also, I do not want to risk accidentally sharing exact videos I watch, while logged in. Also, I anyway need to download videos as browser player lags while VLC does not.
