Youtube vids keep buffering, but only when I sign in to my channel. Sign out...they play fine.

[Survivor Kitty]

YT vids keep buffering when I'm signed into my channel. BUT, they all play fine when I'm not signed in. I removed and reinstalled both Firefox and Adobe Flash. Also have VLC. Tried disabling one at a time...no help. Used to run fine w/both players enabled. Downloaded 2 latest FF updates. My bad??? Help please.
