User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:27.0) Gecko/20100101 Firefox/27.0 (Beta/Release)
Build ID: 20140212131424

Steps to reproduce:

On default profile, bookmarked some webpages, picked a theme, visited new website, downloaded Youtube HD addon, to test Sync for another profile two.  Pressed F10->Sync Now, waited 5 minutes, closed Nightly and started profile two from Profile Manager.

After F10->Sync Now on profile two, it got most of the bookmarks minus www.facebook.com, theme didn't sync, addons didn't sync, but new website visited is in history.  Closed Nightly and opened default profile again from Profile Manager.

Go back to default profile, opening page is streaming website www.twitch.tv which is where I noticed the black boxes/glitching


Actual results:

On that page, the streamers screen was now flashing/glitching in and out quickly, black boxes kept flashing in and out at certain spots (also chat area was bugging out).  Switching to other tabs, I could still notice the black boxes/glitching on certain ones.


Expected results:

No glitching after Syncing upon returning to original default profile
