It has been two days that using Firefox 4, the Youtube’s Progress bar suddenly has disappeared (it is usually pink). As in, it isn’t visible to the eye. However, it works. I can click where the pause button would be and it pauses or unpauses, mute button works fine.
The solution wasn’t o reinstall Flashplayer (I have the latest version to date: 10.3.181.14) and it wasn’t a new Youtube’s interface redesign, the real solution was to go to Options, Cookies, search for “youtube” and delete all the cookies with this keyword. It wasn’t necessary to reload the browser, everything returned to normal immediately.
