Many users, myself included, visit YouTube on an almost daily basis. Ever since Firefox version 2.0 implemented the session restore function, when you are watching a video on YouTube (perhaps on other video sites as well, I haven't really tested that), you may notice a tiny freeze-up of the video every 10 seconds or so. This happens because the session restore is by default set to save all open tabs every 10 seconds. This is especially noticeable if you happen to have a lot of tabs open at once.
The quick fix for this problem, at least for my own sake, is to increase the time between each of the saves performed by session restore. By opening about:config in your Firefox address bar, then typing browser.sessionstore.interval in the filter box, you'll see a value of 10000, which is in milliseconds. (Meaning your session is saved every 10 seconds.) I changed this...
