Firefox is slow and stutters

I've been seeing this problem since last year and I'm about ready to switch to another browser because of it. Firefox stutters when it opens some websites, and I think the problem has to do with self-starting videos and video ads that appear on those sites. For example, the NY Times (nytimes.com) now routinely places video ads near the top of its home page, which I think causes that webpage to jump up and down as the browser loads the ad. This even happens when I open a new tab from a link on the nytimes.com homepage, and then return to the homepage. The page appears to refreshe automatically, as does the video ad, even though I only clicked on the tab to return to the homepage, not actually do anything on it.

A bit of this happens with Safari when I first open nytimes.com, but it is not nearly as bad. I'd like to stick with Firefox, but all this jumping around is ruining my experience. Is there a fix?

Thanks Fred. I have AdBlock on Firefox but for some reason I don't remember, I had disabled it on NYTimes.com. Enabled it and solved the issue -- for now! Thanks again!
