Anyone else experiencing problems with Firefox all of a sudden? It's been fine for months, then just this past week, it's started acting up. It takes forever to load some pages, or just doesn't load them at all. Sometimes I have to click a link several times to get it to even start trying to load it. It doesn't load pics on some sites, and myspace loads but without half the graphics and with none of the pics. Safari loads everything quickly and effectively. What's going on?
