Problems with Firefox or Fedora?

Is it me or is Fedora’s Firefox slow? This is really noticable on my machine when viewing Myspace pages, especially ones with playlists. With pages like these, it scrolls reaaaally reeeeeaaaaaly slooooowly. Also, it seems to load pages much slower than in Windows (something in Windows that is actually better than its Linux counterpart?!?!?)

Another problem that I’ve noticed is that when running Blender, it shows the title bar, but if I try to drop down a menu like File, or Render, It shows a white square, about the same size as the menu should be covering the GNOME panel, and it looks like the Blender panel that the File, Render, etc, menus are on covers the GNOME Panel, but if I move my cursor over icons or click on GNOME menus, it replaces that section of the Blender panel with the menu or whatever I clicked on, kind of like a hallucination, if that makes any sense.
