Puntuado con 4 de 5 estrellas

I need to downgrade my rating from five to four stars--it just hangs for 3-5 seconds too often (1/4-1/3 of the time?). Get rid of that bug and you'll be golden.

There was a significant rewrite done in version 2.01. The 2.x extensions should be faster, and if you want it yet more speedy, try turning off use of favicons in the options panel in 2.x versions or try reducing the number of days of history that firefox is allowed to keep. It's usually set to 90.
