It is soooooo Slow. I don't know why the hell I still have it installed on my laptop. It would be a year before a webpage loads up. Thank Goodness for Google Chrome Plus. I am faithful to Google I will never cheat on it with Safari.:)
Is halfway decent now, but only because they stole every single good design feature that Mozilla has.
But ever since I started using Firefox I will not go back. It is so much better. The addons are fantastic.
And open source FTW, baby!
