Bye Firefox 2

I am a great fan of open source software and so far I’ve used Mozilla/Firefox browsers since their very early releases. However the newest Firefox 2 basically rendered my Powerbook useless. After loading a site it would spin the colored wheel icon for seconds until it allowed to scroll the page. Switching between tabs would take several seconds and would freeze the UI until done, scrolling up/down would take several seconds… (this happened basically for every single action)
So I’ve installed Opera for Mac now on my box and it feels like I’ve upgraded my internet connection, browsing hasn’ been such a pleasure since a long time. I do prefer open source, but this was not tolerable for me. So for now it is: good by Firefox2, Opera here I come (at least on the Mac).
