I'm running firefox beta 2 on my g4 iBook & intel iMac. If you are complaining because you have it set to auto-open then please use some common sense. When the computer first boots into the OS it has other tasks to perform before it can load firefox.
with that said the only program I have set to auto open is mail & ichat. but I would never complain that they took longer to load on startup.
as per general use on my iBook firefox bounces 2 / 3 times then is good to go. on the iMac its pretty much instant. if its taking 6 bounces to load normally then something is deff messed up with your macbook being you have 2 gigs of ram. it should bounce once / twice at the most and get on with it.
to the user who posted the optimized build of firefox for intels. how does it compare to the release firefox releases that are UB?
I have tried camino - and quit for 2 reasons. no adblock plugin & the bookmark toolbar is awful looking.
I have tried Omniweb - and quit for a few reasons. no adblock, poor pop up protection, & the bookmark toolbar is awful looking.
Why do they insist on having an ugly default favicon is beyond me. With Firefox using the silver theme it looks really nice & clean. favicons are just ghetto in my opinion.
I have used safari with pithhelmet & saft and its not bad. the toolbar bookmarks look great, however I have never found it to be quicker than firefox.
best of luck.
