Chatzilla works - you just need to get the latest version.
I'm far from blown away by this new version. As the developers have said, this version is only really about adding in behind-the-scenes stuff in preparation for version 2. At least it hasn't got worse (well actually table rendering has got even slower but most folks won't notice that).
Supposedly it's more secure - anyone know any more about that?
taz, Chatzilla was just late updating. It works now.
As for Firefox, I think that 1.1 would have been a better signal about the level of visible improvement, even though there was major under-the-hood work (here's their "why"). I do find the memory management significantly better, though, which really helps (I burned out a stick recently and so I'm short).
Here are the 1.5 Release Notes. One significant "invisible" feature is an improved extension API -- one reason so many of them broke.
Also, I meant to say this earlier, but I passed out... OPERA REPRESENT! I want the browser wars to become sort of like a gang war at some point with drive-by shootings and territory and bandannas and/or bananas.
People often miss the point about why Firefox has been so important. The browser "market" had completely died and there was virtually no movement or innovation. Once Firefox turned up and getting a share of the market it started to scare the shit out of everyone else.
Now look where we are: Microsoft updated IE even though they'd previously stated there would be no updates until Vista and Opera is now available for free without obnoxious ads.
Even if you don't use FF you have to be glad about it's effects.
