Firefox build optimized for my PowerBook 12" 867 MHz

I haven't used Firefox for so long. As far I remember, last time I used it was when I used a hackintosh on September 2008 (it's a ordinary PC, installed with a hacked version of Mac OS X 10.5.5). I love Firefox because of it's extensible. You could add various features & capabilities to it which is basically it can't. By installing/adding add-ons to it, Firefox could have more features and capabilities. For instance, what if you'd like to download a video you like from YouTube? You could utilize an add-on called Video DownloadHelper. What if you'd like to read news from various websites/sources that support RSS/Atom? You could utilize Sage or Wizz RSS News Reader to make Firefox behave more beautifully handling those news feeds, even though Firefox 3 has better capability handling RSS. What if you want to download files from links that appear in a web page and you want a resume download capability? Let FlashGot or DownThemAll come to the rescue. You could do many things inside Firefox without have to open & run separate application. That's great right?

Until several days since I have to use again Firefox on my PowerBook 12" 867 GHz, with 1.12 GB RAM. I have to admit that those luxuries capabilities of Firefox with its add-ons is a waste. I can't stand with its slowness in responding my basic browsing activity. It's far too slow compare to Safari 3 which I usually use (fyi, there is Safari 4 beta available, both for Mac & Windows). Believe me, I've tried Camino, but it's suffering the same problem with Firefox 3. Why I don't use Safari instead? Well, because my wife is opening her Facebook, and at the same time I want to open my Facebook too. Don't ask me to buy another Mac, this solution is definitely cheaper.

Why Firefox 3 is slower compare to Safari 3? Well it's because Mozilla's team build a generalized version of Firefox 3. Apparently, different CPU requires different way of building such an application to. Fyi, there's different CPUs Apple had used before they use Intel's CPU: G3, G4 7400, G4 7450, and G5. They all RISC's CPU types.

Is there an optimized Firefox 3 for my PowerBook? After googling a while, I finally found a great link: Firefox Mac Community Builds. This page lists all Firefox's builds for G3 to Intel Mac based systems. For you who would like to try an optimized version for Intel machine beside Firefox Mac Community Builds' offering, you could try Neil Lee's build.
Mind one thing, optimized Firefox doesn't named Firefox. Instead, they are named Minefield, considering Firefox's trademark.

And for you who'd like to try an optimized version for Camino, Thunderbird, and SeaMonkey, you could find it here.

I'm still waiting for Google Chrome release for Mac OS X. It's still the fastest browser base on recent benchmark compare to Firefox, Safari, Opera, and Internet Explorer.
