Browser issues

This is the third try of finding a bug-free firefox release for Mac. I started with the official versions, of course. A few weeks ago, I found a link at del.icio.us for optimized firefox releases for different PowerPC versions.
I checked the so-called stable release for new G4 processors and it really was faster while browsing the world wide web. But only a few days later I recognized, that some sites made him crash heavily. Switching back to the official release did not help. It was unable to handle that websites, too.
I then stumbled over a german version. It worked. Still does. But I hate those german menus. They sound awful and most are so long that you have larger windows.
Tonight I tried the unstable firefox build of March, 22nd.
That one worked fine for about two hours and then crashed at another site.
And no, I am not in the mood for checking if it works with the official, german or any other damn nightly-build release.
