It's probably the JavaScript compiler -- it plays fast and loose with stack frames to get everything to fit in the limited OS X PPC stack range. If the browser starts okay in safe mode, that's the problem (hold down Option as you start it). And, like theos911 said, use the G3 version.
I get periodic questions about an Intel TenFourFox, but I don't use Intel 10.4, and I have a standing rule I don't support software I don't use (which is sort of a question about TTYtter since I don't use Twitter much if ever anymore -- moved to App.net). However, I would be happy to point people towards such a build and maybe even host it.
It would not be difficult to do: you'd have to undo the current JS compiler and point it to the built-in x86 one instead, change the AltiVec code to point to the built-in SSE2 equivalents, and make sure we haven't made any big-endian assumptions (usually we're dealing with code that makes little-endian assumptions). This is non-trivial, but the x86 code obviously is already in the code base; you just have to get everything pointing back to it, since I didn't really design the source for cross-compilation. Then you can use the 10.4-widget, graphics and font support, which should work with no changes.
Interested? Grab it, give it a spin, let me know how it goes. But I have too much on my plate to support it myself, especially since I have no way of really testing it.
