TenFourFox Unsupported i386 Build on 10.4.3

Sorry and I don't know where to report the question... is there any way to bypass some kind of restriction that appears to be in place that limits the unofficial / unsupported build of TenFourFox for INTEL from running on the Intel build of 10.4.3?
Sadly, this is that highest possible os that my DTK can run, as apple switched to EFI for all later builds and depreciated the developer only prototype hardware, but I can run many other intel MacOS software builds fine...

Much appreciated, as I'm a huge fan of trying to keep this rare hardware running and using it to perform somewhat mundane daily tasks, so TenFourFox Intel running on here (even if unsupported) would be better than the massively outdated Safari or Firefox builds that barely operate in the modern world.

    Please see this thread (last post) for a way to buypass the restriction. Doesn't mean the browser will actually run but you can give it a shot:

    Thanks- Tried it, it barely bounces in dock and closes- probably something that’s not compatible between 10.4.3 and 10.4.9.
    Ah well, was worth a shot anyway!

    Yeah, that means there are probably missing symbols. You can look at Console.app to see if it gives you any clues.
