I look forward to hearing how later kernels could be coerced to run. Hopefully the source can be discovered and the PPC-specific sections forward ported.</p>
<p>I try not to break Snow Leopard intentionally in TenFourFox because I know of people who run it under Rosetta and this use case amuses me, so I try to keep it working. However, it is certainly possible that some things don't work or aren't tested and officially it will remain unsupported, even if SL can be made to run on PPC, simply because there are probably other bugs yet to be discovered. That said, I <em>can</em> promise I won't do anything <em>on purpose</em> to mess it up.</p>
<p>The JPEG issue is probably due to TenFourFox using the operating system's built-in AltiVec JPEG decoder and Preview is probably relying on it too. ArcticFox uses the Mozilla in-tree unaccelerated libjpeg, which is my guess why it works. An easy test to prove this is running a G3 or debug build of TenFourFox, which use libjpeg as well. If these display images correctly, then this is the explanation. The solution here may be a custom build. If you want to build a TenFourFox that is properly optimized for a processor but doesn't use the OS image decoder, then just remove <code>--with-system-jpeg</code> from the <code>.mozconfig</code> you're using. Please note I would not officially make or support such builds.</p>
<p>You could run this on a Talos II with KVM and it's probably how I'd mess with it myself rather than on an actual machine, but the main problem is that QEMU doesn't do 64-bit KVM for G5 properly yet (it panics the kernel). It will work as a G4 but run abnormally slow.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/482876032020-04-30T13:42:13Z2020-04-30T14:12:29ZTenFourFox on PPC 10.6 (!) and also 10.6 PPC on Talos (!!)<div><p>Hello there, just updated TenFourFox to Release 21 on my Power Mac PC G5 with OS 10.5.8<br>
I'm finding it's running quite slow compared to the browser from you previously<br>
and slow to load photos on websites.<br>
Is there anything I can to do help this out on my aging Power Mac?<br>
Much Appreciated.</p></div>Ken Gold
