While it may not come as much of a surprise, it's still going to aggravate owners of aging PPC Macs that the upcoming Firefox 4 browser is probably going to drop support for the older architecture. Mozilla program manager Mike Beltzner noted that the next version of the open-source browser, currently in beta, is not working on PowerPC machines now and the update will not be automatically offered to them.
It's not clear if the Camino browser, which does work on both Mac processor platforms and is based on the Mozilla Gecko rendering engine, will be able to update to the Gecko 2.0 platform that powers Firefox 4. In the same message thread, Beltzner allowed that developers could certainly work on a PPC version that left out the two problematic components, but that it most likely would not be allowed to carry the Firefox brand (which has happened before with custom optimized builds for specific architectures). He also pointed out that there aren't development resources within Mozilla to extend support for OOPP and the JIT compiler to PPC, and that outside help has not been forthcoming.
