A port of Firefox 2 for Castle Technology's IYONIX PC has been released by Peter Naulls. This release comes after users contributed the 1000 GBP that Peter had asked for to fund the development.
Peter would like to thank all those who contributed, but he is still after another 4000 GBP to release a further update with integration to RISC OS, and fixing some other issues. This release is targeted for Christmas day if the contributions meet the target.
A port for Advantage Six's A9home computer has not been ruled out subject to financial interest, and Peter is asking people interested in a port for any RISC OS platform to email him.
Update: Rob Kendrick has released a patch that allows the IYONIX Firefox port to run on the A9home by providing emulation for the XScale-specific instructions to a fudged copy of the Firefox executable.
