@Leo: The resources I mean are the thousands of pounds wich will likely be spent by RISC OS users on Oregano3 instead of on plugins that would work with all RISC OS browsers and might be released as open source software.
IIRC the RISC OS browser plugin interface was very similar to the Netscape plugin interface, wich Firefox supports already and wich is also supported by almost all browser plugins on other platforms (many of wich are open source). So I guess it should not be too complicated to make Firefox work with the RISC OS browser plugin interface as well?
My definition of a browser wich works with 'typical sites' is one that works with 99% or more of the websites out there. Firefox on Windows seems to do that, so I don't see why Firefox on RISC OS should not get there as well.
Also Firefox is growing its market share so quickly, that many website developers are starting to optimise their sites for it. I don't see Oregano ever getting there.
As for TTF and PostScript font support, I would like to see them supported by RISC OS as standard, not as some external third-party module.
