(Possibly might let you do an end-run around the OS version requirements for a newer flash version? ) I used it to switch my Flash version back to 7, and it did so without running an Adobe installer, or if it did use one, it was 'silent'. I downloaded a FF2 compatible version of 'Flash Switcher' and it seems to work under 98, even though the author's website said it had only been tested under XP. (I recall seeing a website where someone had managed to get FF2 running on 95) I don't have a 95 test system set up at the moment.
I did some searching and experimenting here on my 98SE/FF 2.0.0.20 system. I wonder if it would be possible to spoof the flash version reported to the website, just like how the User Agent Switcher can report a newer version of Firefox? I have a feeling this is a 'false incompatibility' they have introduced.
