I came across this site yesterday whilst trying to sort out a flash player for mozilla so that my daughter can visit her favourite pages without having to boot back to windows.
ya need to run the browser as root when you visit this page for the "click here to install" to work
result>>> i went to the macromedia site and on to their "site of the day" flash sites and got 100% working pages
haven't seen the "This page needs a shockwave player" dialogue since.
NB/ the plugin from this page is ALPHA, but there is an e-mail link to report bugs
the site infers that it will work for mozilla or netscape (I'm using moz1.3) and there's an added option for a java plugin as well
(Havent tested that-no need, already sorted)
