I first discovered the excitement of XSS stuff with Firefox and one of the infinite number of plugins.... :-) fortunately, I can disable the XSS checking for specific sites such as Mudcat now...

Still using FF V3 - on Facebook a certain game Castle Age just stopped working reliably in FF (Ubuntu system) - some pages won't even open, some links won't work. etc. Not even in the version of IE on Win 7 on the laptop, same nonsense. But it only works fine in Chrome on both systems.

One might think that there would be a way to tell IE to stop farting around with the XSS stuff for certain sites, but I think you might need a cut lunch and a compass to go exploring, if MS deemed that their users were intelligent enough to want to ...
