Going back to the original post about sites actually crashing browsers...
I do think it is absolutely inexcusable that sites are not properly tested on a good variety of OS's and browsers (obviously it's impossible to test all combinations, but please make and effort!). This especially applies to commercial sites - they seem to take the view that 90% of their audience will be using IE on either Windows or MacOS, so why bother developing the site with anything else in mind?
However, in this case I'd have to say that it has to be either Mozilla or the Flash plugin itself that is primarily at fault - no html, java, Flash etc should be capable of causing the whole browser to just shut down completely like it did when I tried that link (perhaps it's actually a built in safety feature of Mozilla that won't allow you to see content that would offend).
I know that Mozilla is designed to be as compliant as possible with standards and that much of the stuff out there written for IE is extremely poor, but it still should not be capable of actually crashing the browser!
Let's hope little things like that are sorted for the long-awaited 1.0 release!
Oh, and don't even get me started on web sites that don't even *try* to provide any support. The following from a *major* UK catalogue store (don't worry it doesn't crash your browser!):
http://www.argos.co.uk/If you went to that on anything other than IE, all you see is a note saying that support for Netscape rendering engine is coming soon.
It's been like that for at least a year.
There are many more, but that's a particularly good example!
