What are your favored tools for testing web pages in multiple, and legacy, web browser clients? With tools such as Browserola no longer with us, what do you use - if, indeed, you test your pages outside of the current IE and possibly Firefox versions that is?
I know some people obsess about testing for everything back to Lynx (well it sometimes seems like they do) but how far back do you think it is reasonable to go WRT browser client testing?
