If you mistakenly put backslashes in your relative hyperlinks, IE silently replaces them with forward slashes. Does IE do this on Macs I wonder? It seems a very DOS-centric way of doing things. This is not “embrace and extend”. This is “be nice to sloppy people, breaking it for everybody else”. Firefox doesn’t like backslashes, correctly replacing them with %5C and then choking.
Meanwhile, MS has released a developer’s toolbar for IE (beta). I don’t normally use IE, but I had a quick look. WTF — it requires a complete system reboot to take effect. It looks like it has some handy features, but boy, it’s a bit buggy… try and view table outlines, and it takes ages if there’s more than a handful. Not so good.
Frankly, the Firefox web developer extension craps all over it.
