IETester: an all-in-one Internet Explorer testing suite

It seems as if someone has finally cracked the problem of running multiple standalone versions of Internet Explorer under Vista.


IETester is a web browser that can run the IE5.5, IE6, IE7, and IE8.1beta rendering engines in the same process. It has a tabbed interface which makes switching between different IE versions a snap, and although it is only an alpha release it seems to work fairly well.

Personally, I’m still a fan of running IE6 in VirtualPC, using the virtual machine provided by Microsoft specifically for this purpose. No quirks or bugs, just the real IE6 running within a real Windows XP installation. But if for some reason you can’t or won’t run VPC, IETester provides a workable approach to testing in IE6 & 7 side-by-side.

    Looks good.
    Will have to download and have a look.

    For me I want a simple solution without having to run a virtual PC or have an extra browser.
    Thanks for the information

    I like the VirtualPC better, except that the one Vista PC we have here, is running Vista Home Basic. Unfortunately, you need at least Vista Business to run VirtualPC. So this is a pretty nice solution.

    I use this all the time – but it does have some bugs. Occasionally when testing in IE6, you’ll open up a site and see something that looks completely out of place for no reason – but once you open up the Debugger bar (I think it’s a separate download, but very helpful) – the out of place element snaps back into place. Just something to keep in mind if you use it.
