how can i install multiple version of a certain browser?

I need to install multiple version of Firefox, say versions 3.3 and 3.5 and Internet Explorer 6 and IE7 & IE8.

Is that doable? how?

Thanks

 

To install multiple version of Internet Explorer use Internet Explorer Collection

 

Install linux and run WINE

 

bitist post is very interesting. However you can also do that with a virtualisation software like Microsoft Virtual PC or VirtualBox.

 

You can use virtual PC...

 

If you have time you can install VMWare + ThinApp and make your own Portable Browser and you can keep it as yours.

 

If you need it to make Cross Browser Compatibility tests, try to search for websites like browsershots.org - they make the test online for you ;-)

 

I agree with noface83. You can install VMWare then you'll be able to do a few OS concurrent. The one site you can install Firefox 3.3 and in VMWare Firefox 3.5.

Thanks.
