I found this at sitepoint and thought I migth share it with you all.
Some of the more
popular browsers
For cross platform older browser versions, check out the
evolt browser archives.
Browsercam offers screen captures. It is a commercial service, however it offers a free trial.
You can run all these browsers on a single Windows XP installation:
Mozilla (any version, and all versions at the same time is actually possible)
Mozilla Firefox
IE 6.0
IE 5.5
IE 5.0
IE 4.0
IE 3.0
Opera 7.x
Opera 8.x
Netscape 6 or 7 (perhaps both can be installed next to each other, I'm not sure)
IE 3-5 downloadable here.
For these browsers you'll need either a linux machine or Knoppix (= Linux emulation under Windows):
Konqueror
Linux versions of Mozilla and Firefox (they differ!)
Ghaleon
For these you need a Mac OS:
Safari - However
there is a website that lets you see it on Windows.
Omniweb
IE 5.2/Mac
Kamino
Firefox for Mac OS (also has differences, esp. concerning form fields and their styling)
