Tools: Check your website on multiple browsers

"Browsershots
is a free online platform where you can
test your web design in different
browsers[, including several versions of
IE and Firefox]. When you submit your
web address, it will be added to the job
queue. A number of distributed
computers will automatically open your
website in their browser. Then they will
make screenshots and upload them to
the central server here." -- from the
