Recently, I've been tweaking my blog and came across this cool site that let me see my blog in different browsers.
I can check if my blog looks all right in dozens of browsers on this site. It will display screen shots of the results.
As it really isn't practical to install every browser out there, this site really helps to speed things up a little.
The downside is the site takes a long time to load, so just choose the popular browsers to reduce the loading time.
Hope you will find it useful, here's the link:
