You may view several sites in your browser in several tabs. What if you need to have side by side two or more of these sites?

Tabs are not convenient in this case, it would be better to have those sites open in different browser instances.

You can do this easily. Just drag a tab and drop it in an empty Desktop space!

This tab becomes instantly a separate browser window! Now just place the two windows side by side to enjoy simultaneous monitoring of both of these sites you are interested in.

Enjoy!
