This is pretty cool. I did not know this but you can drag and drop a tab from Firefox to view the same page in Google Chrome. No need to copy and paste to try see what it looks like in Google Chrome.
Move your mouse to a tab in Firefox, click and move the mouse to Google Chrome. Release the left button and your webpage is now opens up in Google Chrome. It does not open a new tab, it replaces the contents of the current tab that is open.
I have not been able to drag a tab from Chrome to Firefox though...
