The most simple way of grabbing a list of your current open tabs (their urls), across windows.
***Grab Tabs is Super Simple
This is a super simple extension which dumps a list of current tabs to a text box, ready to copy out to wherever.
There's no need for complexity, sometimes you just need a list of the urls you have open, across windows - essential functionality for a lot of us power users.
Session managers are great, (I use the extension called Session Manager) - but they still lack just the brute functionality to get a list of tab urls straight out. This does that.
No frill, simple tab url extraction :D
