Brilliant. I had 109 tabs open and I could not find a fast and easy way to move them to my new PC ... until I found this extension. Simple-as extension, pure gold in my case. Go, install it to see what it can do for you.
It looks scary at first as it closes all tabs and presents you with 1 page full with the URLs but you can easily restore. Or in my case export which is in txt format, then I wrote a draft email, opened the draft on my new PC, copy&paste into OneTab's import window, done. OneHappyDude :)
