Rated 5 out of 5 stars

This. Is. Great. Thanks a lot.

As for Mateusz Czapliński's issue/question (I hope he reads this), you can try using an extension called Menu Editor to move the menu option around menus as you please. Only shortcoming is that you can't actually have the option in the tab context menu and in the file menu at the same time, but you can move it to the file menu or any other menu if you want.

Es fantastico!! Hace mucho tiempo que buscaba algo así!! Está también es español y se integra perfectamente con Firefox. Totalmente recomentado.

Rated 5 out of 5 stars

Wonderful extension. One small issue is that when I have one tab left, the tab-bar usually disappears (with Fx's default settings), therefore I can't access the "join" option anymore. Would that be possible to add this option to the page's context menu for example?

Needs to move history Rated 4 out of 5 stars

Seems to work fine, but I agree with the last reviewer - if the new window could have the same History as the original window, it would be perfect!

minor flaw Rated 4 out of 5 stars

I really love this idea. The only problem is that when the new window opens, it no longer has the back/forward pages of the original tab. Fix that and you've got an awesome add-on!

Most Excellent Rated 4 out of 5 stars

I've long felt this to be a key missing function in Firefox, so am very grateful to have found your extension!!!

Works perfectly Rated 5 out of 5 stars

This is pretty basic extension; it does exactly what it's meant to. Thanks for this. I was surprised that there's no tab to window functionality built into Firefox.

Thanks! Rated 5 out of 5 stars

I hate to spend time writing reviews, but today I decided to disable "Tab to window" just to see what it was doing... That was a panic. I could not continue my browsing session without enabling again and restart FF. And I spent 10mn registering on FF to make the review...
Great little add-on, unobtrusive, that makes life easier during intense browsing!
