It is really trippy to see a new Firefox window briefly open with the accidentally dragged tab, after which it immediately gets moved back to the main Firefox window.
Also, enabling tab dragging is temporary (I set the timer to 5 seconds) after which tab dragging is disabled again automatically. This is absolutely brilliant!
So far it seems to work! Thanks Zupffwhy!

Exactly what's needed. Works perfectly. Hooray!

The only thing that bothers me is that the icon for when it is enabled is not transparent like the icon for when it is disabled. Other that it works really great.

Thank you. I was using this one https://addons.mozilla.org/en-GB/firefox/addon/disable-tab-detach/, but it is not working any longer and I searched for an alternative and found this one. Working like a charm so far.

Simple and effective. I was regularly accidentally dragging tabs out of TST. Fixed.

good

fuktioniert super

Очень полезное дополнение. В последних версиях mozilla без этого дополнения совсем работать не возможно. Спасибо разработчикам.

After all these years, Mozilla have finally decided to offer an option to disable tab detach.

Made an account just to give this app 5 stars. I love Firefox, but the drag mechanic is retarded. -.-

Does what it is supposed to perfectly, And that auto re-enable timer? Brilliant. Great job. Fixed a real irritant of accidentally grabbing tabs opening a new window.

At least this i can disable :)

Does what it says, without undoing moving tabs to an existing window, which is something I use a lot. A tinny bit slower than its only "rival", DTD, but not enough to give it four stars.

Does what it should. Thank you for killing that annoying FF feature ^^

I have quickly tested it, and it seems to be working, even with pinned tabs.

Great work.
