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.

fait le job , proprement et simplement. un bon module.

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. -.-

This is exactly what I needed. Firefox has been automatically tearing tabs to new windows with frustrating frequency. This extension solved the problem.

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.
