Спасибо тебе добрый человек, люто бесит это открепление в новые окна.

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

I found discussions regarding this "tear-off tabs" issue going back several years. Firefox should have the ability to disable tear-off tabs already built-in to the settings. This solves the problem! Thank you for making this extension!

This need to all browsers!

This is my favorite addon now.

Love it.

Seems like Tab detach has been annoying people for a few years. This just started to happen to me the past few months. So happy to have this add on to disable this horrible feature.

Thank you for a great solution to a nagging problem. I have one question. Why does this extension add a line to the page actions (3-dot) menu?

Thank you for providing that!

The plugin works flawless and does what it should.
