This used to be great but the option to add the toolbar is missing from the context menu so there is no actual way to use it. Don't know why. I used it years ago.

Great tool. Simple to use and does the job super fast. However, please write the instructions on how to use it as I always spend at least 10mins trying to figure it out.

Great addon. But needs one improvement. Should have an option to have a confirmation dialog or not. Considering it's position in the dialog directly below one other addon I use, I accidentally clicked on it when I didn't want to, and had to separate the windows again.

works without issue

worked like a charm!

Very useful for cleaning up after a long research session!

I often forget how to run the extension. The "Merge all windows" action is available in the context menu of any tab when multiple windows are open. I expect to find it in the "Window" menu, but I imagine that is not accessible to add-ons.

HOW-TO-USE: Right-click on ANY tab. The "Merge all windows" should appear near the bottom of the list. Thanks for this simple BUT WELL-NEEDED Practical add-on !

Awesome idea.

GOOD

Merging windows is a simple task, but automatizing it makes life a bit easier. This addon does the job perfectly, there's nothing I can think of to improve it.

Merging Firefox windows without toolbars with the main window breaks scrolling in the merged tab.

Surprised why this isn't a feature in Firefox by default.
Extension does what it is supposed to pretty well!

It works as advertised and it's open-source. What do you want more?
