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 !

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.

Extension does what it does perfectly. Should be built into Firefox. Mozilla should contact this person and merge it into their Firefox. At the very least they should review its security and then add it to their recommended

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?
