Absolutely amazing extension for organizing tabs. I have tried dozens if not hundreds of tab management extensions in the past. This is my clear #1 favorite.

Fantastic extension. All it needs is a customizable command to skip the right click menu. Would it be possible to replace middle click on a link? Or add a use modifier key + left click? Or something that can be mapped to the thumb buttons? Thanks!

agree this addon needs a function to create the 2nd window if there is no secondary window currently activated when toolbar button is clicked. will change to 5* when implemented

I think I would love it were it able to create a new window AND move to it if no second window was yet opened. For now, using Popup Window addon.

This extension is a Godsend. I have been wanting this feature in browsers for years and they still have added it. I'm not sure why but until then, this extension is perfect!

The add-on is fantastic. In chrome I've used an extension called "Spaces" which is very similar, and now moving to Firefox I need to find a way to move tabs between windows and to name windows. Having names is great, easily choosing which window is great. Allowing you to switch to that window when sending a tab or with a right click is great.

Two improvements I'd like, the latter which might not even be possible.
1. I would like to send and switch using only the keyboard. I can almost do it with like 8 clicks, but that's silly. I've also learned it's surprisingly impossible to open the tab context menu with keyboard only.

2. Switching windows doesn't work so well with mac workspaces. Most of the time when I send a tab to a new window, I'll also switch to that window, no matter the workspace. But if I do the right click window switch, it only works if the windows are in the same workspace.

Easy to use and works flawlessly!
Super useful for my triple monitor setup!
Thank you for the addon!

This addon is a really great concept and just what I needed, however I would rate 5 stars if there was a 'move to other window' option on the context menu of each tab. At present it's pretty slow to move multiple tabs to another window, or move a tab which is on the opposite side of the browser window to the 'Other Win' button.

Also, often, when Ieft click on the 'Other Win' button in '2 Window' mode, it swaps to the destination window and stays there, while other times it stays on the source window.

good! it is that i need! i don't understand why is not in default feature browser.

Does what I wanted! Would be nice if I could name my windows so that I could easier recognize them.

Edit:
Thank you! I am using the new naming feature now and so far it is really helpful. Some other extensions use a window's current tab's title as the window's name but I like naming the windows better. This is probably my favorite way of switching windows currently and it works really well.
