Just what I wanted.

Tweaks: I set it up so that I have the TMP icon on toolbar that opens a TMP *view* in a new tab (which as a view you can delete after using without deleting its contents) and set to small ("eliminate spaces around"). Then you can see all the windows panoptically and can move documents easily between them.

DO NOT PRESS THE "X" IN THE RED CIRCLE unless you want to delete the whole individual window. Instead, to delete tabs within a window, right-click the tab icons, select as many as you want, then go to the trash can at the TMP tab to click and delete.

The "save" feature works. Though will it if I close Firefox? Time will tell.

If I leave the main TPM view (e.g. to change the name of a window), pressing window refresh gets me back to the main view.

Confusing UI. Features are poorly explained & don't feel very well thought out to me. Import only accepts JSON but no explanation of what the key names need to be in your JSON. Since this is a very old extension, hard to imagine it getting better now.

like the shortcut to switch to any tab (similar to what chrome has) the interface could be cleaned up a little bit. Interesting that not many people are using this extension and it's not monitored by mozilla for security.

Great add! Keep it up!!

If you are one who ends up with many tabs open at one time like I do, you will love this extension. One feature I love is that you can find duplicates and drag the group all at once to the end to close the ones you don't need. It's a wonderful app!

I love it and use it all the time.

Save tabs for later option does not restore tabs.

Best add-on i've ever added to my browser!

i switched to firefox a couple of month ago from Chrome, i used this add-on on chrome, and im so happy to see it's here as well.

I use TMP in the sidebar in vertical-view.
A function "Open in sidebar by default" (like "open in own tab by default"), so that a click on the TMP icon opens and closes the sidebar with TMP, would improve this usage a lot!

This extension changed my live, literally! My Tab related problems are all gone and I'm saving lots of RAM, which speeds up my PC!

I've used plenty of tab manager extensions, nothing offers me the ease of use and productivity boost that this one does!
Particularly love being able to clump tabs together into different windows and name them, as well as color code them, for easy identification and switching.
For someone who regularly has 300 tabs open and gets frustrated easily, this extension is a lifesaver :)

These screenshots show a search function and other icon options to the right of that search function. For some reason my Plus is not giving me the option to search or group tabs like I'm seeing in these screenshots making it not nearly as useful as it could be. Can someone point me in the right direction as to what I'm doing wrong? Thx.

Efficient, useful and tiny footprint!
