By far the only feature packed tab manager that has what you would expect a tab manager to have and not be annoying about it. Being able to switch the view style of the tabs being managed in the popup or its own tab is a really nice addition that makes it far more user friendly than the many alternatives I have used. It also was extremely self explanatory to use, there was no need to dive into Github issues just to figure out how to use the thing. Most importantly, it includes the experimental feature to save sessions that so far is working well and means that I can eliminate other extensions than just other tab managers with this one, which I like as having too many extensions makes me a bit nervous in terms of long term sustainability of my workflow.

My only gripe with this extension is cosmetic, I would like to be able to control the background and foreground colors in dark mode as the default is not my favorite. That's not worth a star though.

For automatic opening of a sidebar in ALL THE WINDOWS even one star is too much.

not compatible with window 11?

Absolutely stellar. I can see the tabs and manipulate them at will. Just need to explain to some users the existence certain tips and tricks like ctrl+left click or dragging between lists and it'll be just what I'd want.

Tab Manager is a brilliant piece of software/add-on, I use it continually for finding pages, searching for information and just leave useful tabs open and use it as an excellent search on my history.

I really push the software, at the moment over 2300 pages/tabs open in firefox, one window! Doing a search on all open tabs usually find the page I looking for and if wanted can open a group of tabs in another window and know all the pages open are probably useful, it's like an intelligent favourites from the browser history. Many thanks Markus and best wishes from the UK and other software developers.

Good extension with some peculiarities. Opening of saved sessions don't work from pop-up, but only from tab menu.

I downloaded and installed Tab Manager Plus for Firefox last week. I sorted through about 150 tabs the manager seamed to be what I needed. I had 4 windows open that I was sorting into named Hobie's, Financials. Truck stuff, and General where I was keeping tabs that didn't fit the other three. I got tabs the way I wanted them and decided to see what happens when I turn off Firefox. When I restarted the tab that I called General was gone and with it all of the tabs in it. What did I do wrong? Is there any way to get them back? I tried the history but there are only a few from that window. I tried to rebuild the window with what I had then restarted again. Once again the General window was gone. This program looks like just what I need. It also likes to delete the names that I assign to different windows. I just recently had a power outage and once again the General window was gone! What am I doing wrong? I just had to restart my computer and now i have lost another group. I'm getting rid of this thing! If I wanted to reduce the number of tabs I would have just deleted them myself.

Great app with a lot of potential and I am using it all the time. But there is a massive bug. When I close the firefox and reopen it, all the tabs names are shifted and randomly allocated to one another and I have to go one by one and set the correct names againg which is very, very painful. Please, for the love of humanity solve it.

BEST EXTENSION EVER!! It got all the fundamental settings, but also the fancy stuff. I like that you shipped itwthout all the extrta featurtes active. Splednid!

Just installed this extension for searching-finding tabs in "containers" among hundreds of open tabs across many browser windows as suggested by someone over in the support forums.

I only need this BECAUSE I have those hundreds of open tabs (though I seriously need to tidy up!).

See: https://support.mozilla.org/en-US/questions/1360159#answer-1465135

However (per that posting), it seems to have introduced an overall sluggishness, hesitation and slowed responsiveness to using Firefox. Perhaps an update could address this?

Otherwise, a nice find -- thanks!


(later today, after many hours of browsing)

Unfortunately, I have disabled (not yet removed) this extension as I've grown tired of the performance impact due to constant hesitations and long load times of new web pages, when scrolling, switching tabs, etc.

Perhaps it works acceptably for those with far fewer tabs. Too bad for me, though...

Won't stay pinned on all tabs, tried with active-pinned-tab but that other add-on doesn't work properly either. Makes it very hard to use.
