I also use Workspaces in Vivaldi, and was looking for a way to replicate the experience as best as possible. This tab manager is helping immensely with that.

No complaints. The only "issue" I have has nothing to do with the extension, but with my force of habit.

It's taking me some time to get used to the idea that here I am dealing with tabs grouped not in a single window, but MULTIPLE ones. On Vivaldi all tab groups reside on a single window. I've lost the count of times I've had to use the browser's History to restore the window I've just closed, thinking that I was shutting down the browser. :-)

Thank you for fixing the issue with restoring saved sessions!

This is the best tab manager I've found to try to replicate what I had with Workspaces in Vivaldi. I switched away from Chrome based browsers, so I was lacking some of the awesome features of Vivaldi. The ability to just save windows for later is a part of my workflow and my tabs get out of control without it.

UI is clunky, weirdly implemented, wasteful, unclear and unintuitive. One of the worst out there. Though I'm comparing to ones on a different platform. For me this is unbearable and useless.

absolutely love it

All good except that this extension does not preserve the names of the groups upon restart of the Browser

Working great on Ubuntu 24.04 with Firefox 125. No problems with blank screen or popup.

Is it possible to arrange the tabs by url or alphabetically?

This was my best best Tab manager, but it doesn't work anymore - blank pop up -, how sad.

Ey! Grateful to see you fixed it up! Appreciate it immensely. Edited my review to reflect this on Oct. 26.


[This is what I had written in this originally 1 star review]
[I would gladly give 5 stars - Tab Manager Plus is easily my favorite tab manager out of the lot I've tried. Unfortunately these (*edit) past 2 months (*edit) I only get a blank screen no matter which of the multiple methods I attempt to access my session through - filling my heart with woe.
Compounding that the last time an update was published being 2022 - I'm doubtful it will return. I pray, but I won't be holding my breath on it. Thus; this amazing tool is defunct for Firefox, at least currently...
Still works on Chrome tho - smh]

doesnt work with 3500 tabs

THIS... "Rated 1 out of 5 by liftm, 5 months ago.
6000 tabs open. Popup and sidebar remain plain white even after minutes of waiting."

Just added this extension and have the same issue as liftm. I see that it hasn't been replied to, let alone addressed after 5mos for this user, so I'm not expecting this to ever work for me either. Disappointing experience

This addon was good when I tried it sometime ago. Now I found out I can't move tabs between windows. Drag and drop does not work. I think this same extension is present in chrome. There drag and drop is working fine.

Its good. It has one issue. Where you can't open saved windows. Unless you make the app full screen.

It was working properly in the past, but now it just shows blank page when I open it. At least the counter on the icon works (793 tabs). But it is unable to load them in the add-on's window. I tried to reinstall the addon, but it did not work.

Being Used So Much - Absolutely Love It!
Much appreciated
