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

6000 tabs open. Popup and sidebar remain plain white even after minutes of waiting.

So much better than the list-based tab managers. No need to scroll through a list to get right to the tab you need. Easily find duplicate tabs. Does what I want.

Working beautifully for me. I tend to gather a lot of tabs while browsing/working. I love how the search function works and consolidates what is filtered into one window to allow for quick removal or reading (depending on the use case).

Well done - only just installed will play a bit more and come back later to donate a cuppa.

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.
