Does not work on FF 46.0.1 and Mac Rated 1 out of 5 stars

Does not work at all and seems to be abandoned.

Doesn't work at all Rated 2 out of 5 stars

When I drag one or more tabs to a group, it makes a group with the name of each tab, each saying that there are zero tabs in it. In other words it's useless. Does anyone know if this bug has to do with the discontinuing that people write about (I'm a new user), or is it Mac related or maybe related to another plug-in?

I leave it two stars instead of one, because people seem to love this add-on, but I didn't want to give more stars to something that is completely broken for me.

Reborn as Tabgroups Manager revived Rated 5 out of 5 stars

This extension is awesome, but will probably stop working in the near future due to lack of extension signing.

For those who are unaware, this extension has been reborn as a new extension, see https://addons.mozilla.org/firefox/addon/tabgroups-manager-revived

Bestes FF Plugin Rated 5 out of 5 stars

Dieses Tool ist eigentlich noch der einzige Grund warum ich den FF verwendet - ansonsten würde ich wohl auf Chrome umsteigen. Die Art der Organisation von Tabs in Gruppen ist m.E. genial. Die Gruppen sind Themen/Bereiche zu denen es viele Fenster gibt.
Leider stockt die Entwicklung und es gibt öfter Probleme mit neuen FF Versionen. Eine Kontaktaufnahme zu den Entwicklern (wenn es denn noch welche gibt) ist leider gescheitert - ich würde das Projekt tatkräftig unterstützen. Genial wäre es wenn die Funktion des TGM in den FF Standard aufgenommen würde.

When this stops to work i will abbandon FF Rated 5 out of 5 stars

This addon is the only reason i use FF. A new version was found before on another site *some google code site* (from another developer) but even that has stopped since google closed that code site.

Leaving firefox? Rated 5 out of 5 stars

The developers are continuing to follow others such as MS in deciding what is best for their users.
I use this add-on hourly, and controlling add-ons without options which I want to use is not really what I want or need - so like thousands of others for me it may have to be GOODBYE to Firefox.

This add-on is only reason why I use FirefoX!! Rated 5 out of 5 stars

To override the unsigned addon thingy and get this to work:

in browser go to about:config and enter this:

Right click,choose New boolean,type---> xpinstall.signatures.required
and set it to false (should default to false)

Great plugin, Asshole Mozilla Rated 5 out of 5 stars

You could disable verification Rated 5 out of 5 stars

From docs : https://wiki.mozilla.org/Add-ons/Extension_Signing
"Check the Firefox Release Calendar for specific dates. The following timelines are for Desktop:

Firefox 40-42: Firefox warns about signatures but doesn't enforce them.
Firefox 43: Firefox will have a preference that allows signature enforcement to be disabled (xpinstall.signatures.required in about:config).
Firefox 44: Release and Beta versions of Firefox will not allow unsigned extensions to be installed, with no override.

What are my options if I want to install unsigned extensions in Firefox?

The Developer Edition and Nightly versions of Firefox will have a setting to disable signature enforcement. There will also be special unbranded versions of Release and Beta that will have this setting, so that add-on developers can work on their add-ons without having to sign every build. To disable signature checks, you will need to set the xpinstall.signatures.required preference to "false".
type about:config into the URL bar in Firefox
in the Search box type xpinstall.signatures.required
double-click the preference, or right-click and selected "Toggle", to set it to false.
"

Working well.

We need an answer from Mozilla Rated 5 out of 5 stars

Hi ultrafox, we are waiting for an answer from Mozilla in the following topic:
https://discourse.mozilla-community.org/t/development-and-maintenance-of-tabgroupsmanager-extension/5935

Or if someone knows a direct way to contact Mozilla (email or phone), we would be glad to talk with them to solve the maintenance of this extension from AMO.

Be careful if you use Session Manager! Rated 2 out of 5 stars

I installed this in the hope it would make tab groups useful and it more or less does, but after restarting to activate some changes in preferences I found it didn’t reload the session. There is a setting which *might* make it work with Session Manager but the wording is unclear. Session Manager had also only saved one backup for some reason for after setting the Compatibility and restarting I now have no session to restore. After carefully sorting some of about 200 tabs they are now all gone. I’d like to give this more stars, but that’s not good compatibility.

EDIT: I was wrong - I don’t have Session Manager installed these days, it’s Tab Mix Plus which has a Session Manager component.

But now I’ve noticed that TGM behaves strangely in other ways. Every time I click on a tab group tab it opens another blank tab in that group. As much as it looks like what I want I think I’ll have to uninstall it as it just isn’t usable if it’s doing things like that.

It’s also unclear if this will be completely dead after Mozilla remove the groups feature.

Ctrl-Tab Rated 5 out of 5 stars

When TabGroups Manager enabled, doesn't work switching between tabs with preview by Ctrl-Tab (when about:config option browser.ctrlTab.previews set to true).

FF 43 release is looming over our heads Rated 5 out of 5 stars

Guys, we need to get the working addon verified or we risk loosing all our tabs when FireFox 43 comes since it will disable all unverified addons then.

No funciona Rated 1 out of 5 stars

Uso Fedora 22 y Firefox 41.0.2 y no funciona se crea la pestaña de grupo y al tratar de poner páginas no las pone...

so useful Rated 5 out of 5 stars

I always have (too!) many tabs opened and this addon saved me, I disagree with other rewiews: it works perfectly for me, customization and everything else. I also have session manager installed and never lost a tab.

Essential add-on Rated 5 out of 5 stars

To those having problems, make sure you download the latest release here:

https://code.google.com/p/tabgroupsmanager/

It's working fine with FF41.01.

Not working the way you want it. Rated 1 out of 5 stars

Too much useless options as well.

...Issues... Rated 1 out of 5 stars

Well I installed it, and tried to use it for a couple days. The add-on would be amazing IF it worked. You can't (re)organize tabs into the groups. It sometimes puts some tabs in some groups, but I can't move tabs to different groups by dragging and dropping. Also, some tabs don't belong to a group, and I can't add them to a group. A really good start, but the bugs are killing it. I have to uninstall. There are some other Group add-ons that work better.

Tab Groups Manager Add-on started behaving erratically since I upgraded to Firefox 39.0 Beta version. Rated 1 out of 5 stars

Tab Groups Manager Add-on started behaving erratically since I upgraded to Firefox 37.0 Beta version.

Tab Groups Manager shows all the Groups that I had created. But as you can see all the Tabs that were in different Tab Groups are now displayed in a single group and I am unable to arrange them in groups like I used to, i e, before upgrade. My earlier FF version was 34.5 Beta, now it is Firefox 39.0 Beta. Such problems have become pretty routine with new version coming out every other day. Earlier I used Tab Groups Menu, which was very helpful, but that simple stopped working with newer versions. So I was forced to abandon it. Now the same thing is happening with Tab Groups Manager. How can use My Firefox if this continues?

автор забросил это расширение Rated 1 out of 5 stars

К моему большому разочарованию это дополнение дает ошибку. При открытии новой группы вкладки которые были в предыдущей копируются в новую группу, а в предыдущей еще открываются новые (пустые) вкладки сами по себе. Хотела написать на сайт разработчика, но сайта нет :(
Раньше все было нормально. Очень жаль, поскольку дополнение очень хорошее. Может это только у меня? Я пользуюсь 17 мозилой, не перехожу по определенным мотивам, но раньше таких проблем не было даже в более ранних версиях мозилы.
