  • Tab Groups and other disappearing addons is why I preferred Firefox. Thank you, developers.
    For anyone interested, I found a native Firefox workaround for Tab Groups and Tab Groups Menu. --> http://attic.e-motiv.net/fyi/tab-groups-workaround
  • "This add-on is not compatible with your version of Firefox".
  • ...not working :(
  • Does not work at all and seems to be abandoned.
  • 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.
  • 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
  • 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.
  • 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.
  • 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.
  • 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)
  • This is the ONLY reason why I use Firefox, and now that Mozilla decided to fuck me upp the ass I now have to restort to sticking to an old version.

  • 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.
  • Hi ultrafox, we are waiting for an answer from Mozilla in the following topic:

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


    It's working fine with FF41.01.
  • Too much useless options as well.
  • 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 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?
  • 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.
  • Ich benutze das Addon nun schon seit vielen Jahren. Ich kann mir gar nicht mehr vorstellen ohne zu surfen. Man gewöhnt sich echt schnell daran immer die wichtigsten Tabs in Gruppen Tabs sortiert zu haben und so schnell auf alles zugreifen zu können. Vor allem wenn man wie ich vielerlei unabhängige Interessen hat, ist wunderbar hier einzelne Gruppen Tabs zu haben.

    Bin echt froh, dass das Addon inoffiziell weitergeführt wird und so auch unter der neusten FF Version einwandfrei funktioniert. Aktuell hab ich bisher keinerlei Probleme feststellen können, früher gab es immer mal ein paar Probleme mit dem Popup Menü des Addons über den Tabs, sind aber mit der letzten Beta verschwunden. Ich hoffe das Addon wird noch lange supported.

    Hatte auch schon nach Alternativen gesucht, aber nichts ähnliches gefunden, das mir so gut gefällt wie dieses Addon. Man sollte es zudem mit dem Addon "Session Manager" von Michael Kraft nutzen, damit hat man immer Backups aller Tabs für den Fall der Fälle.

    Und damit es nicht untergeht hier noch mal die URL zu den inoffizellen Updates:

    Here is the Link to the newest unofficial Version:


  • Ich nutze etwa 25 TabGruppen mit über 300 Seiten unter FF 31.2.0 ESR und Win8.1.
    Vor der Installation des AddOn habe meinen FireFox Profilordner gesichert! Sicher ist sicher ;)
    Nach der Installation erschien eine neue Leiste, mit nur einer TabGruppe darin :( Oh Schreck, alle Gruppen weg?
    Ein Klick auf das alte TabGruppen Icon brachte aber alle Gruppen wie gehabt zu Tage und :D
    die neue TabGruppenLeiste füllte sich nun mit den Gruppen :D
    Alles läuft wie gewünscht. Super. Danke.
