Great addon of all time! Thanks developer for his hard work!
Some differences/problems with 17.0.1:
1. middle-click on link does not group by opener.
2. if tabs searched and FF crash, other tabs are lost in restore!
3. tab bar on LHS, will overlay URL balloon when mouse over link.
Keep up the good work : )
If there are still bugs, just submit issues to Github repo
Although this add-on isn't keeping up with the newest Firefox releases, I am sticking with Firefox 14 just for this add-on. Thank you John Mellor (Jomel) and PikachuEXE!
I think you can use it with Firefox 16
But it's fine staying at older Firefox
Firefox 17 breaks this addon quite a lot and requires at least a few more weeks to fix them all
Not to mention the time to get approved
But you can monitor the Google Group or Google Plus Page if you want to use beta versions
Unfortunately sorting Tabs by domain doesn't work in FF15 :(
also the arrows to scroll through the tabs are gone (really sucks when you have a laptop and no mouse with scroll wheel)
Yup it's not working on FF15
I am trying to fix it = ="
I found a strange thing: if you open second window of FF15, the extension is working properly! But in original window it doesnt work :(
Then I think it's related to some object loading issue
Thank you very much for this info! (I mean it :)
Thanks so much to PikachuEXE for updating this during his limited spare time to work with FF16.0.2 (latest stable at this time.) I wish this became part of the standard Firefox distribution.
Ya I don't even know what happend
Now the tab context menu is moved to the tool menu
They must have rewritten the structure/ID/API
As I am at work now and my main computer's power supply is dead
You might want to stay @ Firefox 14 for a few weeks before I can make it work again
Congrats on the new job. Thanks for what you've done...this is *the* essential FF utility.
On FF 14, which I just installed, the colors/grouping is working but everything is stuck in a single row. Anyone else seen this? I think I'm going to try to backdate, but would rather solve the problem for the current version.
Backdated to 13, no help. What *does* work is to have both TabKit 2nd edition *and* TabMix Plus installed. Multiple rows, TabKit's color grouping available (but not defaulting to when opening a new tab). I'm in a place I can live with.
One other oddness...since the upgrade to FF14 the ability to drag a tab to a new location has been rendered essentially impossible. Movement is possible, but the tab moves to somewhere other than where the pointer is, and the pointer doesn't seem to be under very good control of the cursor.
This is XP, SP3. I haven't seen any Issue numbers, will try to find 56.
I will try to fix that if I can reproduce the problem
Is it Mac only problem?
I'm using the Firefox 13.0.1,
Sometime I open a lot of webpages, so one row is not enough to me.
When I want to open "Option" and change the number of row,
the system shows some strange message
I capped those message as photo,below is the link
Expect that problem,
it is a great Add-on
I especally like it's group in colour function
Please download the latest version at
The Mozilla review is slow so people don't have the latest version yet
Thank you for your work. Only problem is when I place tabs to the right side of my screen, I can't see any tabs. Anyway, pretty good add-on!
**Edit: This is a screenshot so you can see what I meant.
If you look close on the right side of the pic (where the red rectangle is), you barely see the tabs.
The only tab related add-on I have is Colorful Tabs. I disabled that and the issue seems to be resolved. I do like C.T. though.. :( Anyhow, thanks for your response!
If you think it is a serious problem
You can always create an issue with screenshot (so I know better)
If you got some extension you think might cause the problem, just name them
Great to have this addon back!
There is one issue which is bothering me at the moment:
I am also using Zotero plugin and it is not possible to completely close the Zotero pane at the bottom. Clicking the x causes either the tab pane to disappear or the Zotero application tab to open, if it had been opened previously.
Great that you're breathing life into what was one of the best tab management add-ons for Firefox! Still rough around the edges though that will improve over time. It's such an important add-on that I might look into contributing in the future.
可以增加側邊分頁的主題嗎?! 或是CSS EDITOR之類的
還有grouping by domain似乎沒有效
I'm sorry, pop-up support and element hiding helper don't work under Firefox 3.6.*. i highly recommend you upgrade to Firefox 11. Official support for Firefox 3.6 will be dropped in 20 days and obviously i can't support an outdated version of firefox although Firefox 10esr could be an exception.
I've been waiting and waiting and waiting to upgrade Firefox, for the sole reason that there was no TabKit. Fixed -- thank you!
This is exactly why I take the project
To allow MYSELF to upgrade my Firefox
Distributing it is just a bonus :P
Please, check multiple rows then tab bar at the bottom. Then tab bar at the bottom, only one row is showing.
I have tested in Fx 10 with clear profile.
Could you also create an issue on Google Code so that people (including me) can track it?
It's really wonderful to have the features of Tab Kit back once again. I am one of the many who delayed upgrading from FF 3.6 due to a lack of an upgrade for this add-on. I finally gave up and upgraded a few months ago, but there's really no substitute for Tab Kit, which works perfectly for me under FF 11. Thanks again!
Suggestion: Would it be possible to have an option not to make the current tab's title bold when highlighted?
I am happy to see that people can upgrade their Firefox without the absence of great extensions :)
I upgrade it since I was also stuck by the original Tab Kit LOL.
There is already an option in "Option" -> "Tabs" Tab -> "Make Current Tab Text Bold". Just un-check it!
The reason why I am using this add-on is solely for the parent/child hierarchy coloured tabs. And I must say that they work great!
-Why is the panorama feature disabled? We should have the option to use it, so I don't see a good reason on why it should be left unsupported. You say: 'Why use Panorama when you have Tabkit?' I say: Why not have the best of both worlds? :)
-The current tab shouldn't be highlighted when you hover over it with the mouse, it should be left static. (It just makes it that much easier to recognize what tab you are currently on.)
-I personally think that the colours in ColorfulTabs look better. Perhaps you could provide us with more colour options so we can mess around with what colours we want to use, and in what order maybe?
Ok the last two were just nitpicking, but if the panorama feature is supported then this add-on will deserve 5 stars.
1) I am sorry but panorama and TK2 both use the same API of tab which will mess up the tab grouping feature much.
2) It is the behaviour of TK1, maybe I will provide an option later.
3) After bug fix maybe...
does not work the middle mouse button (open links in new tab)
Please submit an issue @
So that I can track it
multi-rows not work on 9 firefox (((((((
Created a new profile and set up everything from scratch. Earned!
And have not found an application that conflicts with the TabKit 2nd Edition (((
Thank you for the resurrection of the old application!
Please make a forced single window mode (ctrl + N and a new tab)
Please see if there is an existing issue for this
@ Google Code Site
Needs to be updated, but you can get it to work by simply installing this add-on to stop the compatibility check:
In fact I just uploaded a new version declaring compatibility up to 20.* lol
But Moz system rejects XD
I will add the addon info to the project page, thx
Not available for FF 9.0.1 yet, but I'll be keeping my eyes peeled. It's incredibly hard to work without this once you've used it.
But the declaration is not updated yet lol
Also I am still waiting for the result of Mozilla review
If I upload a new version I need to wait for much longer time
Please check two more features:
2. Is it compatible with ColorfulTabs?
1) It is already there and working!
You can check the option->control->hover
Middle click as mentioned is default behavior of FF already
2) Compatibility with other extensions is the last thing to be considered.
And is that you want the colors of colorful tabs to overwrite TK2's?
The original Tab Kit was the only reason why I stayed with Fx3.6 for so long.
TabKit 2nd Edition still has work to be done, but offers functionality like no other extension. Grouping and coloring tabs saves me at least an hour of confusion every day.
It would be better if there are some helpers...= ="
Love TabKit and was excited to see a version that would work with newer versions of Firefox.
Just 2 annoyances/things I think are missing, but not sure if I'm somehow just missing them in the options menu:
1) Keep the left hand tab list expanded (I don't want it to shrink everytime it loses focus or I click off Firefox!)
2) I frequently used the "Add Tab" + button that appeared beneath all of the tabs and would like that functionality back.
1) Do you mean vertical tab bar collapse all the time?
There is a button at the center of the re-sizable border
2) I am not sure how it works right now, could you write it down @ http://code.google.com/p/tabkit-2nd-edition/issues/list so I can track it?
Thanks a lot!
TabKit 2nd Edition 0.9.7.62,
Chinese language error, unable to open the options.Thank update.
But I need helpers for the translation...
Thank you very much for updating this addon! Finding this is the reason I finally upgraded from FF3.6 to FF8.
The only problem I have with this that I didn't with the original deals with compatibility with Faviconize Tab (https://addons.mozilla.org/en-US/firefox/addon/faviconizetab/). The original TabKit had some issues with it, but somehow seemed to kind of ignore Faviconize. This version of TabKit does not do that. When I double click an expanded group to close it, it also faviconizes the tab. The old TabKit would just collapse the group but not shrink the tab.
I'm not sure how this could be changed, but I wish it could be so I don't have to change faviconize to another shortcut. Maybe a button to collapse a group could be added to the rightmost tab in the group (like how there is an expand button when it is collapsed?)
I am not sure why it would occur
Can you please write an issue report at
There are quite a lot of changes made due to FF4+ structural changes
So it is quite possible if it somehow affects other extensions...
I would look into it when I have other critical bugs fixed~
