Looking for substitute for TabKit 2nd Edition

Hi:

I'm not familiar with that particular extension, but it is being evaluated for official hosting at AMO:
https://addons.mozilla.org/en-US/fir...dition/?src=ss

If you are not comfortable installing it before it is officially approved, you might look for something similar here:
https://addons.mozilla.org/en-US/fir...tensions/tabs/

Another strategy would be to create a new, test profile in Firefox, to try it out so that you do not risk breaking your main profile - these articles might help a bit:
Creating a new Firefox profile on Windows - MozillaZine Knowledge Base
Transferring data to a new profile - Firefox - MozillaZine Knowledge Base
Profile Manager - MozillaZine Knowledge Base
Profile backup - MozillaZine Knowledge Base

Another strategy might be to try TabKit 2nd edition in Firefox portable.

Hope this helps,

MM

I tried Tree Style Tab.

Here's how it looks in Cyberfox.

Note: It broke "Menu Bar" that could not be restored until the addon was removed. Maybe that's a non issue if you know how to access bookmarks and addons manager.
