I feel like I have found the perfect replacement of Tab Panaroma feature, This is the only one I found that allows you to drag and drop a group of tabs into it's own separate group. Although you do need to Ctrl+Click on each tab individually instead of Shift+Clicking the first and last tab which should select all tabs in between.

It is great! Love the load/unload/stash options for the groups, it's what made me stick with this add on.
One annoying thing though, that keeps me from giving 5 stars, is that if I click on a pinned tab it automatically switches to the group I originally opened it in, rather than staying in the group I am currently in.

Edit: And now it's fixed, great timing, thanks!

This is a great add-on but v0.16.6 has bugs.
#1. Click on icon > dropdown menu with groups opened > select an item > nothing happens! (now if you click on icon again an empty menu opened. additionally F2 not working and the settings page has broken items).
#2. Restart Firefox and press F2 > page with groups opened successfully > click on a Tab from another saved Tab group > Firefox switched to this group normally (now again icon menu, F2 and settings page broken like #1 above).
#3. I had no problems at all using versions before 0.16.6.
#4. FYI i am also using "Temporary containers v0.91" add-on (installed months before this add-on).


EDIT: Yes it is fixed in 0.16.7 - Thanks for quick responce - B. Regards

This is simply awesome! Thank you very much for working on this addon.

Great minimalist tab groups extension.
Offers a nice and simple UI without all the bells and whistles which i don't need.

The only thing that i'd really like to see added is a "send to group" tab context menu option.
