Magnifico ! Coupled with New tab suspender extension it's a memory saver and performance guarantee.

Brilliant extention. Only downside is that it encourages you to hoard Tabs. Is that such a bad thing though? I can archive them and they wont be in memory anymore.

Took a little to figure out how to use it. I would suggest setting up the hot keys to switch between groups.

I think it works best combined with containers. You can use this with containers to insure you always open the right containers and you can auto group websites into groups/containers

simple and great!

Changed the way I use my browser. It is incredible! You should use it.

This is an amazing addon that, together with the Tree Style Tab, keeps my sanity with all the tabs and containers open.

Is there anyway for us to add a hotkey to open STG on sidebar? Currently, I have to do Ctrl+B then browse for STG which quite not productive

Just perfect!

Deleted all of my saved tabs after using for a few months. Restore previous session option is enabled and had not issues until everything was gone one day. No way to backup or restore that I could find.

I'm interested in using this addon but mostly was hoping it could put pinned tabs into a group. Is this possible?

Very useful, but occasional dysfunctions.

So far so good! Completly changes expirience for the better! Thanks

Great product and really happy with the functionality. Just changing to a new PC - and trying to get my hundreds of tabs moved across. Simply copying the backup file doesn' seem to work. Is there a method?

I have about 760 tabs in my session. I worked for an hour and a half with this add-on to set up my groups, and when I reopened FireFox, it had erased all of my work. This add-on thrashed my tabs, then refused to show the management screen. I could see it blink on, then disappear. Sadly, this add-on doesn't work with large tab sets. Good thing I backed up.
[edit] Yes, session restore is enabled. Always has been. How else could you amass that many tabs?
