one of the best TAB extensions. It saves me a lot of trouble having a lot of opened tabs.

Keeps the open tabs closed :-) Thus saving a lot of memory, and my browser starts much faster

used to be good - now can't get it to run in Firefox, whereas in Chrome is fine

好好的组件开发者！！！产品也同样好！

I used to love this, but I found out that once you share your tabs, those get indexed in Google, be careful.

After enabling `browser.tabs.groups.enabled`, the need for a separate extension disappeared.
