"Pinned tabs are not supported".

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

One of the good alternatives to Vivaldi's tab stack feature.

Excellent replacement for the old Panorama. The only... doubt is that last update was about a year ago. Is it still supported?

Really good for organizing tabs, but when you have many tabs stashed or organized it will be very VERY slow to show them when you go to settings. I had to remove the extension because of that.

This is by far the best tab manager I've ever used.

I'd request the ability to change the folder it records tabs in to whatever folder I designate: I don't want it in my bookmarks or in my downloads folder.


Also, another review claimed it didn't work on Linux. That is not true, at least on the couple of Linux machines I've used it on.

This extensions seems nice at first glance, but after using this extension for a while, I view it as being broken. When you open Firefox and you have a lot of tabs already open, you sometime get tab duplication. A lot of the tabs gets duplicated. It makes Firefox very slow to startup. It is unusable in Linux. When you open Firefox, the tabs load without any end. It loads forever and Firefox is unresponsive. So to summarize:

1) Tabs duplication bug
2) Very slow Firefox startup
3) Unusable in Linux, it simply does not work in Linux

I can't rate this extension more than 1.

Very nice for working with many projects.

Cumbersome to use. Not intuitive. I thought maybe I could take a few open tabs out of several and group them. Sure, but now the rest of the tabs are gone unless I also group them. Essentially if you want to group, you have to group everything into groups or you're accessing your non-grouped tabs through a little dropdown. If that's not the case, it wasn't intuitive enough to figure out otherwise or would be efficient to use.

A must have if you like to organise your stuff.
