Great addon! has a lot of great features. Just how did you manage to remove the dropdown menu that normaly apears at the top of any sidebar in your screenshot?

I couldn't believe there was such a good extension for firefox! Wow!

Just finished up disabling the big clunky heap of TreeStyleTabs extensions and other tab addons to give this a shot. I am already deeply impressed and I've barely scratched the surface going through all the config & customization and behavior options all at your figertips in one place with Sidebery. Outstanding work!

*EDIT*
It seems shortly after I posted this review was the last time the github was updated. It's sitting with about 200 issues reported and only a single PR. C'mon, dev people, this is so damn good for FF--it kept me from being forced to a Chromium-based browser for almost a year now. Unfortunately I'm a network admin with no coding languages under my belt, but I just donated with a little note of thanks. It'd be tragic for this extension to fizzle out while it's just picking up more attention finally.

Amazing!

Thanks for the change in permissions. I really like this add-on, so well made, great work! ...for me the only thing missing is ability to rename a tab.

Something has been missing from Firefox for a long time from a usability perspective. Treestyle tabs tried to fill that gap, and did a great job - but, Sidebery is next level. An absolute must have for someone who lives in their web browser with 100s of tabs open in different contexts. Absolutely magical addon.

Add the Container Capability! ! MORE!

I'm so impressed by this add-on that I had to share some praise.
This is by far the best tab manager/ bookmark manager I've ever used on Firefox or any other browser.
It functions like One Tab, Group Speed Dial, and a bookmark manager all in one.
Everything is intuitive and every icon does what you think it will do. The pinned tabs are horizontally laid out above the vertical list of the all of the unpinned tabs. You can create a group from those tabs and nest the pages. You can expand and expand the groups of tabs and create a new group. Everything has quick access. You can drag and drop just about anything. It's my pick for the Best Productivity Add-On of the Decade. And that's coming from a real add-on junkie. Thanks devs and or devettes!
