It's literally perfect

Works well, until it doesnt

Then you'll lose any tab you had open and have no way find out what they where apparently

works perfectly and so customizable so fits my very specific workflow :)

Unlike TST; Handles tab groups and tab colour. Panels adds another level of organization.

Lost a star for: 1) Not providing for increased indent on child tabs (group tab colour, inherited by child tabs serves the same visual purpose; which doesn't apply when you are actively accessing children of multiple search tabs) [settings, style editor, tabs, indent=25,on]. 2) The inability to show bookmarks at the same time ala TST. (but there is an icon {bottom middle} to bring up a book mark sub-panel).

There is no obvious way to show bookmarks in the sidebar. I searched for about 10 minutes and could not find an option to show the bookmarks. All I got in the sidebar was tabs—which I definitely did not want to show in my sidebar. Moreover, even it I were able to located the setting to install my bookmarks in the sidebar, I do not believe I would be able to with one click open a sidebar with my bookmarks showing. Apparently I would have had to click on the Firefox sidebar icon, then to click on the Sidebery icon. That's not acceptable. Is it unreasonable to be able to make one click to show a sidebar of bookmarks?

I've been using this for a few days and it's been exactly what I needed so far. I'm one of those people who opens way too many tabs when researching things, figuring I'll do the slower sorting and bookmarking later when I'm pressed for time. Sidebery lets me manage any number of tabs better than most of the add-ons I've tried. Give it some time to really adjust to the change. Loads of configurable options to allow me to fit it pretty much perfectly to my use profile. It appears to also be managing memory better than just overloading the regular tab bar but I'll need to track that longer term.

Amazing addon. Was using tree style tabs but for that I needed like 10 addons to get most of the features I wanted. With sidebery it come with everything plus a bunch of stuff I didn't even know I wanted. The panels are a game changer.

As a user of the Sidebery extension for Zen Browser, I had high expectations for improving my tab management experience. I wanted Sidebery to automatically group tabs from the same domain into one tab, which would reduce clutter and simplify navigation between related pages. Additionally, I hoped for an option to display only the logos of the domains rather than the full text. This minimalist approach would create a cleaner look and allow for quick access to tabs by clicking on the logo. However, despite its goals of sorting and organization, the application still tends to clutter my screen and occupy too much space. Overall, I was looking for a tool that enhances both functionality and visual appeal, but I found it lacking in these areas.

Brilliant. Had been using Tree Style Tab for the last few years but that took a lot of configuring (and re-configuring) and I recently noticed it was significantly impacting start-up time. Had been waiting (for ages!) for vertical tabs to be supported natively, but was very disappointed with Firefox 136.

Decided to give Sidebery a go and I'm impressed. Minimal customisation required to get it looking/behaving how I want, and it has significantly speeded things up.

Thank you!

Amazing extension with a lot of options and customization! Has everything I've been looking for. Take some time to get to know the extension before leaving a 1 star review.
