Review summary

Users consistently praise Sidebery for powerful tab grouping, nesting, and collapsing to reduce clutter. They also value memory savings from unloading tabs in collapsed groups, rich customization (colors by domain, indentation, placement), and automatic backups that preserve layouts. A recurring limitation is the desire for native multi-panel or multiple tab groups. Overall, Sidebery is viewed as a productivity booster and essential tab-management tool, with some feature gaps.

Pros

Excellent tab grouping and hierarchical organization with nesting and collapsible groups.
Memory-friendly design that unloads tabs in collapsed groups to reduce RAM usage.
Rich customization and visual cues, including color-by-domain coding, parent-child indentation, and flexible tab placement.
Automatic backups that preserve tab layouts and state.
Strong productivity boost and workflow improvement reported by many users.

Cons

Lack of native multi-panel/tab group support: a commonly requested feature to extend the current single-panel layout.

2026-06-23	pa*****	Really like this extension. I have just one request: please add the option to create a new tab + when hovering over a group (folder) we have created, while keeping it colour setting. I know it can be made by clicking on the group heading in the page that way, but my suggestion would be a nice bonus! thanks for this extension very much!

2026-06-10	Fi*****	This fixes so many little nitpicks and inconveniences I have in my daily use of Firefox! I usually have hundreds of Tabs open in sometimes more than 10 windows. Now I can have one window with multiple panels, each categorised and it is so simple to move multiple tabs between them. I love the vertical tabs that Firefox added natively, but they can not as easily be sorted and you cant even have the newest one appear on top. Now I can! Amazing add-on! I hope it keeps on going for a very long time <3
