WARNING: If you use large numbers of tabs this add-on will frequently destroy the organisational structure of the tabs you have sorted into different panels when closing and reopening a browser session, requiring you to potentially reorganise large numbers of tabs or close the affected browser windows and attempt to load a saved snapshot of them, wasting a lot of your time.

As other reviewers have already mentioned, this problem doesn't appear to be an issue if you only use small numbers of tabs.

I tried this add-on after being a long time 'Tree Tabs' user (which handles large numbers of tabs reliably) and was hoping Sidebery would be a potential replacement with more QoL features.

Unfortunately Sidebery's inability to reliably save and restore browser session tab structures with large numbers of tabs means I would not recommend this to anyone who browses with large numbers of tabs.

Hopefully this issue can be fixed as Sidebery has a lot of good things going in its favour (e.g. clean UI, snapshot save system, panel sorting, containers) however until this critical issue is fixed the user experience is frustrating and wastes their time.

It's great when it comes to keeping tabs neatly arranged on a smaller scale, however, it doesn't manage large numbers of tabs (500+) and containers (8) well, especially when combined with multiple windows. With multiple windows the containers become routinely reset (all tabs are moved to the default container) and the add-on confuses placement of some tabs. Pinned tabs become routinely unpinned and I have also lost the configuration of containers several times now, which is a shame because I loved using the simple automation and integration with firefox containers this add-on offers. It is in my opinion a perfect tabs manager when it comes to the features, hovewer the performance is lacking.

Non è male ma non fa nulla più che aggiungere una spalla con elementi vari.

Это прекрасное дополнение, которым всегда пользуюсь. Но есть одна существенная проблема. После закрытия браузера слетает группировка вкладок, что очень разочаровывает. Надеюсь, проблему исправят.
