★☆☆☆☆ Outfrost · 17 Oct 2026 · v7.4.0This extension is abandonware, it has pages and pages of data loss issue reports dating back years, with zero interest from the maintainer, who only comes in every few months to upload new translations and update the list of financial supporters. For me personally, it worked for a while, until it consumed 4 GB(!) of disk space, plus 2.2 GB for json backups, and stopped working. Even after deleting the old data, it just won't autosave any sessions, which was the whole point of its existence.

★★★★★ Firefox user 18484444 · 17 Oct 2026 · v7.4.0Just saved my ass. It's ridiculous that if you experience certain crashes in Firefox you can lose your entire session. I'm glad I downloaded this extension many years ago just in case because otherwise I would have lost 49 tabs today.

★★★★★ mlwl · 5 Oct 2026 · v7.4.0I love this Add-On, it saves every single window with one single click, the UI is clear and easy. My Mac Mini was in sleep mode tonight and when we had a power outage tonight, Tab Session Manager saved me and I could restore my complete session this morning

★★★★★ Charles Shank · 29 Sep 2026 · v7.4.0I have tried several other auto-tab openings extensions. This is by far the best and very powerful. The only thing I wish it did was allow you to drag and drop the order of how the tabs open. Regardless, it is a very professionally done extension. Thank you.

★★★★★ firaweti · 1 Sep 2026 · v7.4.0Très pratique pour sauvegarder ses groupes d'onglets et reprendre une activité précise liée à ceux-ci. Il y a beaucoup d'options de sauvegarde pour choisir comment on utilise l'extension !

★☆☆☆☆ Firefox user 17633691 · 19 Jul 2026 · v7.4.0Garbage extension. Can not find specific previous session. UI absolutely terrible. I can not emphasize how much I hate this PoS software. Uninstalling.
