Saved session with many tabs, then later went to retrieve and nothing was available, received bs message AFTER the fact, 'IndexedDB is not available in your browser'. Hunk of junk, poorly executed.

It was great for a while, but since last year it stopped working. What a shame.

After turning on the (BETA) cloud sync, FF could not start - crashes every time.
When I started FF in safe mode and disabled the Add-on, FF started normally.

расширение перестало открывать сохранённые сеансы.

это расширение перестало открывать сохранённые через экспорт файлы сеансов также.

всё пропало, всё что непосильным трудом создавалось, всё рухнуло.
ничего открыть невозможно, бесполезное вредное расширение
Tab Session Manager.

Too bad that the sole activity from the author in nearly a year is to update bakers.md. Not a single reply to the issues, and some of them are blocking issues, no commit on github whatsover.

all my saved, named and taged sessions have dissapeared! This program is usless unless I can easily recover what is lost.

It was a good extension, now wtf has it become. HOW THE HELL DO I SAVE SESSIONS

La sauvegarde automatique ne fonctionne pas, les sauvegardes manuelles disparaissent, seule la dernière est visible, et disparait après réouverture de Firefox. Rien ne s'enregistre dans le dossier "TabSessionManager - Backup".
Dommage, l'ihm est propre et le principe de fonctionnement est bon.

The functions of this addon are great, but what does not work at all is that the addon uses the entire memory.
and that is unacceptable!

When reinstalling, all sessions, despite the synchronization, are deleted. Thank you

Przestało działać, nie można przywracać całych okien, tylko pojedyncze karty!

Import doesn't work

Not a good tool if the sessions can't be downloaded - and not downloaded in .json but downloaded in CSV or HTML.

Deleted my session to spam save stupid autosaves when the session I had saved was saved manually, lost all my tabs forever, ridiculous do not recommend.

Deletes saved session without warning.

Doesn't show any currently open tabs.

More then half the functionality of this add-on doesn't work. Exporting a session doesn't work, saving more then one session at a time doesn't work (it just auto-deletes anything other then the most recently manually saved session), restoring sessions after a FF update doesn't work.


Overall avoid and report as much as possible. Add-on could be harmful at this point.

doesnt work automatically session saving!

I had over 75 GB of backup files in the downloads folder because I mistakenly turned off Reminder. You see, I have to manually delete old backups, even though a session manager should manage it, and it is possible through WebExtension API which Allow unlimited storage. I am sorry to say but I am disabling it, until a better solution is available :(

It's a mess. When you restore session, it DOES NOT restore the session, but ADDS windows and tabs to the currently open ones.

Suppose you have 10 windows and saved the session. Then later on you navigated to some other URLs. Now you want to restore the saved session. But after you click on restore, current windows will NOT be closed, but new windows will be added. Now instead of 10 windows you have 20. If you activated autosave and restore a newer version later on, you will have 40 windows, then 80, then 160, etc. Each windows will be duplicated 4, 8, 16 times etc.

I don't see any option to disable this awkward mode.

Having this awkward mode makes the extension unusable.
