Stop working automatically for 1 month or so. Only manually saved sessions work. Some files are probably corrupted but it fail silently.

Good when it works but regularely stops working, its supposed to save every 15 minutes and when the browser is closed.

The newest save is more then 3 weeks old making this addon pretty much useless.

On some devices and browsers is Google login (sync) not working.

yes, at last firefox doesn't randomly delete all pinned tabs. thanks

Literally erased every single one of my sessions when updating. literally beyond useless

Имеется БАГ тянущийся еще с 2024-го года. Автор так его и не решил и не собирается решать. мда-уж

Worked great when first installed but the last sessions backup was March 2022. It's 2023 and I can't find my any history to restore - on PC. Is it hidden?

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.

Good for autosaving sessions but tracking does not work ok. When using startup session it stop being tracked and not updated, is just one more saved session

Suddenly one session saved for later and renamed changed its name

Uninstalling extension, is almost unusable

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

I forgot I had this installed and it just saved my butt. For whatever reason, a Firefox window would not open after closing and restarting my PC. Tried a lot of things to get them back but then remembered this add on. Needless to say, I got my lost window back.
