Works as advertised, except it does not restore window size and location across multiple monitors.

great add-on, but please add other sync options! currently only google is supported which collects personal data :(

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

This add-on is the FIRST one I add on to every new installation of Firefox. This is a MUST HAVE. It has pulled my fat out of the fire.

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

несовместимо с версиями от 106+.. непонимаю зачем здесь тогда. лажит. и иконка не отображается

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.

:\ having trouble closing tabs from within TSM because the scroll bar on the right covers the X buttons

could you please move the X's to the left of the tab names or make the scroll bar smaller please? I am using most recent Firefox..

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
