yesterday i had a closer look to TSM and got a clue how it works and what features.

i also had tab-saver installed and dismissed it now.

but what i miss is an import export feature like tab-saver. maybe not for separate sessions but for all sessions would be nice.

another point to mention is the UI design - i would prefer it more clear, eg:

1 Window, 1 Tab | Open | Delete
(2017-10-19 11-12-13)
Window1
(fav)(tab)

i had a closer look into and that is possible when positioning the div elements in another formation. ofc the css need a polish to fit again.

translating may be more complicated because many strings are hard coded and some are only notify(e.message);

PS @Jacob - running perfect on b9 and now b10 - new window all stored tabs. try a new profile

4* because import/export ;)

a proudfull replacement for legacy "session manager" - wonderful job.

Works really well, but adding an option to automatically restore a session when booting up firefox would be great. I like to keep outlook and slack as pinned tabs that start up with firefox, but get rid of every other tab when I close firefox.

This extension is really nice! Thanks for making it happen! I'm on FF 57 beta right now and session management is pretty messed up. Without this extension I will lose my tabs every time I restart FF.

I found one problem: this extension would save and reopen private windows as well, which defeats the purpose of a private window. I hope there's a way to filter them out of the save, or at least out of the autosave.

A feature request: Is it possible to add a "remove all" button? Remove them one by one can be a pain at times.

Works wonderfully in automatic mode with a configurable interval to suit your needs. Supports container state as of ver1.3.2.

Tiniest thing keeping me from 5-staring: Open and Remove are too close together & Remove has no confirmation.

Other than that little thing, I'm as happy as I can be.
