It does its job.THANK YOU!

Good job, It works very really well.Thank you!!

Right at the time I was looking for a replacement for OneTab this beauty appears. Thank you very much.

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.

request: ability to import Session Manager's data, please ;)

bug: i have turned off "save session when window close", but after restart, there is still a "auto saved - windows was closed" session.

1.3.2, firefox 56.

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.

As a very happy long-term Session Manager user, I salute your efforts here! Simple and effective. This should help with our Session Manager withdrawal symptoms.

A few thoughts for further refinement:
1) Logo barely visible on gray ribbon. A multi-color icon would help visibility for diverse color needs. Look too at Firefox's closed window/tab icon; white but outlined in black, thus visible on any background really
2) A third save scheme (daily) would be useful, perhaps at first use each day, i.e. 12:01am or whenever Firefox is next open
3) The list of saved sessions might be easier to digest as single line entries; you might need to abbreviate some data, such as save type (Regular (or Interval), Daily, Closed, and User)

Thanks for launching this!

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.

A minimal session manager which does exactly what it advertises. A lifesaver when the Firefox built-in session restore forgets a window or three.

The two (Edit: now only one!) small downsides in my opinion are a) the mentioned missing autosave on exit, or autosaving every 30s but only keeping the newest one, and b) that upon session restore it reloads all tabs - unlike the built-in session restore which loads tabs as inactive or unloaded.

Great Add-on it should be a default option

I wish I had thought of using something like this years ago. Works great on the latest Beta of FF

Finally working session manager on FF57+, THANK YOU!

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.

Very good!

thank you so much
