Seems to work fine..and most importantly also seems to successfully import "Session Manager" extension session files

In my installation it saves and restores tabs in their original order, no problems there.

I have 3 Questions:
---------------------

1) Where are the TSM session files saved? (their folder location)
...the "storage.js" file in the extension's folder does not include any relevant information.

2) Will "Session Manager" session file compatibility be maintained in the future?

3) Can the TSM session be converted to "Session Manager" files?

I just recently spent a week trying to salvage my sessions (several hunded tabs a piece) from another extension in FF Quantum, which were lost after a crash following an extension update.
Recently I saw a similar issue happen with TSM...

..I am terrified of this happening again because my work (researcher) depends on keeping and organizing sessions of saved tabs...
so I will be maintaining both a Quantum and a Gecko installation with SM installed, just in case...

I need a sort of "insurance policy" to maintain "mental health" and prevent professional disasters...

...of course one thing I can do is use my Cyberfox/Waterfox installation to restore a TSM session and then re-save it in Session Manager...

Since you have obviously considered the issue of SM compatibility, if there is any info you can share on this, I would be grateful

better than the other adds, really similar than old unsuported sesion manager. Thanks for great add and your work!

I love this add-on, although I wish it would ask before restoring previous sessions on reopening a browser.

The missing session returned to its original state!!!
Thank You(^_^)b

This is GOOD stuff!

excellent

Was a 5 (will have to drop soon). With the 3.0.0 upgrade on 2018March20, on Firefox 58.0.? and then soon after on Firefox 59.0.1 (64-bit version) on Windows 7 Professional, the clicking on the Add-on icon in the toolbar, the saved session navigation tool would display but would be blank (I have a lot of saved session, so I pretty miffed for a little bit). I tried to save some new ones, to no avail.

That said! After futzing around with pretty printing the storage.js file appears to be intact, and the Add-on appears to be auto-saving the various tabs on the defined interval (15 minutes, I think).

I'd love to see a fix appear, because I really don't want to have to write a perl script to extract all of those backslash escaped URLs in the file (or do it by hand! :-O )

Thanks for a (usually) great tool.

Fait le job, interface claire et intuitive.

This is a great add on! Thanks!

Really really useful - after the old addon stopped working I was left without feature that is absolutely crucial for me as I always have billion tabs.

I would like restoring the content of text boxes too, similar to the "Show your windows and tabs from last time" Firefox setting.

I'm not sure why this has such a low rating. Sure, it isn't as good as Session Manager was in the old Firefox Add-Ons, but it's the best replacement there is and it's improving all the time.
