This extension has got to the point that I no longer run Firefox ESR in order to use the old Session Manager. Sure, it still has some bugs and missing features but it is quite usable. If you have problems losing sessions try the Export menu item to make manual backups.
To all those who complain about this extension not being as full-featured and reliable as the old Session Manager, remember that sienori started from scratch with a Web extension API that was so unfriendly to session management that none of the old extensions were ported. I think he has achieved a lot and encourage him to continue improving Tab Session Manager. Thanks.

This add-on works perfectly for me. I use it every day. Thank you VERY much for adding the "save position" functionality. I missed this feature a lot. But now everything is just perfect.

Getting better and better with every update. Keep up the good work!

Simple but perfect. Nice work ;)

I love it because i don't have to remember what I was doing when I have to reboot or something, etc.

I'm not really rating this 4. I haven't started using it and just want to ask question:

The backup filelocation is stated as: "Specify the folder to save the backup file. The save location is limited to the folder under Firefox download folder."

I have no Firefox download folder. That is, my option in Firefox for download locations is "ALWAYS ASK". I would like to specify the location, but it looks like I can't. Does it still use the folder listed (but not CHECKED)?

It's getting better! Much more convenient with exporting session and importing sessions, as well as the NEW added to ability to edit a saved session and delete any tabs from the saved session! Keep up the good work!

This addon does exactly what I want. I could not ask for anything more. The settings are easy to understand and configure. It is an amazing addon for all users who juggle with different windows with tons of tabs open on each of them.

Last update give us a few very useful features like removing links or whole windows from session without need of load it, and easiest way to replace session. It made addon very convenient. Unfortunately I don't have paypal in my country so I can't donate to it =(

Finally, I can restore a session and have my tabs in the same position. I've been waiting a long time for this.

Thanks. :-)

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
