An essential plugin. Rated 5 out of 5 stars

If one juggles with too many tabs (using Tab groups) this plugin is a must.

Works perfectly well - Fx42 Rated 5 out of 5 stars

Don't pay attention to s.c. 'reviews' by Biscuit1001 (who couldn't even find the toolbar buttons or menu items). By vvb Rrraven (who wrote:
"... The storage format looks like it was designed by drunken monkeys ..." - well, the format is written by mozilla kids, why complain here? To understand what you're talking about, should have clicked the links provided by developer and read about this extension). And, of course, by testcore (who - it looks like - posted garbage in a run by spite or just like the other two can't find his way out of a paper bag).

This is an excellent extension, very well supported through a dozen of years by now, loaded with options and works well.

To you, 'writers' i'd suggest learn to read before you write. Just above this review textbox, there's a site suggestion for a review which says among other things:
"Please do not post bug reports in reviews" . And the extension developer provided a link to the documentation (which is as complete as it can possibly be) and the thread where you can post any question you might have and/or report bugs (which usually are promptly fixed, BTW).

One of the best extensions out there, a must have i install first thing in every profile for years. Very highly recommend, nobody should browse without it!

Terribly useful, but doesn't work with Pale Moon Rated 4 out of 5 stars

The session-saving-and-loading-thingy functionality in this add-on is incredibly useful, and as someone who's very prone to starting large, long multi-window research sessions at the drop of a hat, I've come to rely on it as a natural part of how I do browsing, because otherwise I wouldn't be able to close my browser until I finished, which can be disruptive to other computer-type-things I might want (or have) to do.

However, (and this isn't Mr. Kraft's fault but it's still a big however), I recently had to switch to Pale Moon due to Mozilla's continued flagrant disregard for user friendliness, customizability, good design and common sense, and sadly, this add-on is not compatible with Pale Moon, nor is there a compatible version. I would really appreciate having something like that made, if it's not too much trouble or anything.

Doesn't work in latest nightly Rated 5 out of 5 stars

What happened? It was working fine for awhile, then I updated Firefox to 43 Beta 6, then went back to use latest nightly, and now it stopped working. It doesn't even show up in the tools menu anymore, and the icon on the toolbar is faded out. I tried the latest developmental version, and it still doesn't work. Any way to fix it? I fixed it by updating to the developmental version, but the weird thing is, that I did that the first time, and it still wasn't working. It wasn't until I did it a second time that it started working. Strange, but at least it's working now.

Session Manager Toolbar icon missing Rated 1 out of 5 stars

Session Manager Toolbar icon is nowhere to be found. In customize only the "Undo Close" icon available. No options available from the Tools menu. Seems to save the session - when I kill FF process and start FF again it pops up a list of sessions but it fails to restore the chosen one

A must-have ! Rated 5 out of 5 stars

I heard that Mozilla will remove the Tab Groups funtion soon, but my daily work highly rely on it.

So I begin to find some other tools to replace it.
I use this with Tree Style Tab and Rename Tab Title, so that I can organize Tab Groups, rename group names and close Firefox without losing the renamed group name by loading the last session.

Hope these wonderful add-ons won't be affected by Firefox updates.

Feature Suggestions Rated 5 out of 5 stars

Thanks for the great add-on! Some useful functions are still missing. Pls consider adding:
1. "Append to Session" option to allow amending currently open session or window to a previously saved session without re-opening it, and with sorting out duplicates
2. Allow at least 2-3 level Group Hierarchy to properly group multiple sessions to subgroups. Or allow users to create new folders in Session Folder via Windows Explorer, and sort existing saved sessions into them, while still accessible in SM
3. Allow Import Session from Chrome Session Buddy (https://chrome.google.com/webstore/detail/session-buddy/edacconmaakjimmfgnblocblbcdcpbko?hl=en), and Export Session in a format, compatible with it, for using saved sessions in both browsers interchangeably.

Yes, it restores your sessions! Rated 5 out of 5 stars

This plug-in helped me restore my session after Firefox had not restored my tabs. Thank you.

Really good! Rated 4 out of 5 stars

Useful, it would be better if the "append to session" button didn't open a new window every time. I got 20 windows in a session, quite difficult and time-consuming to merge!

Questions Rated 4 out of 5 stars

What I want is every session I end, I want all the windows to be saved unless I manually delete it. How do I ensure that? (your users guide is a bit complex).

For example if I load an old session, then decide I want to load another session instead and click Replace current session, will that delete the session in the archive or just the windows iI have open now?

Also, you say you can back up saved sessions but don't explain how (for non techy like me). Just copy and paste the folder into documents?

Genial ! Rated 5 out of 5 stars

After installing this addon I restored all my tabs with two clicks.
Thank you !

The button for Session Manager has disappeared Rated 3 out of 5 stars

I like this add-on. It's very useful.
But the button for Session Manager has disappeared from the toolbar. And it isn't in the list of buttons when I click "Customize".
Version of Firefox is 41.0.2.

This should be a permanent part of Firefox! Rated 5 out of 5 stars

If I was stuck on a desert island and could only take one add-on with me, this would be it!

FF is my favorite browser, but each one has its warts. FF crashes from time to time. That's a simple fact. But Session Manager makes the "unbearable" merely "inconvenient". Session Manager remembers everything, every time, and for as long as you want it to. It gives you security and peace of mind. And COMPLETE control. The author has thought of everything. But if anything is missing in Session Manager, then its probably in Tabmix Plus, which is an add-on marriage made in heaven.

When the Firefox crash recovery feature "grew up", Session Manager is what resulted.

Having Session Manager in your add-ons means never having to say you're sorry!

Install it. Now.

(P.S. I don't write reviews. Mosaic was my first browser, and I've used every one between then and now. But this is the FIRST time I have ever written a review for a browser, add-on or anything of the like. I really, really do love Session Manager, or I wouldn't be "here")

One can never have enough backups. When it comes to browser sessions, this extension does just that: session backups. And it does it perfectly - I never lost a tab or session since I started using it.
