There is a real need for a polished solution for session management in Firefox Quantum. This is the best equivalent I've found to Chrome Extensions like "Session Buddy".
Highly recommend for saving your Tab Sessions.

Works well, as described.

cool

Faster

Extensible very convenient, but it would be even better if the pinned tabs were restored identically (pinned, with mute sound, etc.). I would have liked also the possibility to rename saved sessions by a name more explicit than the date and time of creation. Otherwise good job, hoping to see one day my suggestions to the works.

A nice app that saves sessions and works perfectly. Saves sessions instantly with no problems. Restores the entire session or individual tabs.

Works as advertised, looks good visually, and long overdue.

I LOVE THIS APPS

The idea to save sessions with bookmarks is revolutionary and much needed! I would love to see this working on Firefox for Android. Please consider it! There is currently no way to save and transfer sessions on mobile, other than manually bookmarking and deleting every page.

The only other thing I could ask for is the ability to use this add-on, or an add-on like this, as a tab management tool, much like the chrome add-on "tabs outliner", which can unload currently opened tabs from ram while keeping those tabs attached in the same place to the same window. Please consider this as well, thanks!

Accidentally reported this add-on for abuse... so sorry about that. But anyway...
Thanks for making this extension! It's got great UI (especially the colourful buttons) and is filled with features and customizations, and best of all: no more importing/exporting for saved sessions; very ingenious of you to make use of Firefox's Sync feature!

I would really appreciate it if you could add drag-and-drop support (for manually reordering sessions/tabs from a specific session) in addition to the multi-selection support (which would be awesome if you want to save/open/delete individual tabs/sessions) that others have requested in their reviews!
Also, I was wondering if you would be adding support for Firefox on mobile (and maybe even Chrome) anywhere in the future. I currently use TabCloud on Chrome, which I wished the developer would add support for Firefox Quantum, so it would be really nice if this add-on had cross-browser support. If not, even if it's just support for Firefox on mobile, it would be great!
And also, it may just be me, but I find it a bit ugly how the text can appear under the star and x buttons in the search bar, but maybe that's just me.

Edit: Thanks for the quick and detailed reply.
Feel free to take your time adding the features; the extension is already amazing as it is right now. I'm not a very experienced dev yet, so I wouldn't know if how difficult adding support for Chrome is, but either way, I really do appreciate how you're doing all this for the community.
And I see your point... it's a lot of work to code a completely separate UI just for the mobile platform. Considering how big the PC version one was, it'll definitely be difficult to fit everything onto such a small screen. Thank you for mentioning it, though, and for the suggestion. It's not very ideal, but at least it's also not terribly difficult to access the sessions, but it is still quite annoying to have to open each tab individually.
I see, I'm glad I pointed it out then. I actually do give my sessions really descriptive names sometimes, so maybe you're right about how you might have missed it.

Anyway, it should be me who's thanking you for taking your time to reply, and for your dedication. I'm looking forward to any and all the future updates and features, and I wish you good luck on your journey!... Oh, and also, congrats on being one of the three winners for the extensions challenge!

Great ! and what is IMPORTANT for Me is fully sync via Firefox Account !

I need that session names will come from active Tab !

Then it will be Perfect and The Best.

I have 1 issue; auto-save doesn't appear to work for me. I have it enabled, set to every 300 seconds, but it's not saving any sessions for me. That aside, this addon still worth 5 stars, as every other addon (except the "old" Session Manager") has had real issues. I just manually save every so often now. I like how it uses bookmarks, because they're saved/synching already.

UPDATE: Hi, thanks for the quick response. The issue is a non-issue; I wrongly assumed the sessions were saved in the "Sessions" tab, but I think if I'm right, and from from reading your explanation, that's only the manually saved sessions. The auto-saved session is under the History tab. I think that's what confused me :) I see it now anyway; I just closed FF and then opened and then went to History, and the last session was there (i.e. the previousl current session). I think I was thinking it worked like other similar addons. Excellent addon, tyvm.

Simple, Elegant

Perfect tool ! Very easy and beautiful gui .
Hope Mozilla will integrate it to Firefox soon !
Thank you very much mr. Gabriel!

I think UX is pretty important when it comes to a session manager. Really like this add-on's style. Sync functionality is great. Developer seems responsive. Hopefully this add-on will continue to be updated :)

1) restoring in new window doesnt work for me
2) it would be perfect if the addon remembered the tree structure of addon: https://addons.mozilla.org/en-US/firefox/addon/tree-style-tab/

I just wanted an extension to save and restore the session to save time all days when I start my computer. This extension fulfills my expectations. Thanks.

Best bookmark/session/tab management add-ons till date.
But still need some improvements and options.
1. Option to show Small preview of saved tabs
2. Multiple selection of saved tabs to restore instead of all.
