so, so, works a bit, after some reopening saved sessions, the tabs are mangled more and more...

Sessions backup fine ... but on the restore, everything is out of order, which is problematic based on my usage patterns. Pre-v57 add-ons restored everything in the same order they were backup.

Can this be added? Thanks!

I'd rate the experience of using this addon as very bad.

First of all, I did not experience any losses of stored sessions, saving them, as well timed autosave, which is one of the most important features, do work.

However, the process of restoring a session is beyond horrible - every single tab is getting loaded into memory.

When trying to restore a session with this addon, Firefox ate around 12GB RAM, basically all available RAM I had (it would have probably ate all 32GB if I had them), and made PC completely unusable, it lagged to hell. I waited for around 20 minutes, but nothing improved, so I just gave up, and closed the browser (it crashed on close too).
After that I was able to use native browser session load, without problems, with all tabs not loaded into memory, like it should be.

I tried using "Load on Select" before, but it has problems with some of the sites - they do not load with this addon.

Great addon for saving tabs for later.
Also, using bookmarks as a session storage is a good decision.
You can use any bookmark addon to work with sessions for e.g. syncing between different computers and so on.

Unfortunately "Crash recovery" does not working as expected.
After I close and open browser most of my tabs in last session (from "crash recovery") is lost because URLs contains some garbage (tab title or something). It happens to me in 50% situations.
FF 56.0.2.

It is open source and it is the best. Thank you very much.

Nope. Not there yet...

Settings window is a mess, with all but the first check icons at the right margin of the previous line instead of before the tab title (text overflow because the text doesn't quite fit?).
Opening pinned tabs in the same window opens them all in full (not pinned).
Opening them in a new window moves the first one to the last position and opens it not pinned.

Needs work to be of any use to me.

Three starts for effort.

Я так понимаю, открытие всех вкладок по одной — не-баг-а-фича новой лисы, судя по тому, что так делают все «заменители» старого Session Manager? В любом случае, этот пока — лучший.

a lot better than the more popular options.
You can select what window to save or individual tabs from different windows.

interface isn't very slick but it does the job.

If I understand it correctly, the panels in MySessions that I save or are autosaved - they are saved in the form of bookmarks. That means that Firefox shows me that every panel I have open has been bookmarked and I dont know if I did that and saved the link into an appropriate folder or if that is just from the MySessions addon. Is it possible to do something about it? Something like hide the MySessions bookmarks from the Firefox? Thanks

Здравствуйте!
Я правильно понял, что положение табов в сохраненных сессиях не сохраняется? Или это у меня только так? Хотелось бы, чтобы сохраненные табы при перезапуске FF восстанавливались в том же порядке, в каком они были на момент сохранения сессии. А то я рассортировал их как мне надо, завершил FF, запустил заново - все вкладки перемешаны...

I'm still hoping for a function that auto-saved my personal saved Session.

I really like this session manager, but what I am sad about is that it insists to open a new WINDOW and not just open the "saved session" into the EXISTING WINDOW, and populate the tabs from there.

At least if there could be a setting, that asks....do you want to "Open a new Window", that could be unticked. It seems to me this could be just perfect if we had that choice. Many thanks though, and please introduce that setting if you can? I'd love to make my 4* review a 5* review!

For those who can't use MySessions because of its cookie dependency, I've just tested Tab Session Manager and it doesn't have that deficiency and is more full featured. I know the MySessions developer is claiming there is no cookie dependency, but for me it's a simple matter of enabling cookies to make MySession work and disabling them to immediately kill all of its functionality. One way or another, that's a dependency, so I've had to move to TSM.

How would i go about exporting sessions from this? Is there a folder somewhere where i can make a copy?

Здравствуйте, скажите пожалуйста куда сохраняются сессии и можно ли поменять эту папку на другую. Заранее спасибо.

This has been great so far. Does exactly what it said it will do. Looking forward to seeing the new features the developer is working on.

For all the negative reviewers, please read the description carefully, and understand that not all features can be imported into extensions. Stop punishing the developers of new add-ons trying to make things work in FF57 for things out of their control, its counter-productive.

Nice AddOn.
There is not much of that kind working with FF57 yet.

However, one thing does not work. When I change the options the changes only stay until I reboot FF. After reboot all is set back to the basic settings.
Have no idea why. May be this is saved as a cookie??

How can I import from SessionManager?

See my PPS at the bottom of this please!

On the right way, but miles to go yet.

First, the author deserves kudos for investing his/her time to create a replacement for that long term friend of all of us who come here to devour the passing away of the classical session manager.

Importing old sessions is the most important and prominent function these days immediately after the release of FF57.

The makers at Firefox / mozilla may have underestimated the part that independant addon-creators have played over the years for the users - and the appreciation that users spent for those little marvels that made the base structure so popular.

Now, MySessions seems to have some labours to fight with yet. It is much better that the new Session Manager that made my i7, equipped with 12 GB of RAM, stall when trying to reconstruct a 6 window / 960 tabs session. It seems to try that all in RAM , the first time I saw a RAM usage of 96% on that machine - with an endless usage of virtual memory, blocking any normal use of the machine.

Now, MySessions seems to do better. But it also seems to try and load every single content of any tab - that should be optionally deselectable! In my case, about 80 YouTube videos all started to play, with the previously set AutoPlay also disregarded (not sure if MySessions is responsible for that). Plus old tabs that triggered some downloads reappeared too (all contained in the sessions, but if they would not have been re-loaded, they would have rested in peace there... Bad habit on my side, ok, but...

Opening the reconstructed sessions in new windows makes sense, but be sure to know what was your previously opened set of windows...

I offer and volunteer to act as a beta tester for future versions, as a heavy-duty user who always finds something... :)

So the two vacant stars offer space for perfection. Your turn!

P.S.: After posting this, I read the previous exchange between you and other users here. I understand that the question of having all tabs open is a known issue and subject to more work and a possible solution.

Would it be possible to freeze them all to hibernization piece by piece immediately at the time of loading them? Maybe optionally selectable in an options switch array? Who ever booted a DEC PDP11 or an MITS Altair 8800 or an IMSAI 8080, for that matter, some 35 years ago, loves those switches... ;)

PPS: Sitting at the machine with the previously 6 windows / 980 tabs in the continuous session. I can't find the previous sessions. I looked in C:\Users\\AppData\Roaming\Mozilla\Firefox\Profiles\phzsk6df.default\sessionstore-backups, there are a few files but none is called something like sessionsomething.

Before I found MySessions, I tried the other suggested replacement and had to stop that after several hours (!!!!) of activities by using task manager.
Can it be that "the other one" deleted all old session files? I had set the queue to a pretty large number, and there had always been long lists of previously saved session sets.
I understand this is not a help forum - where to turn best with such questions? Thanks!

Since there is no way to reply to a reply here, I try this way: (2017-Nov20, 01 p.m., CET)

The addon you suggested - thanks for that - has not got the most benevolent comments and was updated last time 2 months ago. What benefit should that have? Specially for tabs, that are completely reloaded, like a first load, during the reconstruction of the old lists? Wouldn't they get into the hibernation state only on the second start of the session they are contained in?
