This add-on is really great. I have been using it for a couple of years, now. It is really user friendly and it is great for saving multiple tabs on a subject and going back to them later. I couldn't be without it now. Thank you CromS for your hard work!

Hi, MySession seems more robust than Tab Session Manager (TSM uses indexDB; it's json got corrupted so I lost alll my sessions), but maybe you could consider implement this TSM good things:
-'save session on close' option [without using 'save each __minutes', *even when eg the PC unespectedly shuts down from energy failure*, amazingly it usually manages to recover the tabs.]
-it restores tabs according to the Firefox 'Container' each tabs is when saving the session, eg I can have a session with all/some 'Work' or 'Personal' Containers. [Maybe this can't be done in MySession since regular Bookmarks (only for now until new API?) can't save the 'Container' status?]
-it opens the session starting on the tab you were when saved [not necessarily on the 1st tab] eg while being in the last tab (eg 9 tabs, you were in tab #9, opening session starts in tab #9, not in #1).
-if you click to expand the list of tabs of a session, > click on any tab > only that tab opens in the window you are.
Thanks.
Edit: I guess I was wrong about the last point, so 1+star (only used the addon 1 time because from the proposals, at least I cannot forego the containers function.)
The reason for 3 is (using lazy Loading) eg I don't want always to load tab#1, but [in the example, it could be tabb5 or whatever] start in/only load tab9, then i after i close it, Tab8 loads, and so on, until i stop and close the window, without loading the 1st tabs. Without the function, before opening the session i would have to put FFx on 'work offline' before tab1 loads , then put FF 'onlne', then click tab9 etc. (or arrange the tabs in different order before saving the session.)
Thx.

thank you. it's a must have in my case.
would give 5 stars but recent update introduced some bugs. 1. whenever I open the browser MySessions options tab opens automatically. 2. also every single link inside this tab opens another options tab.
I'm using FF 66.0.5 x64 and MySessions 2.13.4, Win7 SP1 x64.

edit: updating 2.13.5 fixed above problems. kudos to the Author for the immediate reaction. 5/5

Must Have!
Автор Гений!

Really good utility. Big Fan. Indispensable for someone who habitually has waaay too many tabs open (embarraassed to say how many...).

Used it for a couple of years and it's far better than nothing. It's saved me from a few bad crashes and assists in organizing tabs a bit. But for the last year I consistently find the UI is laggy, unresponsive, and sometimes impossible to use. I understand taking a while to load large tab lists, but quite often it fails to display all my sessions, button clicks don't register, and other basic errors. Otherwise, it's great, but it has become a frustrating experience to use.

Works like a charm, especially for when working on multiple research projects at a time. (TIP: You can open anything in a different tab with the middle mouse button. This works with any link/image. With MySession you can open a saved session in a new window)

Great addon! Is there a possibility to disable the automatically bookmarking? Thanks!

Отличное расширение! Единственное, которое позволило мне перейти на более новую версию браузера не потеряв все полезные сайты, которые я собрала за последние пять лет. Все самые важные функции присутствуют и отлично работают. Лучшее расширение из всех доступных.
Если можно, я бы хотела попросить добавить возможность группировки сессий (у меня три с лишним сотни сессий, иногда я просто теряюсь) и возможность изменить название сохраняемой сессии по умолчанию на дату сохранения.
В любом случае, спасибо, что сделали это расширение.

Great extention! The only one that allowed me to transfer to the newer vertion of Firefox without losing five years of history and useful sites. Has all the most important functions and works great. Out of all avalible extentions this is the best one.
If I may ask, could you please add the ability to put sessions in groups (I have more than three hundred sessions, I get lost in then sometimes) and option to change the default session name to the date of the saving.
Anyway, thank you for making this extention.

Отличное дополнение - лучшее в своем роде!
Добавь ссылки на донат через яндекс, станешь получать гораздо больше лойсов!

The only issue I have is that sometimes it doesn't save them all. Let's say I saved 200 tabs, on the right panel it shows "name (200 tabs)", but on the left only 170 are shown.
So now I do like 3 saves each time just in case. It'd be cool if you could add an option to mix saves and ignore repeated urls.

Credo che questa, sia, attualmente, la migliore estensione per le sessioni. La piu' completa e, sopratutto, funzionante in tutte le sue opzioni. Complimenti allo sviluppatore!

I think this is currently the best extension for session management. The most complete and, above all, working in all its functions. Congratulations to the developer!
