Straight forward and clean interface. Works properly for me. I see other folks have said it's not working properly for them - but it is working properly for me. Perhaps the developer fixed some issues? (p.s. I am not affiliated with the developer in any way)

I hope this extension lets users choose which session to restore. I am instaLLing it because of the pop-up windows which get closed at the end of the session and then i cannot see any of the previously open tabs.
PS. Today I had 7 useful tabs in Firefox, and then I closed the main window. After that I found another window with some site which opened in the background. After closing that separate window, all my 7 useful tabs were wasted.
I would like to avoid losing tabs in this way in the future, and that is why I am installing your extension.
Also, I hope it has autosaving, because I will not save sessions. I just forget about it when I read all those 7 tabs.

Your extension has a problem when restoring sessions since the restored Tabs are not kept in the same position and order as they where before on the Tab Bar but they are all scrambled to new positions creating a chaos of missaligned Tabs. This flaw needs to be fixed asap.

1.9.0 with 57.0.4
cannot automatically restore last save at the startup
but 1.8.0 is ok

Recent updates were simply great.
Tab Session behaves very well and can restore my sessions (-+150 tabs) using the "lazy" function without any crashing.

Thank you for this app, it saved my bacon twice today. Once when I thought I had lost ALL 45 open tabs in FF, when FF did yet ANOTHER release that screwed up my tabs, and then when I tried using another tab app, it misbehaved badly, totally corrupting them and I had to remove it.

Turned out, both times when I clicked on the little icon, and then clicked restore, the files were there and I was able to get an uncorrupted file to save and reload my tabs.

Only problem I've had with it is that for some reason, I can no longer use the "import" function as when I do "browse", I get taken to a subfolder that has my back up under "Weather.com" and it's only my weather app files that are there. I can NOT find my session.js folder anywhere on my computer. Don't know where or when it left the building. That could be my fault, the fault of another update of the (crappy) "new, Improved" FF browser that has done nothing but crash.

It also saved my tabs from the massive crash when the initial update left my tabs gone for good - or so I thought. I was able to save about 110 tabs with this app.

Thank you for the time and effort you put into making this app.

Working well for me and the developer is very responsive.

Simple and powerful interface.
Does exactly what I want it to do which is saving groups of tabs so that I can open them all later.

Unsure why the ratings are so low, possibly an older, more alpha version.

this add-on's auto-save has saved me numerous times. Firefox multi-windows with pinned tabs is great, but closing the wrong window (pinned tabs) will get lost. However this addon saves the day every time such mistake is made. 💚

Спасибо за дополнение, оно очень помогает! Но очень хотелось бы одну, очень важную, функцию добавить. Многие вкладки в сессии имеют несколько страниц в глубину, но после восстановления сессии остаются только те, что были на самом верху. Сделайте, пожалуйста, так, чтобы сохранялись в сессии не просто открытые вкладки, но и глубина (история) вкладок. Тогда полноценные пять звёзд вашему приложению будут обеспечены. Заранее спасибо! С Новым Годом!!!

Thanks for the addition, it really helps! But I would very much like to add one very important function. Many tabs in the session have several pages in depth, but after the session is recovered, only those that were at the top remain. Please make sure that not only open tabs are saved in the session, but also the depth (history) of the tabs. Then a full five stars to your application will be provided. Thank you in advance! Happy New Year!!!

Perfect!

while normally it does its job, in my case it failed spectacularly when i needed it most. i had a power failure, and upon boot i find all of my tabs are wiped as usual thanks to firefox's abysmal handling of sessions. so i go to tab session manager to restore them, only to find that its extension database (alongside a few other extensions) was also wiped/corrupted, which means no tabs at all.

the extension could use some sort of cloud backup, on google drive or dropbox to store selected (or all) sessions online for quick retrieval in case firefox's unreliable database gets corrupted or wiped.

My comparison is based on my previous experience with discontinued "Session Manager". First, thank you for filling in the gap... I was spoiled by Session Manager. "Tab Session Manager" works as represented. It allows me to recover exactly my last session... Which is better than nothing... But if you forget to close a pop up, last session it recalls is that pop up alone. Session Manager allowed you to go back 5-10 back ups. It also allowed you to customize Sessions... For example, Personal vs Business vs Personal Finances vs Personal entertainment. Hopefully these feature will be added in future releases. To that end, I am making a contribution.
