Exactly what I was looking for; loads [.session] files.

Container support required

this is it

I love this extension. It works.

Sometimes it works, sometimes not. When its not working it can only opens one of the windows from the saved session.

能够保存浏览状态，特别好

it save to my bookmarks and bloats it up.

and saved sessions take forever to load.

effectively useless :(

Hi. thanks for your work in this extension, but i have a problem...

I cant make it to backup my sessions in the folder i choose, of course is inside the default folder, so how it work that option?

the only thing that work in the default folder is the "autosave" but also that cant be change to a subfolder.

subfolders doesn't work?

what is the correct way to write the directory path in the option?

"Save backup to file, save path"

also, the "download files and read....." is enabled.

thanks.

Solo restaura las pestañas que hayas usado el dia que se guarda la sesion. NO restaura las pestañas abiertas que no hayas usado

not perfect, but improving...most annoying bug, sometimes the option "select all" will only select the "current window"

after last firefox update...the restore function doesnt open all the saved windows just the first one.

I like Mysessions, thanks for all the work.
One thing I miss, please make it possible to define the places where the data is saved, I don't like the bookmark saving part, that bloats everything up and is not very useful or needed. I would like that the data is only saved to save folder local.

Thanks in Advance

I like the concept. Unfortunately, I found this add-on unresponsive to my settings; and when I had a crash that Firefox did not recover, this add-on did not help.

Edit: replying to the developer response: it appeared that nothing had been saved for the past several weeks. The add-on kept ignoring the folder that I designated for the backups; there aren't any recent backups in either my specified folder or in the folder that the add-on kept choosing. Possibly they are somewhere else. But I don't see them in Firefox Bookmarks either.

This is the best Session Manager. Sure, there are some bugs, but the alternatives have worse bugs, a clunkier user interface, and/or limited features. Ever since Michael Kraft's Session Manager from Firefox 56, I have regularly searched for a replacement. Again and again, MySessions has proven to be the best.

– for a session that should have had 16 (sixteen) tabs, only 8 (eight) existed.

– the preference to use a tab (not a pop-up) for the interface is not respected.

Inexcusably bad UI, as if the designer has never been exposed to technology after 2003

Unreliable. Several times from one day to the next the content of a saved sassion has changed with tabs missing

I love this session saver. It's the only reason I still use Firefox. My sessions are an archive of my life, let alone browser history. It has never failed me. Only one thing could improve it as far as I'm concerned and that would be a search feature. Sometimes I just remember a fragment, like "red froghats" and I so wish I could search for just that site that I visited 2 years ago.

This extension works well, but I really wish there were simple explanations for why each permission is required. Some are obvious (access tabs, modify bookmarks), but why others are needed is not obvious to me. At some point access to Download files/history was required. Why? I would like to know, thank you.

EDIT: Thank you for the prompt response!

Doesn't save a session automatically. More over it creates blank tabs every time I restore the session.

Update: Firefox 70 and above is crap, does not load many tabs, the problem is not related to MySessions:

I would give this 3 stars (for decent operation, after all it is one of the few workable solutions to kind of replace the really good Session Manager from older Firefox). I was using this problem-free on Windows 7 64-bit at work. I still use this perfectly well at home on Debian GNU/Linux 64-bit (debian sid).
Then, 2 weeks ago I migrated my work Windows 7 machine to Windows 10, and also migrated my profile.
I had refreshed Firefox before the migration, so I had to install MySessions into the new profile under Windows 10.
What happens is that very soon, within minutes to an hour, MySessions stops Firefox from loading, refreshing, saving, or otherwise doing anything with its tabs. I need to disable MySessions add-on, reboot Firefox, can then work as usual, but need to re-enable MySessions if I want to see a tab labelled as "Replaced" (cannot easily load saved content of tab if MySessions is disabled).
I did not find any issue related to this, but if it helps MySessions is the only add-on I have installed.
On Windows 10 we use Micro Trends anti-virus, whereas on Windows 7 the company had been utilizing Symantec Anti-Virus software.
Since it has become unusable after migration, I am unsure if this is related to an interoperability issue with Windows 10, anti-virus software, or to migration issues.
