Restored session is in reversed order or wrong order everytime.Can you help to make this addon restore sessions in right order??
***********************************************************************

Thanks for your solution but it didnt work.I found there is an addon in my firefox called Open Tabs Next to Current,that is why the restored session is in reversed order or wrong order.

CromS, а при восстановлении вкладок не должна ли восстанавливаться история переходов на них? Или текущий API браузера не позволяет реализовать подобную фичу?

PS: И я так понял, что при запуске браузера вкладки не загружаются из последней сохранённой таким образом сессии вместе с историей переходов. Верно?

During normal browsing, works as expected but not during private browsing.

Firefox crash during during private browsing. Last session before the crash is saved under crash recovery. I believe this is not a normal behavior.

This session manager works perfect for my needs. The regular updates with new features and quick fixes gives me hope that this extension won't be abandoned any time soon. I highly recommend it if you're in need of a reliable session manager.

Since the last update my auto save session does not work. Any ideas??

the ease of use and the reliability of the software coding also the fact that tough it has a few bugs in it to be worked out the developer is constantly reviewing our opinions on his program add on and applying the overall consensus to updates

I recovered after a hard disk failure. Thank you. Accept a donation by paypal.

Handy extension to have....in theory. However,it prevents TreeStyleTabs from functioning,and has a regular habit of locking up absolutely everything on this PC,including Ctrl-Alt-Delete,which obviously means hard reboots are the order of the day.

I'll stick with it for the time being though,as it's still early days for developers trying desperately to clear up the awful mess that the 12 year old Korean kid with aspergers and OCD (zero empathy for anyone else of course) caused when Goog.....erm..sorry....Mozilla presumably employed him or her to wreck the basic functionality of their browser.

Autosave and crash recovery stopped working for me since 15/7/2018. Any suggestions how to fix this?

*Update*: working again, thanks for the quick fix.

This addon saved my life :D Stupid Mac has updated and closed my Firefox, which for whatever reason has lost my session afterwards, and the sync of tabs from Mac - again, for some bloody unknown reason - was completely lost from the list of the devices I use (this is, I believe, Firefox's own fault)!

I was already devastated because Firefox inexcusably dropped support for two biggest life-saving add-ons - Session Manager and Lazarus, and was regularly checking if they will be re-enabled until recently, when I gave up and just started considering completely switching to Chrome. (Meanwhile I have found Cyberfox which is like an older Firefox version which supported these add-ons :D )

I went to check the add-on market (which had only one extension compatible with Firefox Quantum, and of low rating), and found out that a few more have popped, and decided to install this one - I was so happy when I found out that it supports Session Manager's session backup files and that it actually worked! It wasn't the latest session, albeit (because I had no means of saving it!), but still recent enough so that I got back my tabs for learning stuff.

If there is any decent replacement for Session Manager, it is MySessions. Thank you!

Ich stimme zu. Beste Session Manager.

This add-on is absolutely essential. In the absence of the proper API required for saving sessions, this is by far the best that can be done. It saves sessions as bookmarks, which means there is no need to export sessions, as they are conveniently stored in the bookmarks file, backed up regularly by Firefox internal engine. Managing the sessions is also more convenient, using Firefox's internal bookmark manager.

The only down side is that tabs' states are not recorded (filled form fields, containers and so on), but that's a minor trouble compared to losing all windows and tabs when Firefox's internal session manager fails (and it fails a lot!)
