Alles was man braucht und nach mehreren Updates noch besser als der Vorgänger!

I'm very thankful for this addon as my WebExtension substitution of Session Manager by M.Kraft. I've used it since the beginning and I have never had any issues.
However, I've come to the point where sessions sync is the must have. This is why I have to change your great extension, despite that I like its UI and much more than the others.
Farewell and good luck! :)

Below is my original review 9 months earlier:
I am glad for the effort to bring Session Manager to WebExtensions. Still, in some cases I am using one instance of FF ESR with original Session Manager by Michael Kraft for its superior functions:
- auto saving sessions
- saving either whole session or just a particular window (what's even more useful for me).
It would be great to see the above in Tab Session Manager.
I also hope to find a top notch cooperation with Multi Account Containers, like auto saving window with a particular container tabs, so I can always start or exit my Personal, Work or other Container window and have my session saved.

This addon has improved dramatically over the past few months and the value is very good. The only thing I feel it lacks is sync option.

оченб удобно,спасибо разработчику.

In Mac, its a normal behavior that closing the firefox window by clicking the red button closes all the tabs while keeping firefox running in background, so automatic session restore does not work unless firefox is quit using Command+Q. Is it great that restoring the session that was closed the last works great with this add on. However is it possible to restore the session automatically from the last closed or autosave (whichever is latest) state when firefox is started when there was no firefox tab-window left (browser window only, ignoring the download, histrory, bookmark window or even the firefox program running in the background as the case with mac). This will make closing and restarting firefox window in mac so smooth, you may make this feature optional in the setting.

FRQ:
1. Restore last closed state or or autosaved state which ever is latest, when firefox window opens when there is no existing firefox browser window. (this makes it more intuitive to close firefox in mac using the red button and restarting).
2. Retina compatible high resolution logo of the add on, and may be a change of color of logo.
3. Relative time in the session list, such as 15 minutes ago, 1hr ago in addition to the existing timestamp.

Keep up the great work,
Milan

好东西！可备不时之需。。。

This add-on works perfectly for me. I use it every day. Thank you VERY much for adding the "save position" functionality. I missed this feature a lot. But now everything is just perfect.

Getting better and better with every update. Keep up the good work!

Simple but perfect. Nice work ;)

I love it because i don't have to remember what I was doing when I have to reboot or something, etc.

It's getting better! Much more convenient with exporting session and importing sessions, as well as the NEW added to ability to edit a saved session and delete any tabs from the saved session! Keep up the good work!

This addon does exactly what I want. I could not ask for anything more. The settings are easy to understand and configure. It is an amazing addon for all users who juggle with different windows with tons of tabs open on each of them.

Last update give us a few very useful features like removing links or whole windows from session without need of load it, and easiest way to replace session. It made addon very convenient. Unfortunately I don't have paypal in my country so I can't donate to it =(
