Was a 5 (will have to drop soon). With the 3.0.0 upgrade on 2018March20, on Firefox 58.0.? and then soon after on Firefox 59.0.1 (64-bit version) on Windows 7 Professional, the clicking on the Add-on icon in the toolbar, the saved session navigation tool would display but would be blank (I have a lot of saved session, so I pretty miffed for a little bit). I tried to save some new ones, to no avail.

That said! After futzing around with pretty printing the storage.js file appears to be intact, and the Add-on appears to be auto-saving the various tabs on the defined interval (15 minutes, I think).

I'd love to see a fix appear, because I really don't want to have to write a perl script to extract all of those backslash escaped URLs in the file (or do it by hand! :-O )

Thanks for a (usually) great tool.

Fait le job, interface claire et intuitive.

This is a great add on! Thanks!

Really really useful - after the old addon stopped working I was left without feature that is absolutely crucial for me as I always have billion tabs.

I would like restoring the content of text boxes too, similar to the "Show your windows and tabs from last time" Firefox setting.

I'm not sure why this has such a low rating. Sure, it isn't as good as Session Manager was in the old Firefox Add-Ons, but it's the best replacement there is and it's improving all the time.

Perfect add-on. Save your sessions as you want.

Einfach klasse!!

Awesome addon! FireFox ver. 57 came out only a month after I discovered the incompatible Session Manager addon, and it was disappointing to stop using it right after finding out how useful it is. This addon is a WIP Session Manager replacement for FF 57, and so-far it works great. The best part is that I can directly import the sessions from SM I had saved, which is super convenient. Other people seem to be having some problems and it doesn't have all the features that SM had, but it works fine for me.

Thought I lost all my sessions but it looks like they were just hidden.
