Problem with FF 64.0b4 and TSM 4.2.0:
Option: "Use the "discarded" property"
prevents to open more then one window!
Otherwise a very usefull addon.

Excellent add-on. I use it to manage the ridiculous number of tabs I (usually) keep open. The save window tabs, save session, auto save, and auto backup have saved me from a ton of headaches. The developer seems to update fairly often and responds to user issues. I will be sending a donation as soon as I get my next job. Much ♥ sienori.

OK.

Thanks for the great plugin!
Worked always flawlessly for me.

Don't worry too much about the low-ish rating. People lost one session (which was possible to get back) and they're too mad to read about how to fix it.

Ottima! Very useful! Thank youm 1mill!

We just need a dark mode

semplice e stabile. fa il suo lavoro.

Funktioniert wie es soll. Bin sehr zufrieden.
