O melhor. Muito completo.

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.
