Frequent updates & nice, clean interface. Haven't had any problems.

Makes functions more accessible!

сделайте возможность, чтобы в пользовательские сессии можно было добавлять отдельные вкладки
make it possible to add individual tabs to existing user sessions

Hi, this Addon is very useful, but can you please fix the display of the "favicon"? if my session is restored, all tab-icons are missing. They'll refresh when i click on tab, but i want them always. Thank you!!

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.
