[Edit] I found on Github that there is newer release - I am waiting for publish [/Edit]

Since few days it prevents Firefox from start. I can't even figure why. I had removed every old sessions, cleared cache and extension storage and reinstalled couple of times. Checked if there is any conflict with other add-ons, turned them all of and then on again, one by one - and every time I turn on Tab Session Manager browser stops work. Nothing helps.
