Anybody yet observes this alert?
TBB-3.6
Everything worked fine before, and then suddenly alert message box. Last automatically updated add-on was Noscript 2.6.8.23
Debugging showing that exception generated by
browser.addTab("about:blank");
from torbutton_close_on_toggle()
Can't reliably reproduce this bug, everything works and then for the same sequence of actions this fail appears.
