This problem is not totally deterministic, but in some cases occurred that adding to the overflow one extension from the toolbar context menu, unchecks the pressed browserAction.
Apparent behaviour only on some transitory status of the code. Not being able to have it reproduced any more. Closing the issue unless being able to detect it again.
