Comment (by isis):

 Replying to [comment:2 harmony]:
 > In the course of resolving a help desk ticket in which the user claimed
 to have permanently disabled this warning across TB sessions, I tried to
 use about:permissions to view/change the stored preference, but nothing
 showed up. I advised the user to reinstall Tor Browser, but I don't know
 whether there is a more efficient way of doing this.

 I forgot this ticket already existedâââthanks for finding it, harmony!

 The user ''should only need to restart'' Tor Browser to reset all canvas
 permissions. If a complete reinstall is needed, then that would likely be
 another bug (because it would mean that Tor Button is not properly
 clearing all browser state when "New Identity" is selected and/or when the
 browser is restarted).
