 It is currently possible to use TB before and while downloading update. It
 is a grave security risk in case of 1-days.

 It is proposed to disallow navigation in the following cases:
 1 update is available, containing vulnerabilities fixes, but not yet
 installed. In this case update downloading progress should be displayed
 and the list of vulnerabilities fixed in the update.
 2 It is unknown whether update is available.

 In all cases the message must contain some text explaining why it is
 important to wait until the update process is finished.
