Upgrade to 68.0.2-1.

The problem has been fixed upstream in version 68.0.2.

Workaround

Description
===========

An issue has been found in Firefox before 68.0.2. When a master
password is set, it is required to be entered before stored passwords
can be accessed in the 'Saved Logins' dialog. It was found that locally
stored passwords can be copied to the clipboard through the 'copy
password' context menu item without first entering the master password,
allowing for potential theft of stored passwords.

Impact
======

A local attacker is able to obtain stored passwords without first
entering the master password leading to information disclosure.
