Firefox Hardening

Description

A CIS based Hardening for Mozilla Firefox browser.

• There are 6 level 2 rules (with potential impact) marked in the scripts
• Easy to use (2 solutions)
  • Run script (PowerShell for Windows, Perl for Linux)

• A keepass configuration (the web content can't deactivate copy/paste events)
• Privacy configurations (tracking protection, URL bar "smart" options...)
