This release adds support for the experimental CSS properties syntax to Adblock Plus for Firefox (issue 2401, issue 3955). This support isn’t complete yet, most important issue being that hits are not counted for CSS properties filters (issue 3969).
• Fixed issues that Adblock Plus could potentially cause on Firefox startup (issue 2850).
• Some first-run page optimizations (issue 2668, issue 1292, issue 3736, issue 3814).
• Cleaned up internal messaging approach (issue 3499, issue 3851, issue 3853).
