Find your browser’s “Add-On” or “Extension” section. AdBlock is not part of the normal browser software, it is an extension. This means it can be toggled on and off through a specific menu, easily found in every major browser:

• Safari: Click on “Edit” → “Preferences” → “Extensions”
• Chrome: Click the three gray bars in the top-right corner, then “Tools” → “Extensions”
• Opera: Click on “Tools” → “Extensions”
• Firefox: Click on “Tools” → “Add-Ons”. Note that AdBlock specifically is not available for Firefox, however this general technique should work for various other ad-blocking extensions/add-ons you may have installed.
• Internet Explorer: Click on “Tools” (may be a small gear icon) → “Manage Add-Ons.” Note that AdBlock specifically is not available for Internet Explorer, however this general technique should work for various other ad-blocking extensions/add-ons you may have installed.
