Having trouble with AdBlock?

Sorry to hear that! You've come to the right place.

First thing:

Make sure you have AdBlock installed and have the latest version. Chrome instructions, Safari instructions

Next: is this your problem?

• Are you seeing infinite error message when you start Safari?
• This is fixed in AdBlock 2.4.33. After force quitting Safari, you can uninstall and reinstall AdBlock to fix the problem.

• Are you seeing AdBlock's install screen every time you start Safari?
• This is fixed in AdBlock 2.4.33; update AdBlock for the fix.

• Are you seeing broken image popups or slideshows in Safari?
• This is a Safari bug that will be fixed in an upcoming version of Safari.

• Are you seeing ads in videos or Flash games in Safari?
• This is a known limitation in Safari. Only Youtube videos get their ads blocked, and then only some of the time. You can install Chrome on your Mac and then AdBlock For Chrome to get ad blocking in videos/Flash.

• Are you seeing Flash ads in Chrome 21 (dev)?
• This is caused by a recent bug in the browser. Please star Chrome issue 128347 and hope they notice it.

• Are you seeing some other ad that should be blocked?
• To report the ad, please use the reporting wizard.
