[FIXED] AdBlock for Chrome isn't blocking ads on any site after a recent update

Oops. We discovered a bug in our 3.17.0 release of AdBlock for Chrome that causes AdBlock to behave as though it's paused when it isn't. The AdBlock button in the browser toolbar is still red (when AdBlock is paused, the button turns green), but every site seems to be whitelisted.

That's because every site is whitelisted. The bug inserts a "universal whitelist" rule―@@―into AdBlock's custom filters. While that rule is present, AdBlock will not block or hide ads.

How to know whether the bug affects you

If you're suddenly seeing ads again (or hearing ads on Pandora), click the AdBlock button in the browser toolbar and select Options. Click the CUSTOMIZE tab and look at the custom filters box. Do you see "@@" on a line all by itself?

If the answer is "no," this article won't help you. The "@@" bug is not the reason you're seeing ads. Please see this article instead.

If the answer is "yes," then the bug affects you. Keep reading.


We'll have a bug fix update available in the next week or so. There's nothing you need to do. Your copy of AdBlock will update itself automatically.

In the meantime, please use one of these workarounds.

Easiest: Pause and unpause AdBlock

Pausing, then unpausing AdBlock removes the universal whitelist rule from your custom filters. Do this after you open Chrome.

Click the AdBlock button in the browser toolbar and select Pause AdBlock, then Unpause AdBlock.

Alternate method: Delete the rule yourself

In AdBlock's options, CUSTOMIZE tab, delete the "@@" custom filter.

  1. Click the AdBlock button in the browser toolbar and select Options.
  2. On the CUSTOMIZE tab, click Edit.
  3. Delete "@@" and click Save.

We're sorry we missed the bug and for the inconvenience it's causing!

Seeing ads everywhere but you don't have the "@@" rule?

We have some suggestions to help you troubleshoot unblocked ads.
