Right, been doing some testing and noticed lately that filtering randomly fails on Amazon.com when searching for items. I've tested this with only the English filter and Spyware filters enabled. Steps to reproduce: 1. Go to http://www.amazon.com/ 2. In the search bar, search for any random item. 3. Scroll down to the bottom of the results and if sponsored links appear, filtering has failed. Also the assistant doesn't show up when the filtering fails. If you don't get it to work, just repeat steps 1 and 2 until it happens. For me, I usually put in ear buds into the search box and sometimes it'll fail. My guess it's a bug in Adguard itself causing this issue.
