I use Opera browser with it's built-in ad-block feature to browse most sites. But I use Chrome for Gmail and web apps. Never researched the issue, so I don't even know if Opera is considered to be particularly good. It shows 10-30 blocked ads on the average site. I particularly dislike auto-playing video ads. Would be interested to see comments by HNers who have done some research into ad-blockers.
