Try Opera or Opera Mini to see the difference.
If you are new to content blocking in Opera, see tutorial.
Easy way to block ads is to disabling the IFrames & JavaScript globally and enabling them for required sites in site preferences.
To block particular JavaScript or IFrame ad in a page, open info panel, note path under Scripts or Inline frames and add it to content blocker.
To block flash use Flashblock for Opera 9.
From Opera 9.50, you can enable/disable content blocker globally using Block Ads button or per site basis using site preferences.
- Large urlfilter.ini file will increase startup time of Opera.
- You will get blank page when you try to visit a site blocked by content blocker in version below 11 and the following message in version 11.
Web Address Blocked
The address XYZ is blocked by the content blocker. To undo the block, open the context menu for the page, select the content blocker, and remove the address from the list of blocked content.
To undo the block, right-click on the page, select "Block Content", and click the "Details" button to edit the list of blocked content.
