Opera FAQ's, Tips, Tricks & Tweaks

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. Tools → Preferences... → Advanced → Content → Blocked Content... → Add...

From Opera 9.50, you can enable/disable content blocker globally using Block Ads button or per site basis using site preferences. F12 → Edit Site Preferences... → Content → Enable content blocking
