Content Blocking can be used to block any content on a page, including images, plug-ins (like Flash), videos, scripts, styles, and other resources. To block content, a user must right click on the page, and click "Block Content". It's then possible to simply select the elements you wish to block. Users can also control how much they want to block expand using URL's with wildcards and such. Opera stores its content blocking URL list in a file called urlfilter.ini. Several internet sites provide a regularly updated urlfilter.ini already loaded with the web's most common advertisements so users can block ads using the built-in feature. The users are able to sync the content blocker list using Opera Link.

At a cellular level, vanoxerine acts to block cardiac ion channels. Vanoxerine is a multichannel blocker, acting on IKr (potassium), L-type calcium and sodium ion channels. By blocking these specific channels, there is a prolongation of the action potential of the cell, preventing reactivation by a reentrant circuit. The block is strongly frequency dependant: as the pacing of the heart increases so does the frequency of ion channel blocking by vanoxerine.
