Opera is one of the most refined piece of software engineering and if not the world's fastest webbrowser it is definitely one of the fastest and securest web-browser around, despite Opera being my favorite browser I personally use Firefox simply because of the expansion possibilities if offers by means of add-ons specially the Ad-Block Plus extension allowing automatic filtering of unwanted content with ease, luckily Opera 9 features a powerful content blocker to mimic the Adblock Plus functionality, To block an image, frame, or Flash animation you simply need to right-click an empty spot on the page and select Block content menu item, Then, click the images/content you want blocked, When finished selecting, click Done as shown below.

Similar to the Filter list feature in Adblock Plus you can also add pre-complied common ad-blocking patterns to Opera for a clutter free web-browsing experience, follow the simple instructions below to implement ad-blocking in Opera.
