With Opera Software's move to Chromium came a new Discovery feature that debuted first in the new Opera mobile versions before it was integrated in the new Opera 15 for the desktop as well.
Discover provides you with a selection of news based on topics of interest. The feature is accessible from Opera's new tab page. Just click on Discover here to open the top stories page listing news from mainstream media on it.
You can change the display to a topic of interest, e.g. technology, business or sports, or customize the top stories page by selecting what you are interested in and in which language and for what country you would like to get those news.
What you get basically is a selection of articles from popular news sources, an aggregated online newspaper so to speak.
While some may like the idea, others may find it to restrictive in terms of news that the service selects to be displayed to users, or too generic when it comes to the selection of news sources.
Even more problematic than this is the fact that these contents get preloaded by the browser. So, even if you are not using the Discover service of the Opera web browser at all, it is retrieving information from the Internet so that Discover news items can be displayed faster should you open them in the browser.
It makes sense to disable the feature if you are not using it at all, and the latest Opera version comes with a switch so that you can do just that.
You can disable the preloading of contents in the following way:
Opera will stop preloading contents from that moment on. Note that contents will still be loaded if you select the discover tab on the new tab page.
