    The advertisements we keep seeing on the internet all the time could be a serious pain. There are some ads that end up linking themselves to some malware, this is called malvertising. These ads become the barrier that doesn’t let you access the content you wanted to view, with ease. Also, the advertisements are also downloaded by your device thus pushing up your daily data usage which can be a problem if you are using a limited data plan.

    The solution to all these problems is an ad-blocker. Ad-blockers are added to the browser to hide ads, they apply the community-generated filter list, and ads are blocked.

    As these filter lists are not perfect, you can always get an ad once in a while but ad-blockers like uBlock Origin will allow you to manually block ads that coincidentally appear.

    uBlock Origin

    uBlock Origin is an ad-blocker that is free and available for all the major browsers. You can also find an element picker in this tool that removes custom elements.

    If you have some knowledge of CSS or Xpath, it will be helpful to you while going through this article, but it isn’t mandatory.

    uBlock Origin will provide you with the visual tools which you can use to select elements without having any technical knowledge.
