Although there are a lot of newer and faster web browsers available these days, you might still prefer installing and using one of the oldest and stable web browsers currently available. The general opinion is that it is a slower web-browser but when tested, it is only a few milliseconds slower than the default web browser for Ubuntu systems- the Mozilla Firefox. Other valid reasons to prefer Opera over other browsers include:

  • It comes with a built-in adblocker which is faster than an external plugin that you have to use with other web browsers
  • You can run Chrome extensions on Opera as both are built on the WebKit engine
  • It includes a fast and reliable VPN for many countries
  • The video pop-out feature enables you to run a video in a pop-up video while other tabs are running
  • The battery saving mode lets you save on battery timings
  • It might not be completely open source but its code is available on GitHub
  • It supports fast video loading even for slower internet connections

No matter what is your reason for installing Opera, we will guide you on how to do so through this article. This article lists the following ways to install Opera on your system:

  • Download and install Opera through the command line.
  • Install Opera through Ubuntu Software.
  • Download Opera through an already installed web browser(mostly FireFox) and install graphically.
