Opera is a very unique browser. Its interface resembles that of any other Chromium browser, but with several major changes. The first of these is its sidebar. From here, you can access many of Opera's features, like pinboards. Pinboards is a tool for saving webpages, taking notes, and sharing interesting things. It can be accessed from the sidebar using the pin icon. Another unique feature is Flow, which allows you to share files between connected devices. Opera also has the ability to use multiple workspaces, letting you organize your tabs. Each one is like a separate browser window. You can switch between them using their icons in the sidebar. 

The address bar is very sleek. It is similar to other Chromium browsers, but has no outline, so it blends seamlessly with the surrounding interface. The icons for several other features, such as Opera's tracker blocker, are located on the right side of the address bar, as is the quick settings icon. This icon opens a panel where various settings can be configured. Next to this is the battery saver. The Opera browser can reduce its power usage to prolong life when your computer is on battery. 

In terms of privacy, Opera is ok, though it is outperformed by other browsers. I tested it on safety.google and weather.com. On the Google site, it blocked 2 trackers, while Brave blocked 6 and Safari blocked 4. It did significantly better on weather.com, blocking 7 trackers and 11 ads, while Brave blocked 15 and Safari blocked 12. Its main limitation is its dependence on a small set of blocklists, while other browsers use much larger lists and tracker-detecting AIs. The privacy policy is ok, but nowhere near as strong as those of other browsers like Vivaldi. You can read Opera's privacy policy here. There have been privacy concerns raised due to Opera being purchased by a Chinese consortium, but they appear to be unfounded.

Overall, Opera is a pretty powerful browser. Its wide array of features makes it a good choice if you like browser functionality. While it may not be the most private browser, its privacy is still pretty good, and it is much better than Chrome.

Installing the browser is very simple. Go to opera.com and click 'browsers' on the navigation bar. Select the option that just says 'Opera', or click the 'download Opera' button on the homepage. If you install from the browsers pop-up, you will see an article about the browser with a download button at the top. Click it, then save the installer to your desktop. Open the installer and follow the instructions inside. When you are done, open the browser.
