When you open the app, it starts with a little video that Opera says is a little reminder of how the internet should be. That's a pretty good way to start things off. After the video, you're brought to a page that looks a lot like Google's, but with a few different options. The first thing you'll notice is the "VPN" and "Adblock" options in the upper left corner. If you're not familiar with either of those, VPN stands for Virtual Private Network, and it basically encrypts your traffic so that your ISP (Internet Service Provider) can't track what you're doing. Adblock, on the other hand, blocks ads from websites. That's useful because ads can be used to track you as well.
After you've chosen whether or not to use VPN and Adblock, you can start browsing. The browsing experience is pretty similar to other browsers, but there are a few things that are worth mentioning. First of all, the speed is pretty good. I didn't notice any major slowdowns while browsing, even with both VPN and Adblock turned on. Second, the battery life is also pretty good. I was able to browse for a couple of hours without noticing any major drain on my battery.
As for privacy, Opera seems to do a pretty good job. I didn't notice any major problems while browsing, and both VPN and Adblock seem to work well. Overall, I think Opera is a pretty good browser. It's fast, private, and has a few extra features that are useful.
