I tried out the Opera browser based on several users mentioning it here. However, I had two concerns about it, so I uninstalled it after using it for a couple of days.
First off, it seems to work pretty good, and I had no issues browsing various sites. The bad: When first installing it, it asked what I wanted to import from my other browser. I specifically unchecked saved passwords, but it did so anyways. After seeing that, I wanted to see who owned it, and it appears it was purchased by a group of Chinese investors in 2016. So after those two things, I uninstalled it.
