The most popular browser, I believe, is Chrome, which I used for years and liked, but it was/is a memory hog. What is a good alternative browser, you might ask? This article discusses this question, and compares the attributes of three alternative browsers: Vivaldi, Opera, and Brave.
I've used all three, thought all were fine, but have settled on Brave as my browser of choice, at least for right now. If interested, read the article to see what you think.
