Web Browsers:

Browsers that I have installed on Windows: FireFox, Chrome, Edge, Brave, DuckDuckGo, and Tor. And not Safari because they abandon Windows support. On mobile (Android) I use DuckDuckGo. I do not use Linux, macOS, nor iOS.

Which browser should you use? If you care about privacy, probably Brave. I use FireFox as my primary browser (for other reasons) but have it pretty well locked down (for privacy) with add-ons. If you don't care about privacy at all, use Edge or Chrome. I prefer Edge between those two. I also use the DuckDuckGo browser on Android. For ultimate privacy, but slow speeds, use Tor.
