I use mostly Firefox or Via. Via is fast and works great with older devices.
It's not a browser per se but Newpipe for youtube, sadly doesn't work with the red one.

In that case, I use Firefox on Android because it is rather easy to delete all cookies/cache/offline data etc. on it, even to set it to delete them whenever I exit the browser.

I use Chrome as well as my main web browser on laptop/desktop. I know Google is the worst when it comes to being intrusive, but since I use Gmail I love that I only need one account for everything Google related. I use the extension ad block within Chrome.
