I currently use firefox with duck duck go on all of my devices. Yeah. Firefox has very good add ons like 'Https everywhere'. I hate google products, so, firefox is set as my main browser.When I said, "Secure your Browser' ....if you use Firefox there are many add ons to make it secure
You could install Brave Browser.
It has inbuilt ad blocker and tracker blocker, it automatically upgrades all connections to https, and has fingerprinting blocked.
It takes around half an hour to go through all the settings, but it is time well spent.....and it takes a load off your mind.
I use it, because it is secure and because it is quick.
Set it as default web bowser and a good part of your security worries are taken care of.
Firefox also have inbuilt tracking blockers. I have never really used brave browser, but I saw it has very good ratings on internet. I am installing an VM right now to install windows on it, so, after ur comment, I decided to install brave browser and try it on windows. I'm addicted to firefox, but I also like to try brave too.
