I’ve been using Firefox on desktop and mobile exclusively for a number of years now. I will say the experience isn’t perfect but it’s better than using a browser made by a company that is actively hostile to its users.

It is important to take note that you will experience issues with some websites. For example, https://astro.build/ Try scrolling quickly up and down on this page on Firefox vs Chrome (on mobile).

It’s far better to use this site: fingerprint.com/demo

they are one of the largest actual/commercial vendors of fingerprinting software. their business is to track you.

please try it with brave and post your results. i could be wrong but last time i checked brave failed this test. arkenfox doesn’t even allow the tracking to load which I consider a pass although you could argue that just because the results don’t load doesn’t mean they aren’t able to track you in some way
