You'll have to explain what you just posted to us dolts and what it means to seniors. Other reviews I read gave it a thumbs down because of the promises that didn't make grade. Firefox/duckduckgo does everything I need. I have very, very few ads, no pop-ups & had only one issue back in 2015 that taught me to not use the same password with 2 applications. I adhere to the KISS approach.
There are researches done on popular browsers regarding how much telemetry they use, in layman's terms, how often a browser "phone home" to the browser developer, whether it's to keep itself up to date and tell the user when a new update is available, collect browser settings for troubleshooting/improvements, etc and they've found that Brave does it the least. The problem is you never exactly know what data is being sent and what it contains, with or without your knowledge. It could be just user settings and some basic hardware specs, or it could be an entire list of websites you've ever visited. Internet Explorer/Edge, Chrome and Safari are the biggest culprits.
What seems to be the consensus of Brave and Firefox users is:
Brave does privacy protection better than Firefox out-of-the-box, meaning you don't need to adjust or change anything. Great for people who are used to Chrome but want a safer browser and novice users in general.
Firefox doesn't do privacy protection as well out-of-the-box but with some tinkering, it can have stronger security and better privacy protection.
Both options are great so you can't go wrong with either of them. But I feel I have to point out that both browser developers have been embroiled in some controversies (unrelated to their browsers) in the past that may or may not have affected the direction their browsers are heading and their future.
