I have seen many people in this community either talking about switching to Brave, or people who are actively using Brave. I would like to remind people that Brave browser (and by extension their search engine) is not privacy-centric whatsoever.
Brave was already ousted as spyware in the past and the company has made many decisions that are questionable at best. For example, Brave made a cryptocurrency which they then added to a rewards program that is built into the browser to encourage you to enable ads that are controlled by Brave.
After creating this cryptocurrency and rewards program, they started inserting affiliate codes into URL’s. Prior to this they had faked fundraising for popular social media creators.
Do these decisions seem like ones a company that cares about their users (and by extension their privacy) would make? I’d say the answer is a very clear no.
One last thing, Brave illegally promoted an eToro affiliate program, making (presumably) thousands of dollars off their users.
Have you tried any forks of Firefox? They might serve you better. You could also try out Mullvad’s browser, which released a few months ago.
I have tried a wide number of Firefox Forks, some niche ones as well. I generally do not prefer non-ESR releases or Forks because of the added Fingerprinting Risks. But all of them had the same issue so I concluded that there was some incompatibility with my Hardware (which is quite old now) and the Gecko Engine.
