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.
Edit: Please be aware that the spyware article on Brave (and the rest of the browsers on the site) is outdated and may not reflect the browser as it is today.
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 a fortune from its users who will likely lose their money.
Edit: To the people commenting saying how Brave has a good out-of-the-box experience compared to other browsers, yes, it does. However, this is not a warning for your average person, this is a warning for people who actively care about their privacy and don't mind configuring their browser to maximize said privacy.
Due to some specific hardware issue on my end affecting all firefox based browsers, I have to use a hardened and stripped down version of Flatpak Brave, which I did manually, as a backup browser. I used to use Ungoogled Chromium but it is not reliable. Other than that there is absolutely no reason to use Brave and I would immediately switch back to Firefox only if I get newer hardware.
As a plus point, firefox (gecko based browsers in general) are the only ones I have seen which provide the best theming flexibilities.
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.
