Things to consider…

Are there enough extensions?

> Secure browsers often restrict the choice of available extensions and plug-ins. If they don’t, it’s important to ensure that you’re not undoing the browser’s good work by running privacy-breaking add-ons.

Do you need it to sync between devices?

> Some of the browsers have iOS/iPadOS versions or versions for other platforms that can sync with your Mac’s browser.

Are you sharing stuff voluntarily?

> No matter how secure, browsers can’t stop you from sharing data if you do it voluntarily. Don’t use social media accounts to log in to other websites, and be careful what personal data you give to sites.

Do you need a VPN?

> Some browsers can hide your address and traffic, but only for your web browser. If you need to use other apps privately too, you’ll need a dedicated VPN.
