Firefox

Free

Price checked at source August 28, 2026.

The independent, non-profit-backed browser — tracker blocking on by default, no shareholders to answer to, and Mozilla says it never sells personal data.

Our take

The clearest privacy-by-default pick among the mainstream Mac browsers: tracking protection is on out of the box rather than an extension you have to remember to add, and Mozilla’s own pitch is explicitly “not owned by shareholders.” Switching brings bookmarks, passwords, and history over from another browser automatically.
