You can trust or distrust whoever you want, but I wouldn't be so quick to dismiss Firefox. They now have updated the wording of their TOS that caused so much uproar and confusion (in part fueled by Brendan Eich, who runs a competing browser) and are pretty clear about what they do.

Firefox also still supports Manifest V2, which lets you use the full, ultra-powerful version of uBlock Origin. There's no better privacy protection than uBlock.

Firefox is a much better choice than any Chromium based browser for the privacy conscious.
