Mozilla Likely Been Sharing Aggregated Firefox Data with Advertisers Since 2017 (quippd.com)
TL;DR: With Firefox 56, Mozilla combined Firefox Health Report and Telemetry data into a single setting called “technical and interaction data”, which was then enabled by default. This included data about advertising within Firefox’s New Tab page, along with a lot of other technical information about the installation of Firefox. The Firefox preferences UI makes no mention of usage of this technical data for advertising purposes.

Verifying Firefox Sync privacy claims (afarah.info)
Recent controversy and a history eroded trust on Mozilla's privacy claims for some, with commenters worrying about Firefox Sync, which can synchronize your browser history etc between devices, relying on Mozilla servers for it.

Use Firefox in 2025 (alexn.org)
I grew up with the Internet, since before people had Internet connections at home or in their pocket. The browser, being the window to the open web, holds a special place in my heart. In this article I’m suggesting the use of Firefox in 2025, for both technical and political reasons, as it’s still the “user agent” that it set out to be.
