So I'm trying to get away from all contact with Google services. I've changed my browser to Firefox, search engine to duckduckgo, block 3rd party cookies etc. 6 months ago I looked at a website that I don't usually visit. Then last week I did a YouTube app search for a specific video and soon after the Firefox on android home page was showing the website I'd visited 6 months ago. I searched my Firefox history for last week and there nothing to say I'd searched for the topic. So this mustmean Google and Firefox are sharing data even though we explicitly go out of our way to avoid this. This means Firefox is not a privacy focused browser.
