Many extensions designed to scrape data from social media websites are disguised as simple extensions that do something else.

If I had to guess: I sought that automatic content blurrer, neurodivergent website simplifier, or anti-Zionist tagger actually work. They’re all just piggybacking on trending topics to get users to install them and then forget about them, then they exfiltrate the data when you visit LinkedIn.

This. Do not install any extension unless you absolutely need. Assume they all leak your browsing data. Not familiar with Google but if you can just vibe code your own extension then do that.
