Data leakage with extension installed.

[ErikGranse]

Hi. I have the extension for this study installed in Mozilla Firefox. The home page for this study says no data will be shared with third parties, but when the extension is enabled (and only when it's enabled), searches performed on DuckDuckGo are transmitted to Google and are present in Google activity history.

I’ve performed multiple searches on DuckDuckGo with and without the Search Engine Usage study extension enabled in Firefox, and when enabled, the search appears in my Google activity and does not appear when the study extension is disabled.
