GNOME Web contacts the easylist-downloads.adblockplus.org domain the first time it is started up
From https://www.unixsheikh.com/articles/choose-your-browser-carefully.html#epiphany
"A network analysis reveals that GNOME Web contacts the easylist-downloads.adblockplus.org domain the first time it is started up, which I guess is in order to check whether the browser is running with the latest ad blocking filters. On the AdBlock Plus FAQ website it clearly states that AdBlock Plus collects personal information and that this information is used by the company eyeo GmbH (Germany). It is further revealed in the Privacy Policy that quite a lot of personal data is collected."
This makes epiphany a not recommended browser in that list.
