This. I don't get it why people point out on and on the same three mistakes that Firefox team made in the past. In case of Cliqz, I guess they want to say: "I am not going to use Firefox, because it sends browsing history to Cliqz". Isn't that a bit weird? I agree, that was a mistake and Firefox does not have crystal-clear history, but in case of Google Chrome I am not really sure how Google collect, enrich and manage my data.
Personally, I can only notice two advantages of using Google Chrome over Firefox these days: a developer console and it is "faster" to develop websites targeting only one browser. I think I just got used to dev-console in Chrome, with each release the new developer console in Firefox is way better. About the second, it still doesn't matter much, because we have also mobile browsers, which also takes a lot of our precious time during development. Is there are any other unique selling point of Chrome which I've missed?
