I do agree that most of the detail gets lost. At least for me when the icon is smaller than 30x30~. I personally dislike the the simplification of the new icon makes it feel like it lacks any personality. I specifically miss the globe more then anything else. The globe made it feel like a web browser too me without it I wouldn’t even known what it was the first time I saw it.

At less for me the newer two logos makes it feel more like a brand then a piece of software with a cute avatar.

I don’t know how how to express my feeling and reasoning for my feeling into words.
