The bookmarks are a mess and the way it opens a new tab whenever I tap on a frequently visited site icon. Those two things drive me nuts. Especially the bookmarks.
I was looking at browsers in the Play store and saw the Ghostery browser. It's now apparently based on Firefox, and I assume the Ghostery (plugin/extension) functionality is built in. Does it protect privacy better than other browsers and is it worth trying out? I currently use Firefox on android but I detest it's UI decisions. I've no idea if Ghostery has a different UI or not.
I tried using Searx a while ago but it always got blocked by the search engines. Your mileage may vary.
