I like my privacy, it is something I value and when I saw that Mozilla produced Firefox Focus, a browser for Android that does a better job for your privacy I wanted to test it out.
I installed it and went as usual straight for the settings, where I had a little disappointment. The default search engine is Yahoo and not Duckduckgo and instead of an opt-in you have an opt-out for sending anonymous data. For the rest I turned all options on to block as much as possible.
I visited a couple of websites and must say that it ran smoothly and if you think about it, you are pulling down less from the Internet so that means that you will consume less of your data plan.
If I run in any trouble I will write a follow-up but up till now, there were no issues.
