Search engine: Firefox.

Reasoning: Cuz me favorite animal is the fox and privacy.

These are browsers >>

I used to use something called "Iron" which was just Chrome but without the whole tracking your every move aspect of it. Iron stopped working well for me, however, so now I just use Chrome. Dont like the personal NSA they have but it works well. On mobile I just use Samsung Internet. It works, so I'm not gonna even bother screwing with it.

Search engine wise, I used to use something called DuckDuckGo for the same reason I used Iron, and stopped using it for a similar reason. Now I just use Google.

whats opera?

I use internet explorer and google chrome incognito tab to study and do real important research about biology stuff.

Chrome and Firefox are a split decision for me. I really like both of them.

None of those are search engines
