Google chrome
Google is my favorite brand. Google provides a lot of tools for developers and everyone generally. Google chrome is a very important tool not listed. I can browse as a guest or incognito. I can synchronize history, bookmarks and passwords on my mobile with my pc. I can also save my passwords and form autofill for free. It also has the best features for web developer. So much features like no other.
I wish google map and interpreter were listed too.
