I use Firefox as main browser, but I discovered for my use case google provides the best results without needing to setup every workstation e.g. 2 home PCs, 1 mobile, 2 for work.

Companies, I based on an idea, but exist to make someone money and if it's tracks it will make many people money and in the end majority will lead the company to earn money and leave the base idea behind.
