I have been a happy Firefox user for 15 years... maybe more. I have seen people use and complain Internet Explorer in my younger days, from version 6 to 7, etc. Even though I mention Firefox to them, they stay with IE. What amazes me is how quick they transitioned to Google Chrome when it released. This was around 2009. It amazes me how quick people jump to something especially when it has a big company behind advert…
When Chrome originally released firefox was better than IE but chrome was head and shoulders above both of them.
Moving to Chrome from firefox at the time was a breath of fresh air. Nowadays there's very little difference, there was a short period of time I found Firefox faster but now I doubt most users would be able to tell the difference in performance
