This is going to vary with different people. Have you heard the phrase "Default is destiny"? This is especially true for less technical people (the majority of web users).

Personally I'm not going to dabble, rather keeping to the safe and familiar, so I have to intentionally trial run something as my goto/default.

I've been using web browsers since the mid 1990's and with the exception of when I first started using them I have never only used one. These days I regularly use Chrome, FF and Safari every day for different tasks.

I'm not alone in this. When I peak at other people's computers I regularly see multiple browsers being used there as well. Even the less computer savy people know to use different browers for different websites depending on what works.

This is all to say I don't quite grasp naive understandings of the browser horse races. There is likely little actual switching going on, and the concept of market share in browsers needs to be reexamined.

But this time, the experience was a lot smoother. So it's not a natural switch which happens with time :)
