The largely dominant browser is never "easily replaceable".
We could write PHD thesis about why, but we can take a meta look at it: there's reasons they became dominant in the first place, and those reasons need to disappear before it's easily replaceable (of course additional reasons will pile up the longer the browser stays dominant)
