What happens when one does a new attempt at a browser, that cannot be merged into the original major browser when it gets big enough?

For a simple example, suppose Google Chrome was the only major browser in such a model. One day, someone decides that C++ is too prone to vulnerabilities, and creates a new browser, called Firefox, based on Rust (on an entirely new codebase). What will happen when Firefox becomes sufficiently large to be considered major?
