ELI5: How can one web browser be faster than another?

Super ELI5 answer: Imagine you gave two people a box of Lego and a rough picture of something you wanted built, you can build that many different ways and with varying degrees of efficiency, both will get it done but one technique will come out on top.

As with most things, one technique isn't the absolute best way to go about it, so while say (rough example) Chrome might be better at multiple tabs because it keeps all its Lego blocks (tabs) on separate bases, Firefox might be better at one or two tabs because it doesn't have to stand up and move when it wants to go and work on a different Lego construction.
