A fair toss every time
Each flip is an independent 50/50 draw from the browser's secure random source. Real coins are very slightly biased by their weight and the way they are thrown; this one is not.
Getting heads five times in a row does not make tails more likely next time. Each flip starts fresh, which is why streaks happen more often than people expect. Flip 100 times and you will usually see a run of six or more of the same side.
