There are a number of other crypto coins that can be mined via the browser, most notably Nimiq which uses an algorithm (Argon2d) that is ASIC resistant meaning in theory it should be even more profitable for normal day users without high end GPU systems to mine. Nimiq itself is making some pretty interesting tech implementations such as being written ground up in Javascript and rewriting core parts in Rust so it will run in the browser via web assembly. Their code base is worth checking out: https://github.com/nimiq-network/core

Looks like they've already added GPU mining as a MainNet milestone. (https://github.com/nimiq-network/core/issues/39)

Firefox is probably slower because it uses the javascript implementation of the hashing algorithm: https://github.com/nimiq-network/core/blob/master/src/main/p... Chrome implements the WebCrypto API https://developer.mozilla.org/en-US/docs/Web/API/Web_Crypto_... I think it uses this interface: https://cs.chromium.org/chromium/src/third_party/WebKit/Sour...
