It looks like a lot of the slowness from the slow extensions is from parsing and executing JavaScript. Are there opportunities from the browser side to make extensions faster? It seems like re-parsing the same JS on every pageload is an opportunity for gains from caching, but I'm also wondering about different delivery mechanisms like wasm. Are there security considerations here?

Alternatively, heavy code could be kept in the background script while page-injected scripts only do interaction. This would even employ the JIT properly.
