I'm with you. It's obnoxious to have to disable a long list of things with every install, but if Firefox didn't support something everyone else does they risk driving people who want that functionality away. I don't mind the bloat as long as it's easily disabled and they go out their way to notify users of the risks when they don't have it disabled by default.

I want firefox to keep giving people the option to do whatever they want, I just don't want them forcing anything on people, making them more vulnerable by default, or not being clear about things they've added support for.

How is wasm worse than JS?
