Given the behaviour of apps, I think I will use only websites from now on.
Does Firefox have a fine grained way to kill these scripts, or is disabling JavaScript for all websites the only option ?
You can disable JS per site with an add-on. For example, uBlock origin works on mobile Firefox on Android, and you can use it disable JavaScript on any domain you want without impacting others.
Will expanding collapsed comments still work with JavaScript disabled ? What about commenting and voting ?
