Bug 1687764 is about implementing the entire MV3 API. Let's start small and focus on executScript() only with this bug:

One thing to maybe consider in the future, making target optional and defaulting to the active tab:

FYI relevant design docs from Chrome's side:

It seems that the documents are not accounting for non-serializable or non-callable functions. E.g.:

  • class X{} = cannot be called, only with new.
  • Math.min = function() { [native functon] } cannot be serialized.
  • new Proxy(function() {}, {}); = Proxy around function.
  • a = {async prop(){}, prop2() {}}; -> a.prop and a.prop2 cannot be called after trivial serialization ((async prop(){})() and (prop2(){})() are syntactically invalid)

The docs do account for cases where func.toString has been overridden with a custom implementation.
In practice, Xray vision in Firefox ensures that func.toString uses the native toString implementation, but it would be good to have unit tests nevertheless. Consider making that part of the initial patch, or a follow-up bug.

For scripting.executeScript(), we currently have a limitation around the world parameter. It only supports "ISOLATED", which is the default (see Bug 1759932). Adding support for other execution worlds is tracked in Bug 1736575.
