Gives error after running whole thing to the end.

The extension itself might work good but there are a couple of things which are not ok. 1) "Give Feedback" leads to 404 for me using v2.1.6. 2) "Page Weight" leads to different results of the identical page 3) The extension cannot be used in batch mode or via an external tool It would be nice to have the (regularly updated) list of rules which the extension checks when running.

The add-on is no longer working with Edge or Chrome. Does not recognize site type.
