Can this code be made to work with Orion Browser?

Would it be possible to revive this extension in order to work with the upcoming Orion Browser for macOS?

Or is this code not compatible with the current Browser APIs?

It was designed exclusively for the Safari extensions API that existed at the time. It will never function in any newer browser, sorry.
