Curiously, Chrome doesn't support extensions in headless mode. And Browsh needs to run some custom CSS and JS to help with parsing, so Chrome was a no go. You can inject CSS and JS using the RPC though, but that RPC standard (https://remotedebug.org/ https://remotedebug.org/) isn't yet supported by Firefox. So at the time I felt that using the webextension standard was a more cross-browser investment. Perhaps I should revisit that decision. And yes you're right about the use of a remote server to make use of the bandwidth savings.
