can't whitelist gmail, addon shuts ability to download attachment

Works as expected. Please be aware that it breaks the "Download as PDF" functionality in Google Docs for example. There is no error message, it silently fails. An exception list of URLs would be helpful.

good add on, just taking a star off because when this extension is enabled, it doesn't allow me to download PDFs from google (gmail, google docs, etc). I realised this after months of tinkering around so thought I should let you know. I did set this up as mentioned in the About.
