Review: OK - script works, but has bugs

Works fine, although I encountered a QuotaExceededError: The operation failed because it would cause the application to exceed its storage quota. error when trying to download something. I got around that issue by launching my chromium with the flag --unlimited-storage but then GM_download failed due to some url not being whitelisted, so I modified triggerDownload to have an optional last argument that allows it to fall back to using anchor tags for the download if GM_download fails for whatever reason and now it works as expected. Perhaps that is something that could be added to the script.
