Is Google Docs Viewer safe?

Clean risk

Google Docs Viewer redirects configured Office-document downloads through Google Docs Viewer with the document URL attached.

When a supported document type is enabled, the extension watches browser responses for matching Office-style files and redirects those loads to Google Docs Viewer. The original document URL is added to the Google Docs Viewer request so Google can fetch and display the file.
