Works! Rated 5 out of 5 stars
Not the most user-friendly of add-ons. Doesn't seem to do anything at first. You have to browse to www.pdfescape.com to open any PDF files either online or from your PC. But as an integrated cloud solution this is pretty decent with its tiny browser footprint.
Compare with Google Docs which relies on Adobe Reader for its advanced functions e.g. printing. PDFescape doesn't rely on Adobe at all.
Also consider Foxit Reader as a replacement standalone reader, but that is much bigger than PDFescape.
