As of Tuesday, April 16 Firefox Nightly no longer allows a user to type into a Google Doc (i.e. Document created within google drive). After updating 23.0a1 (2013-04-17) the problem is still present. This has been verified across multiple google docs (to ensure it wasn't a permission issue with google docs) and also 2 Firefox instances (to ensure it wasn't my profile). This is not a problem with google docs, everything works fine in my Firefox aurora instance. Steps to reproduce: Go to google drive and create a new document Try and type into the document, it won't work
