Greasemonkey is a great addon but its main drawback is that its not possible to read/write files from hard disk. So, is there any other addon that can read/write files from hard disk??
回答1:
Chickenfoot might well work for you, and it does do file IO.
Or if you feel particularly frisky, you could fork off of the Greasemonkey code and make a version that bypasses the file restrictions.
