Script Summary: Current version .9beta Add a random signature to your Gmail messages from a remote file.
This script uses code from several different scripts on the web. It works with Firefox 15 and 16 Beta. It grabs your signatures remotely from a file on a website. Just edit the three lines in the User Variable section of the script. Your signature file should be delimited by the % sign on a blank line. You can use any HTML code or plain text, just change the variable in the script to pick which one you would like (1 for plain, 2 for HTML). Please update the script for New or Old Look of Gmail using the two choices in the text. I will update to make this auto check eventually.
**Updated for Firefox 15 Final and 16 Beta
