Disable Firefox Login Prompt

Issue: the customer configured firefox to automatically log into a site using the format http://user:pass@site.com.  Mozilla Firefox now prompts the user telling them "You are about to log in to the site".

Solution: After much searching, we discovered it is simply a missing value in the FireFox Config.

1. Open Firefox
2. type  about:config  in the address bar & hit enter
3. WARNING: modifying these settings could affect the installation/performance of FireFox
4. Right Click - New Integer
5. Name = network.http.phishy-userpass-length
6. Value = 100 (value options are 1-256, start at 100 and reduce to the length of your special URL)
7. Close & re-open FireFox & give it a try!
