Tired of Firefox trying to protect you from yourself? You can turn off the irritating warning.
Mozilla (along with other browser providers) wants to protect you from websites that aren’t using SSL. Starting in Firefox version 52, you see a warning message when you click inside the login box to enter a username or password.
There is a hidden preference to this off.
How to Turn Off Firefox Insecure Password Warning
- In a new tab in Firefox, type or paste about:config in the address bar and press Enter/Return. Click the button promising to be careful.
- In the search box above the list, type or paste the text: insec
- Locate the security.insecure_field_warning.contextual.enabled preference and switch the value from true to false
You do this at your own risk. It is easier to steal password information from an insecure site than a secure site. That said – every security system can be hacked, and https: aka SSL implementations have been hacked before.
