periodically, i get this message in a popup window. since i never see a lock icon when entering personal data, i am concerned i do not have a secure connection. i have downloaded the latest firefox twice. "something is preventing firefox from updating securely. please make sure you have the latest version of firefox from www.firefox.com"

This issue can be caused by the presence of leftover files in the Firefox program folder (defaults\pref) like a file firefox.js that overrides the update URL with a wrong link.

See my post here and do a clean reinstall and be sure to remove the Firefox program folder.


In Firefox 4 you no longer have the Status bar that showed the padlock in previous Firefox versions.
The padlock only shows that there is a secure connection and doesn't guarantee that you are connected to the right server.
So you might still be connected to the wrong server if you make a typo in the URL and someone has claimed that mistyped URL.
The functionality of the padlock has been replaced by the How do I tell if my connection to a website is secure? on the left end of the location bar.
