I am using the latest Firefox browser with our Add-on, Blur – version 52.0 (64-bit). It is reporting a security warning when I attempt to enter my password.
The message is this:
This connection is not secure. Logins entered here could be compromised. A lock icon is also displayed with a red slash across it.
Is this really a security problem or has Firefox got it wrong?
We noticed that we don’t get the error in nightly build version 53. We think it’s because we use our own protocol (blur://) to talk to our background script which then uses https to communicate securely.
Thanks in advance for any insight!
