Firefox ban on SHA-1 certs causing some security issues, Mozilla warns
Mozilla has warned Firefox users that its decision to reject SHA-1 certificates has caused an unfortunate side effect: some man-in-the-middle devices, such as security scanners and antivirus products, are failing to connect to HTTPS sites.
The browser maker advised any netizens affected by the interference to install the latest version of Firefox, which reinstates support for SHA-1.
Indeed, ’tis the season for browser upgrades. As Ars reported on Tuesday, Microsoft has been furiously nudging Internet Explorer holdouts over to the latest versions of its browser.
