After more than six months of constant problems with antivirus software meddling with Firefox’s configuration and certificate store only to crash HTTPS websites, Mozilla announced today a final solution for this long-pressing issue.
According to Mozilla Certificate Authority Program Manager Wayne Thayer, starting with Firefox 68, the browser will automatically enable an about:config preference that will make it less likely that antivirus software crashes an HTTPS page.
The preference is “security.enterprise_roots.enabled”, which starting with Firefox 68, the browser will set to true if it detects a “Man-in-the-Middle” TLS error, which is the typical error specific to antivirus software trying (and failing) to intercept a connection to an HTTPS website.
