Mozilla blames ‘interlocking complex systems’ and confusion for Firefox’s May add-on outage
Mozilla has issued multiple after-action reports analyzing the major mix-up in May that crippled most Firefox add-ons. The reports also made recommendations for preventing similar incidents in the future.
The fiasco started just after 8 p.m. ET on Friday, May 3, when a certificate used to digitally sign Firefox extensions expired. Because Mozilla had neglected to renew the certificate, Firefox assumed add-ons could not be trusted – that they were potentially malicious – and disabled any already installed. Add-ons could not be added to the browser for the same reason.
