Contact support missing for Anti Certificate Spoofing Firefox add-on
Hi to Mozilla support community,
I have found an interesting Firefox add-on offering Anti-spoofing protection by checking website certificate at the first visit, and then later.
Here is the page: https://addons.mozilla.org/en-US/firefox/addon/anti-certificate-spoofing/
Having tried to contact the support to ask some questions, it occurs the support email address is not valid (the domain doesn't exist).
On the add-on store, there is only a report button for abuse, but it's not the case here.
Can anyone help to get in touch with the support for this add-on or what to do in such situation?
Many thanks,
Alex
