I was going to edit my post, but now it is to late, ...
anyway, I shouldn't say "just a gimmick", the ssl certificates do have
a use full purpose, especially for commercial sites where on-line sales
are made, and also they could be applied even for sites that just
have a donation option,... the main thing they are good for is to help
prevent scammers setting up duplicate sites,or re-routing , and the victims think they are on the legit site, make a purchase, the money goes to the "fake site" , operator, and nothing gets delivered.
In other words , the certificate does help assure you are really connected
to the site you think you are.
by ticojohn » I think my question was more about why it is showing as not secure,
I am not sure on that, it seems like the Firefox people should make a effort to make it where the "site not secure " message is more clear, and
I do agree, this could have a negative effect on new users, or visitors,
that do not know better, Why does Firefox say a site is not secure
There are many results, here is one :https://support.mozilla.org/en-US/kb/what-does-your-connection-is-not-secure-mean
The only times I have gotten those kind of messages with Firefox were
on sites that have https, and either the certificate really was expired,
or in one case, it was because my clock/date on my computer was set
wrong, I was in the wrong year !,... so it actually had absolutely nothing
to do with the actual website being insecure,....
You really have not provided enough details to determine why it says
that, and is it just FDN, or do you get these messages on other sites as well ?
