This Connection is Untrusted
You have asked Firefox to connect
securely to techsoup.org, but we can't confirm that your connection is secure.
Normally, when you try to connect securely,
sites will present trusted identification to prove that you are
going to the right place. However, this site's identity can't be verified.
What Should I Do?
If you usually connect to
this site without problems, this error could mean that someone is
trying to impersonate the site, and you shouldn't continue.
Technical Details
techsoup.org uses an invalid security certificate.
The certificate is only valid for www.techsoup.org
(Error code: ssl_error_bad_cert_domain)
I Understand the Risks
If you understand what's going on, you
can tell Firefox to start trusting this site's identification.
Even if you trust the site, this error could mean that someone is
tampering with your connection.
Don't add an exception unless
you know there's a good reason why this site doesn't use trusted identification.
