I am unable to get to add-on in firefox version 28.0 ""This Connection is Untrusted

You have asked Firefox to connect securely to services.addons.mozilla.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.

Can't you go to https://addons.mozilla.org/ ?

Are you using an extension like HTTPS Everywhere that forces a secure connection?


You can remove all data stored in Firefox from a specific domain via "Forget About This Site" in the right-click context menu of an history entry ("History > Show All History" or "View > Sidebar > History") or via the about:permissions page.

Using "Forget About This Site" will remove all data stored in Firefox from that domain like bookmarks, cookies, passwords, cache, history, and exceptions, so be cautious and if you have a password or other data from that domain that you do not want to lose then make sure to backup this data or make a note.

You can't recover from this 'forget' unless you have a backup of the involved files.

It doesn't have any lasting effect, so if you revisit such a 'forgotten' website then data from that website will be saved once again.

I am able to get addons by going to addons.mozilla.org. There is no "services." prefix before that address. I also have not seen that error message while getting addons.

When do you get this error message?

Are you using a bookmark or the "Firefox/Tools > Add-ons > Get Add-ons" window or otherwise?
