My ageing eMac is used almost exclusively for word processing and spreadsheets, however there are occasions when I try to connect to the net. I now get an error mesage which says

                               " Alert
               Firefox can't connect securely to start.mozilla.org
               bacause the site uses a security protocol which isn't enabled."

Can this be remedied or do I just throw my ageing iMac away?

The issue is that Firefox is caching security certificates rather than loading them fresh.

This doesn't become an issue until the cached security certificate expires, then the user faces the "this website is not secure" warning page. The user tries to reload the page multiple times and continues to get the same warning page, then they call me in a panic and say "my website is not loading because it is not secure!"

The solution is Ctrl+F5 and voila the website loads without issue.

However, this is definitely an "issue" and the issue isn't with the website or the lack of knowledge of the end user. End users should not need to know how to refresh their local cache of a website to resolve a security certificate expiring when it has already been renewed. Firefox should by default check for a new security certificate when the cached version has expired or at least that is what would appear to be the logical progression of local caching.

Unfortunately, I have been unable to find a way to report this issue to Firefox developers...so I am reporting it here in hopes that someone in the community has the ear of the development team and can point out this issue.

Thanks, Dr. Pat

I will give one example of many. In the past, I must have accidentally typed https://mail.wizathon.com. The correct URL is http://mail.wizathon.com. Now when I try to get to the http version, Firefox automatically switches it to https, which fails. To fix this, I have always gone to Options -> Privacy -> Clear Site Settings and poof, the http version would work. I have tried this, I have tried "forgetting the site", I have looked in my profile and the site isn't listed there, I have tried Refreshing my Firefox, I have gone into my about: config and updated the htsc to false. I am out of options. Something happened in the last 2 weeks to cause this unwanted behavior.

Locking duplicate thread.
Please continue here: [/questions/1091977]

When I search for something on Google using the search bar it says Untrusted Connection, and it doesn't let me "Understand the Risks" and go through. I'm able to get to Google.com but when I search for something it comes up glitched looking (Shows the old Google Logo, etc.) it doesn't let me use the features such as Images, News, Search tools. It automatically goes to Untrusted connection.

Also when I go to Google.com it says Not Secure Connection.

Hiya, I would appreciate help in finding the certificate I have downloaded from the FNMT website in Spain - it is to enable me to have a digital signature on the system in Spain and I have followed all their instructions - they say the certificate has been downloaded correctly. Trouble is, I can't find it! They tell me to open Firefox (it's already open), choose "Menú, Opciones, Avanzado, Certificados, Ver Certificados (Menu, Options, Advanced, Certificates, See Certificates). I cannot find where "Menú" is to start this series of choices - I've looked on Preferences and anywhere else I could to no avail. Could anyone help me, please? Many thanks, Anna

Microsoft just updated and now Firefox will not let me open up any web sites, except yours. It will not even let me open my Star One Credit Union account saying it is unsecured. I clicked the box that said exception and now it allows me to open this. However, there are still many sites it will not let me access without declaring an exception. I like the fact that Firefox will notify me of unsecured sites, but since it seems to think every site is improperly set up, how do I know which sites are ok and which are not?

I get a non-secure connection message back. It is quite strange since the https certificate is correctly installed.

Moreover, for your further information, I get this message while using Firefox on Mac, weheras everything is working correctly on Firefox for Windows.

Please find enclosed a print screen of the page cited above too.

I look forward to your feedback
