Sometime this March, the Firefox, Chrome, Safari and Edge browsers will start throwing up warnings when users visit websites that only support Transport Layer Security (TLS) versions 1.0 or 1.1.

Shared components used by Firefox and other Mozilla software, including handling of Web content; Gecko, HTML, CSS, layout, DOM, scripts, images, networking, etc. Issues with web page layout probably go here, while Firefox user interface issues belong in the Firefox product. Not all browser related errors are associated with SSL Certificates. Many are due to server configurations that set up communication between the website/server to the clients browser. Different browsers will showcase errors differently. But ultimately the troubleshooting process regarding these errors are the same. What is a Protocol or a Cipher? Protocols and Cipher Suites are the actual. supports only TLS version 1.0, which is now broken (or at least weakened) and way obsolete. According to its headers it is Apache 2.2.15 (Fedora) which dates from 2010! This therefore appears to be the same problem as OpenSSL v1.1.1 sslchooseclientversion unsupported protocol except Ubuntu instead of Debian and wget (used by octool) instead of openvpn. Error code: SSLERRORUNSUPPORTEDVERSION The security protocol it refers to is TLS. There are three problems, however, with this Firefox error message. For one thing, TLS 1.0 and 1.1, which the.

Announced in October 2018 as part of a joint plan to phase out support, the implications for any holdout sites are stark – enable the later TLS 1.2 or, ideally, 1.3, or face having no traffic.

According to the latest Mozilla reminder, visitors using Firefox will start seeing a ‘Secure Connection Failed’ message with accompanying SSL_ERROR_UNSUPPORTED_VERSION for anyone in doubt.

Initially, it will be possible to override this but only for so long. Sooner rather than later, Mozilla says that too will disappear:

We’re committed to completely eradicating weak versions of TLS because at Mozilla we believe that user security should not be treated as optional.

Other browsers will follow suit, with the Chrome browser having adopted ‘Your connection to this site is not fully secure’ messages last month with full blocking due to begin in March.

But why the need to ditch TLS 1.0 and 1.1?

Although not exactly a household name, TLS is the encryption protocol that makes several types of secure connection possible, including secure versions of SMTP, POP3, FTP and of, course, HTTP.

For example, when a browser visits a site using HTTPS, TLS sets up authentication, the exchange of session keys, and agreement on cipher suites.

To make all this work, both ends must also agree which version of TLS they will use, which is where the problems start for older versions.

Issue number one is the age of TLS 1.0 and 1.1.

As far as the IETF is concerned, TLS 1.0 has been around since 1999, building on technology invented years before that to work with Netscape’s famous but ancient Navigator browser.

TLS 1.1 arrived in 2006 but was quickly improved upon by TLS 1.2 two years later. We’re now up to TLS 1.3, support for which is appearing now.

Going from TLS 1.0 to 1.3 might not sound like a huge jump but TLS 1.3 is vastly more secure and more optimised for the speed of today’s internet – both valid reasons to ask sites to get rid of older versions.

It’s not clear how many sites still use TLS 1.0 and 1.1 – Google estimates around 0.75% of page loads – but even a small sliver of sites is now too many.

Judging from the sites cited by Google, most appear to be smaller domains which are either unmanaged or managed passively.

From March, for the want of an upgrade, these sites will start to suffer the consequences of that.

Error Code: Ssl_error_unsupported_version

Starting about a week ago, several sites/pages that I've previously visited successfully will no longer load. Most notably, I can no longer get Amazon's 'My Cart' page to load. Instead, I get the following message:

Well, I'm not likely to get much attention from Amazon, and the smaller sites are as confused about this as I am.

I've already tried the 'no proxy' setting in FF (no joy) and renaming cert8.db and deleting cert_override.txt (also no joy).

My next test is to disable all of the extensions that I've installed in the past month (but I have to restart, so this post comes first--I'll report back in a reply).
