For those of you who update to latest releases of Mozilla Firefox,


Mozilla

chances are high that you have run into ssl_error_no_cypher_overlap or similar errors. It might be a bad idea to ignore errors like these on websites which are public and you are not sure of. But in case you start getting this error for sites you have been routinely accessing before updating you can bring down the min tls version.

Here is how you can work around this issue

1. Open a new tab in Firefox and type “about:config” in the URL bar

2. You would get a warning dialog box, click Promise to be careful and move on

3. In the search bar, enter the following security.tls.version

4. First, right-click on the setting “security.tls.version.fallback-limit” and select modify.  You’re going to change the “1” to “0”.  Then do the same thing with “security.tls.version.min”, changing the “1” to “0”.
