Re: problem to load some page in firefox : "ssl_error_no_cypher_overlap"

I updated my systems to Firefox version 35 yesterday.

Firefox version 34 and newer have ssl3 disabled because it is a security risk.

If you attempt to connect to a web server that doesn't support tls 1.0 or higher you can't connect.

I have no problem connecting to tgui.eu with firefox.midori,or tazweb on 5.0/cooking

Ssl labs rates the server A,as it supports all tls versions and has vulnerable ssl disabled so I have no idea why you couldn't connect to it with firefox.

You can globally re-enable connecting to ssl by going into about:config

search for the preference named security.tls.version.min. double-click it, change its value to 0 and restart the browser.
