This is merely a notification meant for the website administrator that they should update their server software and this shouldn't affect the functionality. If there are problems then something else is wrong.

"Remove Cookies" from sites causing problems:

  • Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"

Start Firefox in Safe Mode to check if one of the extensions (Firefox menu button/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

http://gefest.rads-doi.org/index.php/login I got to the login page with no problem.

This site uses the SHA-1 certificate; use certificates with the signature algorithm, using a stronger hash than the SHA-1. [More]

With the newest Firefox, some Security Certificates have been disabled because of issues with new mal-ware. Can you check with the site on what Security Certificates they are using? (SSL and TSL encryption protocols)
