No problems here.

Note that the portal3.univpm.it server needs to update their server software as they only support older cipher suites and connect by default with one of these suites: "portal3.univpm.it:4445: Connection Encrypted: High-grade Encryption (SSL_RSA_WITH_RC4_128_MD5, 128 bit keys)" "portal3.univpm.it:4445: Connection Encrypted: High-grade Encryption (SSL_RSA_WITH_3DES_EDE_CBC_SHA, 112 bit keys)"

• security.ssl3.rsa_rc4_128_md5 = true
• security.ssl3.rsa_des_ede3_sha = true

Do these CSS files load if you check that in the Inspector (Firefox/Tools > Web Developer;Ctrl+Shift+I) or on the Network tab?

Thank for the info about encryption could it be related?

Like the main page, the CSS file sometimes are loaded and some aren't.

The error I get is "The connection was reset" reloading the page many times I can see the page.

This is what i get first time I try to load the page: http://193.205.135.144/Not_Loading.PNG

And after some retries: http://193.205.135.144/Loading.PNG

This does not happen with older Firefox versions or other browsers.

Thanks again for your help.

I get "The connection was reset" when I disable the two cipher suites that I mentioned above.

You can check the ssl and tls prefs on the about:config page. If any ssl or tls pref is bold (user set) then right-click that pref and choose "Reset" to reset the pref to the default value.

Paste this regular expression in the Search bar at the top of the about:config page:

• /security.*ssl|security.*tls/

(you can open the about:config page via the location bar)

I've checked but all the options are default (I've also tried with a fresh portable version), beside the problem is not only on my Firefox, we are getting tens of calls from people saying they cannot access that server anymore after they upgraded from Firefox 26 to 27.

Do direct links that I posted above not work as well?

Try to rename the cert8.db file in the Firefox profile folder to cert8.db.old or delete the cert8.db file to remove intermediate certificates that Firefox has stored.

If that helped to solve the problem then you can remove the renamed cert8.db.old file.
Otherwise you can rename (or copy) the cert8.db.old file to cert8.db to restore the previous intermediate certificates.
Firefox will automatically store intermediate certificates when you visit websites that send such a certificate.

If that didn't help then remove or rename secmod.db (secmod.db.old) as well.

With the css links I have the same exact behavior (reloading the page many times I have some times 'The connection was reset' and others the page loads). This is a video of what happens: http://193.205.135.144/firefox27.mp4

I tried to rename cert8.db and secmod.db but with no effect.
