Approximately six months ago several web sites began to lose their styles gradually and finally some of them entirely stopped working in Opera although they work in other browsers. All this seemed to look like conspiracy against Opera-Presto.
Opera complains in Dragonfly:
No request made. All data was retrieved from cache without accessing the network.
As the certificates aren't updated automatically, I need to import them manually. But where to download up-to-date root certificates from?
- usr (x509)
- p7s (pkcs 7 signed)
- p7 (pkcs 7)
- p12 (pkcs #12 with security key)
Update - the real solution
In reality it wasn't anything wrong with Opera and it's certificates storage! The real bad guy was the Eset NOD 32 antivirus, which messed in some way with SSL connections, although it shouldn't. I understood it when almost all SSL web sites stopped working in any browser except Tor Browser. Turning NOD32 off didn't solve problem. I had to remove it completely and install it again.
What to do with an answer? Let it be here!
