What's the fingerprint of the certificate you're getting from google.com? I get:
SHA1: 3c6bde6ca0a1ae6ae9d5bfb367ab124e1b988bfb
MD5: 2791dac0733085dbe323ef7d6faa7fcd
Well it doesn't always give the warning. Only sometimes. I randomly searched things until it appeared and then got the fingerprints. After writing them down I compared them to a situation when it is not giving the warnings and they matched. But here they are anyway. I'm sure they are probably right.
SHA1 Fingerprint: D8:06:3D:AA:BB:9A:37:21:FE:95:DD:AC:DE:64:2F:20:17:57:FE:DF
MD5 Fingerprint: E8:1D:A1:DD:10:93:F5:24:23:F1:5A:81:39:DA:41:F8
