Windows 8.1 64-bit Firefox 35 (Latest)

- Fresh Installed firefox 35 - Even refreshed Firefox with safe-mode - when opening page google.com, facebook.com (Attached Image) getting error page that should not be the error/exception. - This is not for the first time even in past I had got this error for google.

Why firefox developer is neglecting this every time they introduce newer version.?

reinstalling probably won't work. this problem looks like it is being caused by MS family safety filter and Windows Update KB2965142 (published on 6/9/2014) in particular. in order to resolve it, please refer to Microsoft's documentation on the subject: http://support.microsoft.com/kb/2965142/en-us#2

hello raviparekh027, thanks for providing the screenshots.

as this problem might have different external causes please provide another piece of information: when you attempt to add an exception on the bottom of the error page (don't do it for real though!) & inspect the certificate, which issuer information does the certificate contain? (see screenshot)

thank you!
