Mozilla web pages are white with black\blue text & netflix doesn't work Win10
Firefox use to work fine but now its not (currently version 39) At first i noticed netflix was producing a error once i tried to start playing a video but after I uninstall firefox and delete all profiles it doesnt even let me visit the web page giving this error
Secure Connection Failed An error occurred during a connection to www.netflix.com. Peer's certificate has an invalid signature. (Error code: sec_error_bad_signature) The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
The other problem i noticed was that some web pages do not display correctly like the Mozilla forums is just a white background with blue and white text
I have tried nightly 64bit portable same problem Crome\Explorer work fine
Thanks

The difference between Firefox and IE/Chrome is that IE/Chrome share the Windows certificate store. Firefox has its own certificate store. (Which you deleted by deleting your profile.)
This error can be caused by a range of issues, but typically the certificates are generated by an intermediary such as a proxy server, your security software, or malware. Let's investigate which one it is.
Q: Do you use Avast, ESET, Kaspersky or BitDefender, or browse through a proxy?
If you have sites where you have created a security exception, such as this site, check the certificate for more information on its issuer. You can click the padlock (or gray warning triangle) in the address bar, then More Information, then View Certificate. The areas to check are "Issued by" and "Certificate Hierarchy." I have attached a screen shot for this site as an example. If you can't view it in Firefox, you could use Chrome. I've attached that example, too.
What do you see?
Note: Firefox's support for Windows 10 will be more complete in version 40 which, if you are an early adopter, you could try in beta. I don't recommend Nightly. https://www.mozilla.org/firefox/beta

Ok it looks like avast free web shield was the problem Thanks
Tried 40.0b6 then but it made the system stutter badly while trying to play netflix where as 39 works fine If only chrome\Firefox allowed for above 3000 bit rate like edge
