For Firefox --

In the Location bar, type about:config and press Enter.
The about:config "This might void your warranty!" warning page may appear. Click I'll be careful, I promise! to continue to the about:config page.
Type security.enable in the Search field.
If both security.enable_ssl3 and security.enable_tls are set to true, skip to the next section.
If both security.enable_ssl3 and security.enable_tls are set to false, double-click each of them to set it to true.
Try to access a secure site again.

For Chrome --

Step 1:
Click "Customize and Control Google Chrome" menu.
Step 2:
Click "Options" button.
Step 3:
Under "Google Chrome Options" window select 'Under the Hood" tab.
Step 4:
"Under the Hood" tab go to "Security" section.
Select Trusted SSL Certificates
Step 5:
Click "Manage certificates" button.
Step 6:
In the "Certificates" window you can Import, Export and Remove your SSL certificates.
Step 7:
To setup computer-wide SSL settings follow this step.
'Use SSL 2.0': This is an older version of the SSL protocol that is less secure. However, some websites may require visitors to use this version when browsing. If so, select this option only if you trust the website.
'Check for server certification revocation': Turn on real-time verification for the validity of a website's certificate, for extra security. A certificate can be revoked by its third-party issuer if it detects that the certificate has been compromised or stolen.
