The "invalid security certificate" errors are problems with the website you are visiting, not Firefox. The site is supposed to present a security certificate to demonstrate that it is safe and secure. If the site has no certificate, an unlocked lock appears at the bottom of the screen. If the site has a certificate, and it is valid, a locked lock will appear at the bottom. If the site has a security certificate, but it is wrong / outdated, then Firefox will warn you that someone might be trying to deceive you. You can bypass the message by clicking the "Add an exception" button, and then retrieving the certificate and viewing it.

I believe that these errors only occur under Firefox, so one alternative is to use a different browser. The only problem is that many web sites officially support only Internet Explorer and Firefox, and Internet Explorer has its own problems. You could use a third party browser, like Crazy Browser, and then open Firefox only when a web site tells you it requires Internet Explorer or Firefox.
