Firefox web browser is not perfect indeed, and this is the reason why Firefox add-ons appear. As a loyal Firefox user who has been using it for several years, I meet an unexpected error occasionally. Some can be fixed with the help of Firefox add-ons but some cannot.

The “Firefox is already running” error message is the first annoying issue I have met. Today, I got a report of “This Connection is Untrusted” when I was loading Google SSL (HTTPS) search and other HTTPS websites. In the report, there is just a button that can “Get me out of here,” instead of showing me an option that lets me make an exception.

Well, how to get rid of this message in Firefox browser? If you are just looking to stop Firefox from displaying this warning notification and fix the issue permanently, here are several tips you can try:

1. Check the date and time of your computer system.
Wrong system time will trigger all the certificate errors. When the system date and time are incorrect, you may meet such a message everywhere. So to make sure the data and time are set correctly.

2. Prevent security products or firewalls from monitoring your traffic.
Most security products or firewalls may lead to the warning dialog. You see, when firewalls try to monitor the Internet traffic with a proxy, in the name of security, they will destroy the HTTPS links.

To get rid of this problem, they may want to install their own certificates, instead of the certificates from the web server. Firefox will show you the “This Connection is Untrusted Message” if such fake certificates cannot be installed successfully. One of the best solutions to get rid of this message is disable scanning SSL or other similar actions.

Now you can follow the steps mentioned above to resolve this issue. If the error still pops up in your Firefox after trying them out, just leave a comment below to let me know.

    So if I disable my anti-virus firewall scanning of SSL, Firefox will mind its own business and be just the browser – as it should be? But then I am increasing the vulnerability of my PC to attack, by disabling the anit-virus program I employed from doing its job? Why can’t Mozilla just mind its own business and let the anti-virus /firewall program do the same?
