Problem with Firefox
 

Hi All,

I tried to surfing the internet onto Firefox, but it won't work at all. It say:

The proxy server is refusing connections

Firefox is configured to use a proxy server that is refusing connections.

I need your help to fixed the FireFox for me, please? I don't know what I doing. I would appreciate your help and please leave PM to me. Thanks Guys.

Go into your Firefox settings and ensure that Firefox is set not to use a proxy server. The correct setting will be something like "no proxy" or "direct connection to the Internet".

Also make sure you don't have any extensions that modify the proxy settings.

Problem with Firefox
 

I got it!! I just fix it. I did it all.

I am trying to get on Facebook by Firefox, but it does not have the entire page. Something is wrong.

Uninstall Firefox.

Go to https://www.mozilla.org/ using Internet Explorer and install a new Firefox download.

Also, I have a problem the Untrusted connections. It's say:

This Connection is Untrusted

You have asked Firefox to connect securely to download.mozilla.org, but we can't confirm that your connection is secure.

Normally, when you try to connect securely, sites will present trusted identification to prove that you are going to the right place. However, this site's identity can't be verified.

I am already on Firefox. Can you help me to fixed it for me?

Well Doc Savage's instruction is to first uninstall Firefox and use another browser to download Firefox again. With your proxy problem and now secure page access problem, you probably have some kind of malicious extensions running on your Firefox browser.

If you don't want to uninstall Firefox, try going into Firefox "Add-Ons" page to see check what kind of extensions are installed and disable them if you don't know what they are.

I would run a deep virus scan on your machine. Sounds like something is modifying/disrupting your internet settings. FF is warning you that your connection is compromised, which means the SSL handshake isn't working properly. Could be many reasons, but I'd bet you have a virus/worm/trojan/malware hijacking your settings.

One other super basic thing that always causes issues like this - are you sure the date and time are properly set on your computer? SSL certificates are only valid during certain dates, and if your system date is way off to the point that your computer thinks the SSL certificates are not currently valid, it will cause lots of problems and the internet will basically be unusable.

Because of the proxy messages, I agree with the others that it is also a good idea to run security scans on your computer also to make sure you don't have anything malicious running, either.

Yes, Scotty, go update your time settings first, then uninstall Firefox, run malware/virus scans, the try reinstalling a new Firefox download.

I'm not sure if uninstalling Firefox will clear the profile - if not, reinstalling will just bring the same problem back.

You can clear your profile by deleting (or renaming/moving, in case you want to recover it) the following two directories:
C:\Users\<your user name>\AppData\Local\Mozilla\Firefox\Profiles\<some long string of characters>.default
and
C:\Users\<your user name>\AppData\Roaming\Mozilla\Firefox\Profiles\<the same long string of characters>.default

(Path will be slightly different on XP, which I haven't used in enough years I can't remember exactly -- under "Documents and Settings" rather than Users?)

Firefox also has a "safe mode" which can sometimes be helpful:
