Why cannot start mozilla firefox  but i start internet explorer

I surf regularly website. But since one week I cannot reach it using my Firefox.

It never happens like this. It shows a message like "The connection was reset.". 

Please solve this quickly.

A message secure connection failed is shown always on my desktop when I go to connect the web browser Mozilla Firefox. It comes always and cannot do any work without deleting it.

Sometimes network cannot do any work by Mozilla Firefox. Then it is necessary to restart the computer. What should I do?

The image is shown below:

The internet is connected, its working fine in another home group computer. But in my computer it says website not found. Even in my computer the antivirus is updating it self . That means the computer is connected but why i cannot browsing?

Recently I have installed windows 7 and the latest version of Mozilla Firefox on my PC. I am used to open multiple applications when i am surfing using my Firefox browser but ever since i have installed Firefox i am getting an error of excess memory being used. Sometimes 230MB and sometimes 440 MB like this.

How can i fix this problem so that i don't get the error?

I Have set Mozilla to accept updates whenever one is available. I have no problem with that.

However,  just recently, it seems that there are some updates whose automatic installations are refused and gave the error about malformed XML File.

Please refer to the image of the error included here. Please advise what to do to solve this problem. Thank you.

There were problems checking for, downloading or installing this update. Firefox could not be updated because:

AUS: Update XML File Malformed (200)

Please tell me why Mozilla Firefox is better Than any other Browser. Where as Google Chrome is the most unique Browser but most IT experts prefer to use Mozilla Firefox.

Hi to all of you!

Last night, when I used Mozilla Firefox to open a site that starts with (https), then an error occurred. So, I decided to just open it this morning, but the same thing happened. I checked if it will also appear in the Internet Explorer, and it did not.

My question now is, is it a Mozilla issue or is it just a local browser issue? How can I get rid of this?

Here is the error:

Mozilla Firefox Error:

Unable to verify the identity of winqual.microsoft.com as a trusted site

Possible reasons for this error:

Your browser doesn’t recognize the certificate authority that issue the site certificate

The site’s certificate is incomplete due to a server misconfiguratiion
