Answer 1

It sounds like your computer may be infected with some sort of a virus / Malware.
I suggest the following resources:
[[Is my Firefox problem a result of malware |Is my Firefox problem a Result of Malware]] is a Mozilla Support article with some good tips on avoiding and fighting malware.
To double check your system is clean, do the following (Not official Mozilla advice, just good practice from personal experience)
Download and Install MalwareBytes Anti-Malware, run a full Scan. [http://www.malwarebytes.org/ http://www.malwarebytes.org/]
Download and Run TDSSKiller [http://support.kaspersky.com/faq/?qid=208283363 http://support.kaspersky.com/faq/?qid=208283363]
Download and Install Microsoft Security Essentials [http://windows.microsoft.com/en-US/windows/products/security-essentials http://windows.microsoft.com/en-US/windows/products/security-essentials] (not an official endorsement, but I personally recommend MSE as an awesome permanent anti-virus)
Double check for all Windows Updates.
If you are still having problems with Malware after that, I would recommend either [http://www.bleepingcomputer.com/virus-removal/ http://www.bleepingcomputer.com/virus-removal/], or having your computer cleaned by a professional.
After removing the virus, read [[Websites look wrong|Websites look wrong]] and see if that helps you.
