To Reset Firefox do the following:
Further information can be found in the Refresh Firefox - reset add-ons and settings article.

This can happen if you have an ad-blocking extension or (security) software that is modifying the HTTP headers and removes GET data (?xxx=xxx) appended to a link to request a specific (ad) file from a server.
Start Firefox in Safe Mode to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).
Which security software (firewall, anti-virus) do you have?
Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.
Do a malware check with some malware scanning programs on the Windows computer.
You need to scan with all programs because each program detects different malware.
Make sure that you update each program to get the latest version of their databases before doing a scan.
You can also do a check for a rootkit infection with TDSSKiller.
