Hi kamranh, I'd try starting Firefox in [[Safe Mode]]. If you don't have the issue while all of your add-ons, extensions, and themes are disabled, you can try adding them back in one by one until you find the culprit. You should look at the [https://support.mozilla.org/en-US/kb/Troubleshooting-extensions-themes Extensions and Themes troubleshooting guide ] and the [[Troubleshooting plugins]] article as well. From the looks of it though, your issue may be because you've been hit with some [https://support.mozilla.org/en-US/kb/Is%20my%20Firefox%20problem%20a%20result%20of%20malware?s=malware&r=0&e=sph&as=s#w_how-do-i-get-rid-of-malware Malware]. If isn't malware or a plugin issue, you should take a look at the Knowledge Base article [[Search bar]]. Your default search might have been changed by a particular site. Sites like MSN, Yahoo, etc have been know to ask to become your homepage and change your search engine. If the address bar search has been changed as well, you might want to take a look at [[Location bar search]]. If that doesn't work you should look at the article [[Preferences are not saved]]. Hopefully this helps!
