There is a chance that you have an improper architecture of Firefox i.e if your system is a 64bit processor, you might have a 32bit Firefox. Please check the above and try reinstalling Firefox and let me know!

Thank You! :)

Thanks a lot! I have been stressing a lot about this. I have been using Firefox like forever.. I don't want to change my browser. It's true that I just download Firefox without considering the system processor. Will keep that in mind. Thanks again!
