Whenever I open Firefox, in any Web site, including the site of Firefox settings, an announcement I have to see it, and when I try to stop it, said ARE YOU SURE?

Ok. Then when I open Firefox, I go to my home page. Then when I click on the button Search (before entering), it brings me to a different window of an advertisement. I tried advertising blocker, but there is absolutely nothing to prevent it from opening. On each page, when I click on anything, whether it's up a different window of an advertisement. Now, my other problem is, when I play a video on YouTube, Firefox is not responding. But then the video plays normally. In this case as, EVERY single video I watch it on Firefox. Solve the problem.
And also, Shockwave Flash keeps "no answer / busy" almost on every page that I opened. other than YouTube and all related "google" pages

Hi, sometimes a problem with Firefox can be a result of malware installed on your computer.

You can try these free programs to search for malicious software that work with your existing anti-virus software:

Microsoft Security Essentials is a good permanent antivirus for Windows 7/Vista/XP, if you do not already have one. Windows 8 already has integrated antivirus.

More information can be found in the article troubleshooting Firefox problems caused by malware .

You must also update your Shockwave Flash Player (Ctrl + Shift + A > Plugins)

This solve your problems? Please report to us!
