I must have deleted the file y3.gif by mistake and now I can't open my Firefox browser. I have tried to recover it from my recycle bin but it's not there. Where can I go to download and reinstall the file?

I have Firefox installed but I don't find a y3.gif file anywhere on my hard drive. I suspect that it may be a file related to a plugin. I found a y3.gif file here (http://us.a1.yimg.com/us.yimg.com/i/ww/beta/y3.gif) but that doesn't mean it's the right one. Does Firefox give an error message? Maybe just reinstall Firefox.
