cannot right click in Firefox

[Punkychan]

I have Firefox 1.5.0.7 installed and dunno what wrong had I done , now I can't right click and save image with it.I've tried with IE and it is working well..I assumed its not my mouse must be with the Firefox's settings...but could not find it.
Need help.

If you are at a page that does not have pictures in it that feature won't be seen. Some sites are also written for IE, with frontpage and such; the site may not be firefox compatible, so that could be a problem as well.
