I've had it cause more problems with various Fedora versions that now I disable it.  I'm not running a server, just a one user desktop, so two firewalls (router and system) and being careful has kept me uninfected since Fedora Core 3.

Yes, it's a pain, but it will take less time than trying to find out what's currently the problem, and fixing it.  Just back up your data, etc. before doing it.

I tried all suggestions, firefox is still not load it appears as if try,
the "starting firefox ..." appears at the bottom of screen for few
seconds and then disappears. So it is time to do a full installation? I
will wait while just in case there may be some new idea to try.
Thanks to all of you.
