I have a fedora 7. My fedora 7 is running good. But my fedora 7 have one big problem. When i open firefox my fedora logging out. I tryng again... again, again. Open Firefox... Fedora is logging out. Please help me.

If you installed KDE desktop I would ask if konqueror web browser does the same, but because Fedora is set to install Gnome by default, you probably only have gnome. So I don't know if Gnome has a browser like KDE has konqueror to try and narrow down the problem. I customize my installations and un-check Gnome and install KDE instead. If you can't find a solution, it may be worth doing a new installation with KDE instead of Gnome to see if it might be Gnome related. (Not that I would like to point the finger at Gnome or anything). If you have both KDE and Gnome installed and Firefox logs you out of Gnome, does it log you out of KDE?.

EDIT: I would tend to think it is a network problem, does yum work?

You could try "elinks" open a terminal and just type elinks. You should get the text based browser up, you can go to any url but it doesn't load pictures.

I'm having this same problem (Fedora 7/KDE), and it only happens with firefox. I've run konqueror for days and days, but firefox is pretty much sure to log me out within an hour or two of starting it. It only logs me out when actively using it, like opening a new tab (or closing one) or things like that.

My firefox works fine on Gnome.
Did not face any problems yet!
In fact , replying to this post using the same browser.

And my FF on KDE also works fine, with no logouts.

Have you done a yum update to install all the latest updates? FF is currently at 2.0.0.4 on Fedora.

I ran updates this weekend, I'll run them again later this afternoon when I get home. I was using FF on Gnome, and had the same problem. (which is one of the reasons I switched to KDE - for Konqueror.) I'll install a non-FF mozilla-based browser and try that, too. More later.

What happens if you open a terminal windows and type "htmlview pai-nai.com" (without the ")?

If this command generate a error check if you have htmlview installed "yum search htmlview"

I've seen this happen when FF attempted to load an incompatible plugin, [e.g. java]. For example if you're loading the wrong version [or multiple versions] of java, FF will crash.
Check the link files listed in both the FF and mozilla plugins sub-directories. If it were my system I'd move the link files into a temporary sub-dir and try to load FF. If it works it's an issue with a plugin.
