I set up a CentOS desktop computer for my brother and his kids. When Firefox 3.5 came out he decided to download and install it like he would Windows (he doesn't yet understand the repository system). He's been telling me that it works fine, even though I was skeptical due to my experience with Firefox 3.5 on CentOS 5.3. Then today, he says, "Oh, by the way, the CentOS computer has been rebooting itself every now and then." What?! (This is where he is in Linux -- doesn't realize that it's not like Windows, that it's not supposed to reboot randomly.) "Does it do it when you're in Firefox?" "Yes." He's okay, though, just a matter of uninstalling his home root version of Firefox -- I've been updating his computer with yum, so he still has the newest *repository* release of Firefox also. At any rate, just to let everyone know, whatever the issue is with Firefox 3.5 and *some* CentOS 5.3 computers (an Xorg graphics card incompatibility issue?) -- it goes beyond the RPM package released by Michael Harris. As for myself, I'm just going to wait for the repository Firefox 3.5 upgrade. -- RonB -- Using CentOS 5.3
