Problem description: I can type an address into the URL bar, but when I hit enter, nothing happens. Nothing happens when I hit the "go" arrow. Nothing happens when I paste an address into the URL bar with "Paste & Go". The awesome bar functionality seems to work, but when I select an address, it puts the address in the URL bar, but nothing happens. It's just refusing to actually load any URL I type into the URL bar. The bookmarks menu works just fine, as does everything else. This occurred when I upgraded to Firefox 20.0. I found the problem, but I'm not sure if this is a bug or not. I tried disabling all the add-ons, but that didn't help. The problem did NOT occur when using a fresh newly-created profile. You're probably thinking something was corrupt in my old profile. But that's not it. The problem occurs when the profile is located on a network share. If I copy the profile to the local hard drive, the problem goes away. If I copy the fresh new profile to the network share, the problem starts occurring there. I keep the profile on the network share because it gets backed up automatically every night. I have been doing this for at least the last five or six years, and it's been working fine since I don't know what Firefox version. 4 or 5? No idea, not important. Here is my profiles.ini: --------------------------------------------------- [General] StartWithLastProfile=1 [Profile0] Name=Joe D IsRelative=0 Path=\\Splut\joed\.mozilla\firefox-win\Profiles\7ng20p6c.default [Profile1] Name=Copy IsRelative=1 Path=Profiles/7ng20p6c.default Default=1 --------------------------------------------------- As you can see, profile 0 is on the network share, and profile 1 is on the local hard drive. I copied the profile from the network to the local drive to create profile 1. But wait! It gets even better! They are not just identical copies. They are the EXACT SAME FILES. The folder for profile 1 is a symbolic link to the folder for profile 0. (Yes, you can do symlinks in Windows now.) So the profiles are literally exactly the same, but one works and the other doesn't. This solves my issue by allowing me to keep my profile on the network, but the other way should still work. Any ideas?
