On the evening of April 28th, I attempted to open Firefox, and it notified me that it was updating itself. Once the update was complete, I was able to launch it. I did notice that it had some minor issues (getting stuck "looking up" web pages, even when other browsers worked fine), but those same issues had occurred before.
My current problem is that Firefox will not load ANY pages, including any Mozilla help pages. This first started happening after I used Windows Update to upgrade the .NET Framework to version 4.6.1 (KB3102433). After my system restarted, I noticed that Firefox couldn't connect to any website (doesn't even say "looking up" or "connecting" in the bottom right hand corner of the screen, just tries to connect indefinitely), and that my antivirus program (McAfee LiveSafe) couldn't connect to the internet for automatic updates. Other programs such as Steam and Internet Explorer had no issues.
My first step to try and fix this was to roll my system back to the restore point just before I upgraded to .NET Framework 4.6.1. My system went back to .NET Framework 4.5.2. This did not fix the problem. Firefox and McAfee LiveSafe still couldn't connect to the internet. I also tried modifying my connection settings in Firefox. It was already set to auto detect proxy settings, which matched Internet Explorer's settings, so I made no changes. I tried uninstalling and reinstalling Firefox, but that didn't work. Oddly enough, this DID work for McAfee LiveSafe. After I reinstalled LiveSafe, it was able to connect to the internet.
I've tried starting Firefox in Safe Mode, as well as refreshing it. The problem persists. Firefox isn't being blocked by a firewall (checked Windows Firewall and McAfee's firewall). I even tried turning off all firewalls to see if Firefox would work. It still doesn't work. I haven't downloaded any new add-ons for Firefox recently, other than an add on from McAfee LiveSafe that was added on after Firefox started having problems (when I had to reinstall LiveSafe). I'm at a loss as to what exactly is causing this issue with Firefox, and what further steps I need to take to fix it.
It's worth noting that every time I have to close Firefox (after seeing if it will function correctly), the Mozilla Crash Reporter pops up after a short period. It's odd that it pops up, since I close Firefox normally each time I need to. The Mozilla Crash Reporter has successfully sent the crash report every time, which is interesting. I'm not sure how the actual browser doesn't work, but the crash reporter can connect with no issues.
Any assistance would be greatly appreciated.
