Firefox Won't Load Any Pages (Including Help Pages)
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.

I updated Rapport, but Firefox still wouldn't work. I disabled Rapport, but Firefox still wouldn't work.
I ran a System File Check. Corrupted files were reported and fixed. I did not have to reboot to safe mode to complete the System File Check.
Directly through my PC's Device Manager, the drivers for my Display Adapters (Intel HD Graphics 4600 and NVIDIA GeForce GTX 760 Ti OEM) were reported as being up to date. As for my current NVIDIA driver (according to NVIDIA update), the current version is 350.12. The newest available version is 364.72. I have not been able to update the driver to the newest version. In every attempt, I've been met with a black screen that is permanent until a total system reboot. I don't think this is the issue, as this is nothing new. Version 350.12 is very stable. I was able to try Windows Update to update the driver to a more recent version (not the current version, but one closer to it), but that failed. Windows Update noted that the current version was newer, even though NVIDIA update notes that it isn't (February 2015 versus August 2015).
So far, Firefox still doesn't work. I even tried disabling hardware acceleration, but that doesn't solve the problem. I'll update this thread if I'm somehow able to miraculously update my NVIDIA driver, but I'm doubtful that such a thing would work, or even be applicable to my current Firefox problem. It's also worth noting that I was able to install Google Chrome, and it runs fine. So far, Internet Explorer and Google Chrome both work fine, while Firefox doesn't.
hi, would you be willing to do some advanced troubleshooting on that machine for us to narrow down the range in firefox development when this error first occurred?
for that please download and install the "mozregression" tool from https://github.com/mozilla/mozregression/releases/download/gui-0.9.2/mozregression-gui.exe
- open the program from the start menu
- go to file > run a new bisection
- choose firefox/32/opt & click "next" two times
- as last known good date enter: "2015-12-02"
- afterwards the tool will download and open particular firefox versions - please test if it's working correctly in each version, close it & select "good" or "bad" in the tool based on the result
- this will run a couple of times & at the end the console window will show "the bisection is done" - please then click on the last tested build (in the bisection process pane), copy the result for the pushlog_url field as shown in the screenshot and paste it here into a reply on the forum.
thanks a lot!

you could disregard the former post about the mozregression tool.
however, would you be able to install this test build of firefox and give us feedback if the issue is still occurring there?: https://firstname.lastname@example.org/try-win32/firefox-46.0.1.en-US.win32.installer.exe
I didn't use the mozregression tool, but I did download the test build of Firefox (Nightly).
Nightly also does not work. It wouldn't load any pages, and I closed it normally. After a few seconds, the Mozilla Crash Reporter launched, much like it does for the standard version of Firefox.
thanks, could you share the new crash report that was generated then (maybe this can hold some clues) and try to use the mozregression tool as described above, since this may get vital results for developers understanding the issue before they can work on a fix.
Here's the latest crash info: Report ID Date Submitted bp-c1b7b7e5-70ed-4d93-8290-d4f9d2160430 4/30/2016 1:08 AM
I'll try to use the mozregression tool as soon as I can. Thank you.
I used the mozregression tool. Every build worked fine, but the tool never finished like you described. It just stalled. I'll include a screen shot of what it looked like, along with a copy of the pushlog_url field below.
Here's another image. I clicked on the last step before it stopped running.
I was able to run the mozregression tool to completion this time. Here's the push_log url. https://hg.mozilla.org/integration/fx-team/pushloghtml?fromchange=f82243c637f027297dfa2b79545aeeed34088d8d&tochange=b73dfc2916f959611cc90ee906678a5bf11a0b5f
I'll also include a screen shot of the finished program.
It's also worth mentioning that this is the third time that I've used the mozregression tool. The first time, I closed a Nightly (Firefox) window that opened, as you mentioned in your instructions. It wouldn't load any more windows after that, so I quit the program and started it again.
The second time was when the program stalled.
The third time, the program worked to completion. The build of Nightly (Firefox) that I closed the first time never came up as a test build in the future tests.
One more thing, the test builds that I marked as "bad" functioned to a degree. The two main Nightly web pages loaded fine. I marked them as such since the builds got stuck "looking up" websites in both instances.
thanks a lot, the results look rather inconclusive unfortunately since the pushlog points to a totally unrelated change, that had nothing to do with the network component in firefox. maybe the issue wasn't related to a particular change in firefox but due to some third-party signature update... can you try to uninstall trusteer report once as well & see if the regular firefox 46 (you can uninstall the test build again) behaves after a reboot?
I completely uninstalled Trusteer Rapport, rebooted my PC, and tried to launch the standard version of Firefox 46. Firefox still wouldn't connect to any web page.
Here's the most latest crash report: Report ID Date Submitted bp-0a303835-7ed8-4925-9a0c-071762160430 4/30/2016 1:33 PM
does anything change when you create a new firefox profile? Profile Manager - Create, remove, or switch Firefox profiles
When I tried the method to set up a new Firefox profile (firefox.exe -P), the only file it directed me to was attached to Nightly. I selected the file, and set up a new profile.
Under the new profile, I could view web pages, including the Nightly start up pages.
Interestingly enough, I was able to launch Firefox 46 standard after I closed Nightly, I'm guessing since it was tied to the new profile. It's worth mentioning that I was prompted to check the compatibility of add-ons (automatically, that is) with both Nightly and Firefox 46 standard before I was able to open them.
I closed Firefox 46 standard, and I used the profile set up tool again to restore the profile to the default option. I tried to launch Nightly from there, and it went back to not connecting to any web page. I closed Nightly, and here's my latest crash report: Report ID Date Submitted bp-befe26f8-7da4-430c-9e4d-f5fdd2160430 4/30/2016 1:58 PM
Just for the heck of it, I tried to launch Firefox 46 standard after that, and it also didn't connect, as expected.
thank you, does it make a difference when you manually clear the cache in your existing "default" profile? How to clear the Firefox cache
Clearing the cache was one of the first steps that I tried before I reported this issue. What's odd is that it gets stuck at "calculating web content cache size", and never gives an exact amount of space it takes up. Clicking on the "Clear Now" button, closing Options, and restarting Firefox 46 standard also changed nothing. I'll include a screen shot of what the screen looked like.
I also tried clearing the cache through the History option (time range to "Everything" for Cookies and Cache), but that changed nothing as well.
@thanks, i have another favor to ask since the developers working on fixing this issue need another piece of information.
could you create a log file of a session where you experience the connection issues like described at https://developer.mozilla.org/en-US/docs/Mozilla/Debugging/HTTP_logging ? contrary to the instructions in that link, the the exact commands we'd be looking for in this particular case would be:
cd c:\ set NSPR_LOG_MODULES=timestamp,sync,nsHttp:4,cache2:5 set NSPR_LOG_FILE=%TEMP%\log.txt cd "Program Files\Mozilla Firefox" .\firefox.exe
afterwards you could upload the contents of that log file to a site like pastebin.mozilla.org and share the link with us. if anything is unclear in these instructions please don't hesitate to ask... thank you!
