If my network connection goes out briefly due to a problem at my ISP, FireFox immediately opens a "diagnose network problems" page. This is particularly annoying when I don't even have FireFox or any other software open. Ideally, I do NOT want FireFox to even check if my Network is connected. How can I stop this?

I'm not sure which page you're referring to.

In order to better assist you with your issue please provide us with a screenshot. If you need help to create a screenshot, please see How do I create a screenshot of my problem?

Once you've done this, attach the saved screenshot file to your forum post by clicking the Browse... button below the Post your reply box. This will help us to visualize the problem.

Thank you!

I can find no method to duplicate this issue manually. It only happens when my ISP connection goes out such as during a power outage at the providers source.

But I believe the root to my problem can be resolved if FireFox, when it is not even running, does not even attempt to connect to the internet when my network connection is lost. No other browser I have used does that, i.e., Internet Explorer or Google Chrome.

Thus my last question needs to be answered. Is there a way to stop FireFox from even searching for an internet connection when FireFox is not even running?

I've never heard of Firefox doing what you're describing, which is why a screenshot would be helpful. I'm guessing there is an add-on or plugin which is causing this behavior.

Attaching print screen of currently installed extensions and plugins.

That message is probably from the Operating System, not from Firefox. Firefox can't provide messages if it isn't even running.

Agreed. Check your Windows Network and other settings.

One last thing. the current Firefox is v37.0.2

I am not saying you are wrong, but I have grave doubts that is the case because the message opens up in FireFox. Every other similar message from the operating system has it's own specific Windows generated dialog box. Furthermore, the message does not appear if FireFox is not installed at all or another browser is set as my default browser.

Regardless, I guess my best bet is to wait for the next time this message pops up and then capture a screen print to submit showing exactly what happens.

I sincerely appreciate all of your responses.

Firefox? That is very strange. Can you post a list of your add-ons?

I'm willing to bet this is being caused by Avast. It could be the download manager add-on though. I would disable them, and then restart Firefox, one at a time to see if the problem goes away.
