Firefox Community Forum

For over a year, my browser occasionally loses connectivity. It may work for 3 hours or 3 days, but inevitably new tabs will stop working and then slowly the others will stop as well. When this happens, none of my other browsers are impacted. They work fine. It is only Firefox. The only solution is to close everything and lose all my work.

Once I do that and restart Firefox, I receive an error message telling me I am using an older version of Firefox that is not compatible with my profile. The only solution that brings me back to the best starting place is to re-install Firefox.

My company IT spent 3 days trying to find the problem and couldn't. I have uninstalled and reinstalled so many times. All extensions are turned off, as are the two add-ons. I have been using Firefox for over a decade and prefer it to all other browsers, but I need to find a solution or I am going to have to move on. Help!!!

The connection was reset

The connection to the server was reset while the page was loading.

   The site could be temporarily unavailable or too busy. Try again in a few moments.
   If you are unable to load any pages, check your computer’s network connection.
   If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the web.

What can I do to resolve this problem.....Problem loading page

I can't access FSIS website which I need to do so for my job. This is what I get

"Firefox can't connect to the server at usda.gov Try connecting with a different device Check your modem or router Disconnect and reconnect to Wi-Fi"

I can't do any of those things because they make absolutely no sense. Nothing is wrong with my router, Wi-Fi. It's your program.

Hmm. We’re having trouble finding that site.

   Try again later
   Check your network connection
   Check that Firefox has permission to access the web (you might be connected but behind a firewall)

Contributor note: See also /questions/1576275 for the detailed error message.

Bonjour, depuis la mise à jour je ne peux plus me connecter sur mon NAS.

Il semble y avoir un problème sur ce site

Firefox ne peut pas se connecter au serveur à l’adresse .....

Par contre je peux me connecter depuis Safari donc le problème semble venir de Firefox.

I keep getting this message at the top of each site I go to: "You must log in to this network before you can access the Internet" It thinks I'm on a captive portal?? I'm at home on my own internet network. Why am I getting this message?

I guess I'm hoping an engineer or someone who works on firefox can resolve this cause it's always what pushes what me away.

I'll be sick of Chrome harvesting all my data, I'll download firefox, and I'll set it up. A couple years ago I deleted my chrome profile and switched completely over to firefox. I want to say once a month, I'll open firefox and websites won't load. If they preload they'll act like they're offline.

It's happened to me on Windows machines and Mac machines.

If someone wants to seriously drill down and figure out why this happens across platforms and DECADES, I am happy to provide logs and video chat or something.
