Firefox Community Forum

For the last day or so, Firefox is refusing to resolve any web pages. I have had to write this in Safari, so I can't share the data from Firefox. Sorry.

Please help, thank you :)

2017 iMac, OS 13.6.9, Firefox 140.0.4

Firefox ne peut établir de connexion avec le serveur à l’adresse dl.google.com. Firefox cannot establish a connection with the server at dl.google.com.

I just downloaded version 140.0.4 for Mac. Now Firefox will not open any website pages. I added Firefox to the list of allowed apps in my firewall settings but that did not fix the problem. Please help. Thank you.

how do i reload all firefox windows after vpn has trouble reconnecting. the image shows all of the "server not found" after the vpn has trouble reconnecting to another server location. thank you

i have problem with setting up my proxy. i choose manual proxy configuration, fill the HTTP Proxy & port. When i click ok then input username & password but it keep asking for the username & password. (I have asked the proxy provider they say the proxy is good, no problem)

I have been trying to make fox news my home page on new computer with windows 11 .When I type in https.//www.foxnews.com firefox says it can't connect to this site.

I CAN NOT RUN WBSITE OF NREGA.NIC.IN IN MOZILLA FIRFOX PLEASE RESOLVE IT PROBLEM IS GIVEN BELOW Hmm. We’re having trouble finding that site.

We can’t connect to the server at nerega.nic.in.

If you entered the right address, you can:

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

Unable to connect

An error occurred during a connection to www.facebook.com.

   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.

I am on a MacBookPro running MacOS 15.5.

My FireFox automatically updated to 139.0.4 on June 10th. Since then, my ability to access the internet with FireFox only has been intermittent - I can connect for a variable number seconds and then it disconnects for minutes or hours. I have no problems connecting to the internet with Chrome or Safari, or with other applications. My perusal of the forums leads me to believe that it is the latest update that is causing the problems.

Has anyone experienced this problem and/or does anyone have a fix? Thanks in advance.
