Create custom DNS providers list to "DNS over HTTPS" "Choose provider" menu (Settings > Privacy & Security - DNS over HTTPS) This can be applied to any Mozilla based browser.

1. Write about:config in url-bar and press [Enter].

2. In the "Search preference name" box Find the "doh-rollout.provider-list" value.

2.a. Create it if not exist by choosing: "String" value and press "+" (add). 2.b. On the right side of the value, Write the '*one string code'. - (if a code already exist, select all code [Ctrl+A] & copy [Ctrl+C] and paste [Ctrl+V] in a notepad and Save it so to keep backup with the previous setting.)

The '*one string code': [ { "UIName": "Cloudflare: Mozilla uri: (https://mozilla.cloudflare-dns.com/dns-query)",

You can modify the code based on your preferences to change the "Choose provider" menu list.

Lately when following links from google searches to some sites I get a "can't find" or "access not allowed". These sites tend to be hardware stores - specifically Home Depot or Lowes and some times Walmart. It is NOT my OS!! Because I copy the URL and paste it into Chrome and it works just fine.

Obviously switching to Chrome would solve this issue - but I've used Firefox for years and prefer to stick with it.

What's changing out there that is causing these incompatibilities?

Where can I download a fresh Firefox 115.33.0esr (64-bit) browser for Win-7 because the one I have installed is so corrupted and I can't seem to be able to fix it.

certain sites ( like FedEx tracking ) say that I can't visit because my browser needs an update. but I checked and Mozilla says that I AM up to date . last update April 28 What can I do to fix this?

I need help with an issue and would like guidance on how to resolve it. I can provide relevant details, including what happened, any error messages, what I’ve already tried, and the steps needed to reproduce the problem.

I have been blocked from making payments from the billpayer on my accounts with credit union. Even my Gmail says I am using an outdated browser but my settings history says it is all up to date. Bills are due and I need help in clearing this up. I am on Windows 7 Home Premium.Is there something further I need to adjust?

I am able to open the Lowe's and Home Depot home pages but receive an error message like this when I try to load any other pages for their products or my accounts: "You don't have permission to access "www.lowes.com/l/help/truck-delivery"" on this server. Reference #18.70fe3d17.1774785973.a686bfa https://errors.edgesuite.net/18.70fe3d17.1774785973.a686bfa"

I tried to resolve this by calling their support teams, but they were not able to help me from their end. This leads me to believe that something on my desktop is causing this. I do not have this problem with any other websites. Can you help me resolve this?

Since the last few days weather.com will not work with my version of Firefox. I use 115.37.0esr version of Firefox. Since the last few days Weather.com seems like it is loading and displays the page correctly for half a second but as soon as the page appears, it disappears leaving a small message midscreen that says " This page couldn’t load - Reload to try again, or go back."

I tried turning off my adblocker but that made no difference. Anyone got any ideas? I really like weather.com. It's one of those nice websites that are like when the web was new and was just a useful thing for everyone.

Firefox has stopped displaying the COX home page at https://www.cox.com/residential/home.html?campcode=redir-myc-hom . I can see the back pages if I connect to them from a link, but the home pages does not display. All I get is a error that says, "Oops something is wrong. Please try again later. And a circle that just "buffers" constantly. If I connect though a book mark to the payment page or one of the other pages I can see it. The error used to start for a minute when I turned my computer on and correct itself but now it is permanent.

Cox is telling me that it is a Firefox issue and I should get "another browser". But there is nothing better then Firefox. Everyone else works, even Google and Yahoo, just not COX.

Thanks.

Why does my older computer running Windows 7 keep losing the ability to access "https:// sites"?

To resolve, I have to reset the network adapter (sometimes successful) or restart the computer to access these sites.
