When I opened up Firefox this evening, websites stopped working if "DNS over HTTPS" is set to "Max Protection". In some instances, such as YouTube, the website loads, but it acts like you're offline and tells me to turn on my Wi-Fi even though it's already on and running fine. Weirdly, it seems that setting DNS over HTTPS to Max Protection, loading a website, set DNS over HTTPS to a lower setting, and then reloading the website fixes the issue, but it'd still be nice if we didn't have to go through the hassle at all. Thank you for your time and patience.

Hi. I have a Dell Inspiron, it’s a few years old, and my computer is running windows. Today I was on a website, doing my assignments as usual when randomly the internet stopped working on the browser (I was on the web for about an hour before this). There was no change to my behavior, I had been on the same site for the whole hour, and had been interacting with the site during that time. My computer still says it’s connected to the internet, and I was even able to play an online game on my computer that I had downloaded, so it looks like my computer is connected to the internet. I’ve tried to clear my cache and open private windows but that didn’t help.

So I started using Firefox on my older and newer laptops, but I've noticed that on my older laptop it has started giving me the message "You must log in to this network before you can access the internet", although I am already signed in on my Mozilla account there too. My newer laptop has had no issues for the record. Both systems are running windows 11, both have the same account that I am using, etc. If it makes any difference, my older laptop is using an ethernet cable whilst the newer one is connected via Wi-Fi. When I ran into this issue yesterday on my old laptop, the issue somehow resolved itself after I created a bugzilla account, although I am unsure if this was coicidence, so now I am confused why the issue has showed up again. Awaiting any kind of help or advice, thank you.

I own the domain name sabbathcalendar.com which is redirected to my website at sabbathcalendar.org. Firefox consistently gives the following message:

"Hmm. We’re having trouble finding that site. We can’t connect to the server at www.sabbathcalendar.com."

It doesn't matter how I enter the URL. When I simply enter "sabbathcalendar.com" in either Brave or Microsoft Edge, both browsers will immediately connect to my website at sabbathcalendar.org with no problem.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

Hmm. We’re having trouble finding that site.

We can’t connect to the server at data.digital.costco.com.

Unable to connect

Firefox can’t establish a connection to the server at mesp.finance.gov.bd.

   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.

Current Behavior When Firefox is set to offline mode (File → Work Offline), the Developer Tools Network tab does not display request body of requests that web applications attempt to make. This creates a significant gap in debugging capabilities, as developers cannot inspect request payloads details that would normally be visible.

Requested Enhancement Enable the Network tab to capture and display attempted network requests payload even when offline mode is enabled

I know little to nothing about computers. My Mozilla account says it is disconnected whenever I come online. I do not manually disconnect ever. Keeps telling me that it cannot detect proxy even though my proxies are set to off.

When I click on Firefox and the to my email it says there is a problem with my internet. My internet is up and running fine. I have done everything it says Firefox can't connect to the server at mail.yahoo.com.
