Firefox Community Forum

Firefox new today stopped from loading some of my own websites that are http. Some http sites still work. Sends me to my hosting site https://www.forexample.org/login_up.php Cleared all history and caches. No change. Turned off http to https. No change. Again, just started today with no other changes on my part.

I have been using the site codeskulptor.org for years. Creating images and saving them easily. Lately I have been getting a little shield with a red cross thru it up in the front of the url bar for the page images i wish to save but am not able to as easily as before. I would like Mozilla to approve the pages i spin off as images in new tabs from codeskulptor.org.

Thank you, Ben Winsor

Suddenly this week all links from/for various sources/websites have stopped working in Firefox: "Error Code: SSL_ERROR_RX_RECORD_TOO_LONG".

Links from common trusted sources that I access regularly no longer work. All display the same error message seen above. So it seems like a change by Firefox and not the websites. New York Times Economist USAA Comcast

Can't get onto national-lottery.co.uk site. Error code: SSL_ERROR_NO_CYPHER_OVERLAP But am using latest Firefox (152.0.6) Solution in no-technical language please...

I would like to understand how DNS over HTTPS impacts browsing speed and privacy in Firefox.

Details: Hello everyone,

I am currently exploring Firefox privacy and network settings, especially DNS over HTTPS (DoH). I noticed that enabling this feature slightly changes website loading behavior on some networks.

I would like to ask:

Does DNS over HTTPS introduce additional latency? Are there performance differences between providers? Can corporate or public Wi-Fi networks interfere with DoH requests? Is there a recommended configuration for balancing privacy and performance?

I’m interested in both technical explanations and real-world experiences from Firefox users.

Thank you.

Hi, I'm using a policie file to force a family-dns. Ive written the current code down below. Unfortunately this leaves the "manage exeption"-button open, where its possible to simply bypass the block for a specific site. Is there a way to lock this button in the policie file? Thank you very much. {

 "policies": {
   "DNSOverHTTPS": {
     "Enabled": true,
     "Locked": true,
     "ProviderURL": "https://doh16.jusprogdns.com/dns-query"
   },
   "Preferences": {
     "network.trr.mode": {
       "Value": 3,
       "Status": "locked"
     }
   }
 }

Using FF 140.10.1 esr on a windows pc I noticed (probably long after the fact and numerous updates) that there's no longer https:// in the address bar. Having some recent issues with security made me look for this.

When I switched to Edge, the https:// was in the adddresses I was using. There is a lock symbol, but the locks seem to change in their appearance from one browser or website to the next.

Was this verification sign removed and, if so, why?  

Thank you.

Dear Mozilla Team,

I kindly ask you to add support for the X25519MLKEM768 hybrid post-quantum key exchange to the domain detectportal.firefox.com (the URL used by Firefox connection testing). This small change would significantly strengthen privacy protection for millions of users who rely on Firefox's connection test URL. As you know, this mechanism has already been successfully implemented on almost all of your other domains. Extending the same protection to detectportal.firefox.com would ensure consistency and close the remaining gap. Thank you very much for your ongoing work on privacy and post-quantum cryptography. I would greatly appreciate your attention to this request. Best regards, Anonymous
