Using Firefox browser is resulting in a message that states that Firefox is not operable with mail.fcconnexion.net. Your info is stating that there is a problem with the website. If that is the case then why using Microsoft Edge or Chrome allows access?

Recently Firefox has stopped recognizing website exceptions entered into pop-up blocker manage exceptions. I have deleted all websites and reentered a couple but none are being recognized. therefore these websites are blocked to me. One is https://www.foxnews.com/. This problem started after the last Firefox update.

I Have Windows 11 and Firefox version 158.How do I stop getting gray Mozilla Firefox pop up boxes with notifications in,sometimes get 2 the same.Firefox is my default browser.

I am trying to access AdBlock which I know I activated on my Mozilla, but can't find any reference to it whatsoever. I would like to disable it for one or two sites.

Be careful. Something doesn’t look right.

Firefox spotted a potentially serious security issue with intranet.mahaforest.gov.in. Someone pretending to be the site could try to steal things like credit card info, passwords, or emails.

The cloudflare will not let me access chatgpt or other sites and I have tried doing the troubleshooting but not getting anywhere. I am not computer savvy so I dont know how to fix this

Hi. In Firefox versions newer than 153.0.4, I can't connect to my camera when I'm away from home. I see that the message about accepting the PLUGIN has changed a bit, and now a prompt to grant permissions pops up near the search bar. I think this problem occurred about 1.5 years ago. The camera is a FOSCAM, and I have the plugin from their website installed.

Interestingly, in Firefox versions newer than 154.0, I can log in and manage the camera via the web, but only on localhost at home :) The plugin prompt appears, and everything works fine.

Unfortunately, accessing it from outside my home doesn’t work, even though the camera’s login page loads. After entering my username and password, I get a “TIME OUT” message from the browser.

I’ve tried everything—creating a clean new profile, etc. Starting with version 153.0.4, you can only log in via localhost; otherwise, only the login page loads, and you get a “TIMEOUT” error after entering your username and password.

Please forgive me if I’m posting this in the wrong place, but I’m not very up-to-date and I’m using a translator.

Best regards.

YouTube videos on Nightly are flickering with green and the frames of the video. I am on Firefox Nightly, so it's really just me not sure how to report this bug.. Thanks!

Despite re-installing Firefox sidebar is still missing (I spent 3 full days trying to fix it before re-installing). I also can't obtain another tab - I'm restricted just to the one page I'm currently using

My system • Windows 11 on a Dell laptop. • Firefox Version 157, my default browser. • Norton 360 Standard. • Two Firefox profiles; the warning appears in both. • Firefox Troubleshooting Mode does not eliminate the warning https://support.mozilla.org/en-US/kb/sslkeylogfile-warning?utm_source=chatgpt.com

What I have observed The warning appears on Firefox network-error pages, including when the internet is disconnected or I enter an incorrect URL. A particularly reproducible example occurs after I successfully log in to Kotak Net Banking and select Help → Raise a Query. Firefox then displays a connection/privacy warning associated with the embedded page. I do not see the same behaviour in Chrome or Firefox Private Browsing when performing the equivalent Kotak steps. Troubleshooting already completed 1. Norton Safe Web HTTPS scanning was disabled and re-enabled without resolving the issue. 2. QUIC/HTTP3 scanning, WebSocket Protocol Scanning and DNS/DoH scanning were individually tested without resolving it. 3. Firefox Enterprise Policies are inactive. 4. I found no SSLKEYLOGFILE entry in either Windows User Variables or System Variables. 5. Norton and Dell malware scans found no malware. 6. The warning also occurs when I connect through a mobile phone hotspot rather than my usual BSNL connection. Questions for Mozilla's technical contributors 1. Does this warning establish that Firefox detects SSLKEYLOGFILE, or could another mechanism produce the same message? 2. Can the variable be inherited by Firefox from a parent process or injected into its running process even when it is absent from the Windows User and System Variables? 3. What is the safest way to identify which process or security product is setting it on Windows 11? 4. Is there a known interaction between Firefox 157 and Norton 360 Standard that could explain this behaviour? 5. What evidence should I collect to distinguish a Norton issue from a Firefox issue without disabling security protections or modifying Windows settings? I am not looking to disable security features indiscriminately. I want to identify the actual cause and, if Norton is responsible, determine the precise setting that needs attention. I would particularly appreciate a response from a contributor with Windows networking, Firefox TLS or security-software diagnostic experience. Thank you.
