Why am I no longer able to access 'allmusic.com on this browser?

I have an issue where I will frequently get the error pictured on random sites. This started happening a few years ago at my previous home with my old computer. It got so annoying that I had to switch to Brave browser for a while. I recently moved to a new residence, I have a new computer, and a different ISP and equipment, so I thought I would give Firefox a try again. To my shock, the issue still occurs exactly the same way at the same rate. I would say it is as frequent as 1 in 5 sites that I visit. If I hit the Try Again button 5 or so times, the site will load. The only thing I can think of that is common to the old computer and the new one is my Firefox account. Could there be something in my settings causing this to happen? I remember that I even tried Librewolf before switching to Brave but the issue occurred there as well. Any assistance or tips would be appreciated, I feel like I am going crazy at this point. xD

Cannot access <https://www.blacks.co.uk/> or any other outdoors website such as Millets ot Go Outdoors. Been going on for a long time now with error message:

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA). This prevents secure connections because the certificate is no longer trusted.

NOTE - I am using Firefox on my PC which is working fine. Issue is with my laptop Firefox.

Firefox was working fine, on my laptop and PC, until about 3 days ago. Started getting Tried to download various versions of Firefox. I am using Firefox on my PC with the same exact settings, network, Win 11 and Antivirus as my laptop. Firefox, version 128.6.0esr (64-bit) works fine on my PC, but does NOT on my laptop. I uninstalled FF and reinstalled it, changes Firewall to Windows on the laptop from my AV, NOTHING. Driving me crazy. HELP please.

On sites I have visited for years. It says to contact website owner, but I can't get on the website.

Any advice on what I can do?

I am getting this error in Firefox when I try to open certain webpages. These same links work in Google Chrome on the same device/connection.

Here's what I've tried:

In windows:

   Reset network settings
   Disabled firewall

In firefox:

   Cleared cache/cookies
   Turned off HTTPS-Only mode
   Turned DNS over HTTPS off
   Renaming cert9.db in profile folder to generate a new one
   Turned off all add-ons
   set network.http.http3.enable to false
   set security.tls.enable_0rtt_data to false

I've noticed that if I leave it on the tab, close firefox, then re-open it. It'll load in this one instance. However if I refresh/click anything on the website it then goes back to the error. I really can't figure out what the problem is

Hello,

I want to open this URL: https://compatibility.plantronics.com/deskphone Firefox 136.0.1 tells me: SEC_ERROR_REVOKED_CERTIFICATE

The same URL opens in Chrome and shows no sign of a security problem, as far as I can see (Chrome info attached).

What could be the cause? Firefox being to strict or Chrome just too relaxed?

Thanks in advance.

Hello new here, I’ve been facing a frustrating issue with my website on Firefox, and I’m unable to find a solution despite searching for hours. My website, https://snakeaimtool.pro/, sometimes fails to reload and displays the error: "The page isn’t redirecting properly."

I contacted my hosting support, and they confirmed that there’s no issue with the server. Everything is working fine on their end.

I realized the issue might be specific to Firefox because I primarily use Firefox and don’t face this problem on other browsers like Chrome.

I’ve been searching for solutions on YouTube and other forums, but nothing has worked so far. Could someone please suggest a possible solution or guide me on how to resolve this issue? Thank you in advance for your help, I attached the issue image!

I am being prevented to access any sites I need just because they require some personal data from me. After the initial Norton (1). The message I receive -

Secure Connection Failed

(1) Norton prevents acess saying Dangerous web page, threat category URL : phishing I take the more options and indicate faulse reporting then as above !!!

I went to work and when I returned a new router was installed and ever since I get errors on almost all sites I visit. It is the potential security issue, requires secure connection and when I look into the info it says the certificate is being denied because it is self signed. And anytime I go to hit learn more I receive a 400 error and cannot continue. I am also unable to update apps I have on my pc or connect to the internet using anything besides a browser. I get the same kind of error on edge as well as Firefox.

I have already set things up so I am using no proxy and I do not have https only mode enabled.

The only constant is that I can open YouTube and watch videos. I thought this meant it was a dns issue but I have tried several fixes for dns issues and they didn't work.

I would attach photos of the error but Mozilla is also unable to open due to the errors so I'm filling this out on mobile.

Unable to connect

Firefox can’t establish a connection to the server at 127.0.0.1:8080.

   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.

HOW TO CONNECT

Good day,

I'm using Selenium with Firefox in Python to automate browser testing, but I keep encountering captchas that prevent my script from proceeding. Additionally, I receive an error stating that "the browser is being automated" (Reason: Marionette).

My intended automation flow:

1. Open Firefox
2. Go to www.google.com
3. Search for "YouTube"
4. Click on the YouTube link
5. Search for a video
6. Play the video

However, captchas appear during the process, and I suspect it's because Firefox detects that it's automated. Is there a way to disable automation detection in Firefox or configure Marionette to reduce captchas when using Selenium in Python?

Any guidance or workarounds would be greatly appreciated.

Thank you!
