There is a site I visit regularly that will not connect. I get an error 429 code. This doesn't happen with any other site I've used recently, and I can access the site with my iPad. I've tried clearing cookies and restarting the computer, but still can't get to this site. Any ideas?

Secure Connection Failed

The error SEC_ERROR_REVOKED_CERTIFICATE means that the website's SSL/TLS certificate has been revoked by the certificate authority (CA).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.

I get this error code when I click this link: https://app.getresponse.com/click.html?x=a62b&co=zuZIy&lc=hxmU75&mc=Iu&s=Hb9xCO&u=qU&z=EF9yGAP&

Using Windows 11 just reloaded on new hard drive (Solid State). Old hard drive took up smoking. This error does not happen on any other site and did not happen before.

Examples of webpages I've entered today that receive an error message are https://leafscape.com & Mint Mobile

Error 403 Forbidden

Forbidden Error 54113

What is this about? Just trying to reach https://www.scientificamerican.com/

Never happened before

This does not happen when accessing through Firefox on my iphone....just on the macbook

When I try to read my webmail I get this:

Secure Connection Failed An error occurred during a (https) connection to www.nebula.fi. Peer’s Certificate has been revoked. Error code: SEC_ERROR_REVOKED_CERTIFICATE

The same address www.nebula.fi works fine in Edge browser, which claims: Connection is secure. This site has a valid certificate, issued by a trusted authority.

I would prefer using Firefox. Is it somehow possible?

Hello! I started encountering this problem as I updated my OS to windows 11. I had eset nod antivirus, but uninstalling it nothing changed. Tried to change MTU cache size through CMD. Changed different DNSes Tried to disable all protection settings in browser and in windows settings. Deleted all extensions. NOTHING helped except clearing cache of the browser, but this is fixing problem only before first browser restart. Other browser on laptop works normally without any issues.

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

We have systems on our network that run Mozilla Firefox when accessing a specific URL are able to do so with no issues. Then we have other systems in our network that run Mozilla Firefox when accessing that same URL received the following error:

Secure Connection Failed

An error occurred during a connection to "URL". PR_END_OF_FILE_ERROR

Error code: PR_END_OF_FILE_ERROR

Both are running the same version of Firefox. The only difference I have found is the DNS over HTTPS status. On the one that the user is able to access the URL, the DNS over HTTPS status is off. On the one that the user is unable to access the same URL, the DNS over HTTPS status is Active using the provider Cloudflare.

These are both brand new install of Firefox and there was no configuration changes. We don't use any GPO's or anything else to manage Firefox. Why would one be off and the other active? This is causing issues.

Hello, when I browse the internet, randomly the certificates seem to break as I get https certificates for sites that seem to have nothing to do with the sites that i intend to visit. Then errors like the ones in the screenshots appear. Usually reloading the website helps and then the certificate displayed seems to be correct. I did make sure to upgrade to the latest version of FF (136.0) and I did clear all cookies, but it didnt help. I do not really have any idea where to start searching or what might cause this, tia for help. kind regards Thomas

am experiencing the 'fresh new look' error pages, and am rather annoyed that the raw response code isn't displayed on the initial error page, and must click 'learn more...' to reveal the underlying response code. how can i return the error code to the initial error page and avoid the unnecessary extra click to get at that info?

(ps. i can assure you that by obscuring this basic piece of info, it definitely isn't 'making it clearer what went wrong', despite what the 149.0 patch notes claim)

Dear Sir or Madam: I seem to have a compatibility problem with my firefox browser. Not always, but often, I get a 502 error when I try to log in to my bank account. After contacting my bank, I found out that their program is not compatible with firefox and that I should use Google, which choose to avoid. Is there a patch or fix that can get rid of the 502 error and allow me to continue using Firefox, which I have used for almost twenty years. I don't want to switch to Google, EVER! Please let me know what options I might Have.

Respectivly, Louis Osip

So I'm getting the reset error code on only my twitch and YouTube tabs, now I have no add ons, I tried the cert9 file thing and that didn't work. I tried resetting my cache and that does not work for me, the issue is it's only for those 2 websites, everything else works just fine. I have tried a different profile that didn't work, I tried resetting Firefox and that didn't work, I tried resetting the router that also didn't work at all. I tried the troubleshooting firefox and same result, I'm in the original firefox, or rather not the troubleshoot one. I also tried signing out of my firefox account, that also did not work, and so I'm stuck on how I can get back my tabs that arent opening. Also I did try opening them as new tabs but they didnt work as well.
