Intermittent “SEC_ERROR_OCSP_INVALID_SIGNING_CERT” error on my site in Firefox

Hello, I run a movie and drama-related website: https://tvmon.com.co/. Recently, I’ve noticed that Firefox occasionally throws the following error when trying to access the site:

"Secure Connection Failed An error occurred during a connection to tvmon.com.co. . The OCSP response contains an invalid signing certificate. Error code: SEC_ERROR_OCSP_INVALID_SIGNING_CERT"

This issue is very strange because:

  1. The site loads fine in Chrome, Edge, and Safari.
  1. My SSL/TLS certificate is valid, up-to-date, and passes external tests (SSL Labs, etc.).
  1. The error only appears occasionally in Firefox, refreshing sometimes fixes it, sometimes not.
  1. Hosting and server logs show no issues at all.

I suspect this is related to Firefox’s stricter OCSP validation, but I’m not sure how to debug or resolve it. Since my site streams drama and movie content, this error is frustrating for users who rely on Firefox.

Has anyone else experienced this intermittent OCSP signing certificate error? Is there a known fix or workaround for Firefox-specific validation issues?

Hi. I'm in Windows 10 Extension using latest version of Firefox 145.0.2.

Every time I try to log into my Gmail account, a Windows Security Pop up says: "Making sure it's you. Please sign in to google.com. This request is coming from Firefox, published by Mozilla Corporation."

I'm already trying to log into gmail using my user name and password! I cancel out of the pop up and then it takes several tries to finally log in to gmail.

Is there any way to disable this pop up request at Firefox's end?

Thank you. JHL

Had to recently reset my browser and lost all my history. Apparently it messed up my custom settings in some way as well.

New Tab still shows my FF homepage with shortcuts and history gone - I've managed to get those back but with one huge problem:

- Clicking on a shortcut opens it in the same tab, whereas earlier I had it working when clicking on a shortcut would open it IN A NEW TAB.

Where's the setting in about:config to fix this???

If this feature has been removed - why???

I can't delete history. I know how to do it (ie menu, click "clear recent history" etc etc) but it just doesn't do it. I've uninstalled Firefox and taken the option to "refresh" instead of reinstall. Didn't work. Uninstalled it again. In the reinstallation I asked that it NOT import my settings etc but it did it anyway. Back came Firefox, complete with my history! I just can't get a fresh start. With regret, I'm starting to use a different browser. I dislike doing that but at present I have no choice. Whenever I use Firefox, I just clutter up the place and can't get rid of history.

Hello,

"The bookmarks and history system will not be functional" error message has suddenly appeared in just the past couple of days on my new DELL Inspiron 15 3535 with Windows 11. I have followed the first few items on the Mozilla Support page that comes up as soon as the initial Firefox opening page appears and that has not corrected the problem.

I have tried to follow the next few steps but can't really find what it calls for because I don't understand what it's talking about. I am not of the tech generation and do not speak the tech language. Most of the terms in there I do not know what or where they are on the laptop.

Is there anybody who could help me saw through the terminology and give me some ideas on how to simply solve my problem? All I really want to do is get to where my bookmarks are hidden and put them back in place where I can use them again.

Thank you in advance for any help anybody might have.

Kind Regards, Tom B.

I am trying to find the files for my passwords from an old profile after Firefox just updated and created a new profile. I have just created a Mozzilla account so my profile can start to automatically update with all of my old passwords, but I first need to manually transfer them from my old profile that didn't have a Mozzilla account yet. I have been following the steps for doing so from the "help" pages, but I haven't been able to find the files for my passwords.
