Firefox Support Forum

Hi, for about 14 days I get random certificate warnings - even on well known websites. They vary from SSL_ERROR_BAD_CERT_DOMAIN to SEC_ERROR_UNKNOWN_ISSUER... even on websites like x.com or LinkedIn. At the same time I got a new router from my ISP. But I am not sure, if this is connected somehow or if I got a Man-in-the-Middle or a virus. Malwarebytes & Co don´t find anything. I have resetted Firefox, too. But nothing helps. I get these errors in Chrome, too, sometimes. But not as often. Any ideas anybody? TIA!!!

I am getting "Secure Connection Failed", Ive seen literally hundereds of same error also exist here. Like most of default solution (which is below) did not work for me. My laptops time is correct, And I highly doubt reddit and most of internet has issue with its security certificates. And other browser works just fine. So What is my solution other than immigrating to new browser?

I went to settings and then to privacy and security and tried to find auto fill to remove credit card info. I couldn't find the setting the browser told me to find.

I'm hoping to get some help with disabling the Insecure connection password warning in Firefox version 115.11.0.

In previous versions, I could disable this warning through the about:config settings. However, I couldn't find the specific setting (security.insecure_field_warning.contextual.enabled) that was mentioned in some online resources.

I understand the security risks involved in disabling these warnings, and I only intend to do this on a trusted website on my local network.

Could you please advise on the best approach for achieving this in Firefox 115.11.0, or any alternative solutions to manage insecure connection warnings for trusted local sites?

Thanks in advance for your help!

Firefox does not allow website to access my location even though I keep allowing the website to access my location. I select the allow button and also did this both with and without the box checked to remember the decision. I also go into Settings - Privacy & Security - Location settings. I allow there. Nothing helps.

I would like to further secure my passwords but don't want to have to enter the primary password every time I start the browser. I would like it to only prompt me if a password is needed. I can go days without needing a password to be entered and open and close Firefox every time I use it. It gets tedious. Thanks!

Yesterday firefox private window comes up on my browser...I do NOT want that, how to get rid of it?? My desktop is set up with menus for quick reference; I cannot get past this private window

I use firefox (as mozilla) for decades ago. Never had issues, is super easy, fast and ...secure (?) A hacker last week have access on my Firefox, download ALL my saved passwords as CSV... as a plain TEXT and ATTACKS on my entire life!!! And the nightmare goes on and on... Stole my primary Google Account, Facebook, Instagram, Ubisoft, PayPal, Microsoft Account.... and other 20 sites beside this. For GOD sake, didn't you EVER think to place an extra security layer on this EXTREMELY SENSITIVE details??? A master password? 2FA or something else? Are you serious??? I'm so sorry BUT YOU'RE LOST MY TRUST!!!! Period!!! Give a change to your selves and PROTECT YOUR CUSTOMERS!

I can no longer connect to X ray images using your browser. The links are in EPIC. The X ray system is eUnity. If I can no longer connect I will have to switch browsers.

How do I turn on autofill in firefox 125/126? There are help pages that say go to settings>privacy> and turn autofill on. But there is no autofill mentioned anywhere in that page. The only reference that autofill comes up with when typed in the search bar in settings is in import settings. How is this so difficult to enable, its basic functionality 10 years ago. I've also tried going to extensions.formautofill.supportedCountries and extensions.formautofill.addresses.supportedCountries and adding my country (why this is a thing is bizarre as well).

Firefox periodically says I am "forbidden" to enter my Kaiser website (KP.org). I know what Mozilla recommends as a fix, which is to clear data and cookies. But this creates more problems because I have to re-enter passwords and other settings. This is a problem Mozilla's website reports has been occurring for YEARS! Why can't Mozilla/Firefox fix this? Please tell me there is a better way to fix this problem.

Hello everyone! I am having a pretty strange issue with my [website ], it shows an SSL certificate on all the other browsers, but, on Mozilla Firefox, it shows not secure issue, which is quite pressing. Can anybody tell me what's wrong here?

I am migrating to a new laptop. The new laptop keeps asking me for a primary password. I have never set one up. This issue doesn't happen on the old machine, only the new one. It also won't let me disable the pop-up that asks for the primary password. Please advise.
