Firefox 社群討論區

Hi; I use Firefox on my phone and my laptop both. In my laptop (Lecoo pro 14, Ubuntu 26.04) in a domain range browser gives me security alarm and don't let me get in. This is normal but when I use other browser in my laptop or Firefox on my phone (s25 ultra) there is no problem at all and it works well! I tried all things. run commands like: sudo snap remove --purge firefox | sudo snap install firefox, sudo apt search firefox/mozilla and than reinstall all installed packages and clear all caches on settings. But none of them worked. Thanks for your responsibility and making such great open-source app.

I am trying to access my QNAP NAS configuration page within my home LAN from a newly installed Linux PC with Firefox 147.0.1. Firefox won't let me access the page, popping up an error page:

Warning: Potential Security Risk Ahead

Firefox detected a potential security threat and did not continue to nessy.fritz.box. If you visit this site, attackers could try to steal information like your passwords, emails, or credit card details.

I have verified that the claimed risk is nonexistant, but Firefox does not allow me to bypass the warning. There is no "Proceed anyway" or "Advanced..." button as claimed in various help articles.

How can I convince Firefox that I know what I am doing?

NB: The same page is accessible, also with Firefox 147.0.1, from a Windows PC.

It is very annoying to not be able to have acces to my scholarship, my accommodation, or just my whole student services in general even if they are websites from the french government. I cannot bypass the mozilla security risk warning so I'm asking for some help here. the website is https://messervices.etudiant.gouv.fr/

it would be a great update to be able to go past the warnings in the future, being unable to do so forces users to switch of browser, especially when you cannot have acces to such websites which are essential for students

I have a home server 192.168.0.240 in my local network. Firefox does not let me in to my own pages. On the address line appears text "Not secure",

I have found no way to get in. I have there REALLY IMPORTANT TOOLS AND MATERIAL and I need it AS SOON AS POSSIBLE !!!!

This is really stupid. I have used these pages until this weekend. I have had this problem many years, but always found some way to make it work. I am NOT going to buy a certificate to every server I have home. it costs $$$$.

I am getting more frequent "Firefox can’t create a secure connection to the server " messages. This isn't inherently an issue, but on most of them there is no longer a "continue anyway" button. I know your first response will be "It's for your safety." Well now, I'm a big boy, 58 to be exact, and I wear my big boy pants everyday. I am perfectly capable of deciding how much risk I'm willing to accept. This especially applies to sights I am familiar with and trust that suddenly trigger your warning for some mysterious reason. This is becoming a large problem for me and if there isn't a fix for it I may have to reconsider my use of Firefox.

Your computer thinks it is May 1, 2026, which prevents Firefox from connecting securely. To visit www.olx.com.br, update your computer clock in your system settings to the current date, time, and time zone, and then refresh www.olx.com.br.

When trying to access many popular websites with Firefox on my Fedora 43 installation, I am greeted with a security warning page with the SEC_ERROR_UNKNOWN_ISSUER error. For most of these websites I can simply accept and continue, but HSTS-only sites will not permit this.

Affected websites include but are not limited to (based on exceptions in the certificates section of Firefox settings):

• github.io (many subdomains)
• purdue.edu (many subdomains)
• iu.edu
• ebay.com
• cbsnews.com
• iwm.org.uk
• home.cern
• celestrak.org

Any help in resolving this is appreciated.

Running Surfshark on Windows 10 or 11 and Unbuntu 24.04. Some sites and attachments giving error failures. Happening with Firefox and Edge. Need troubleshoot source.

Subject: Urgent Assistance Needed with Certificate Installation

Dear Team,

I hope this message finds you well. I am in urgent need of assistance regarding a Linux-based system where we have the Firefox browser installed. I need to establish a secure connection with one of my servers, which requires the installation of a certificate.

However, I am unable to locate the certificate export button in the certificate view or anywhere else in the browser. I have tried several methods without success.

Could you please help me with this issue as soon as possible? Your guidance would be greatly appreciated.

Thank you very much!

Best regards, Kishor

I'm trying to access a local web application (GoPhish) running at https://127.0.0.1:3333 on Kali Linux. Firefox is showing a security warning and won't let me access the site . How can l bypass this warning safely, or add an exception for local addresses with self-singned certificates?
