I-Firefox Community Forum

To be honest. Firefox is starting to be a big pain to use. I'm starting to see more and more of this screen where it say's "Be careful. Something doesn't look right" Even when i go to the advance and say proceed. Nothing happens and i'm getting no where. I know many of the sites don't have anything to do with asking for credit card, Scam or even having popup's. I test the sites in other browsers and there work without any issues. But Firefox is starting to lock me out of many sites due to this. How can i make this stop. As i used Firefox for many years.

The sample that is in the screenshot is a Anime data base that i have also used for years. But today shows this. But was working fine yesteday. What is going on and how can i fix it. So i can start using the browser that i love on the sites i want to.

I have started receiving a secure connection failed error message for a portal log-in website that worked fine for the past 6-7 months (see attached document). Other people in my group use Firefox and Bitdefender to access the portal and none of them are having this issue.

I originally believed the problem to be my anti-virus (Bitdefender) and worked with them to resolve the problems. After trying various solutions including clearing my cache, using private mode and turning off different components of their software, Bitdefender believes the problem is with my browser setting and not their software. I also tried accessing the portal using Chrome in both regular and incognito modes and cannot access the site which would seem to rule out the problem being a Firefox browser problem but contacting Firefox support seems to be the next logical step.

I have been to the Firefox FAQ and saw similar problems with potential solutions - DNS over HTTPS, TLSKEYLOGGING issues, add-on exceptions - none of which worked. I have the most recent version of Firefox and am running Windows 11 home version.

Sometimes if I hit refresh after receiving the error message, the browser will try to connect and I will get a server time out message. If I keep hitting "try again", sometimes the portal log-in screen will appear and allow me to log-in. The key word is "sometimes" since often I just keep getting the server time out message.

Any ideas for me to try from this forum?

The SSL cert has been installed by the entity (Gridhost) from whom I have bought it for 20 years. And as explained, Firefox still shows it as Not Secure while Chrome say it is secure.

Beginning today, I suddenly cannot access numerous websites when I use Mozilla Firefox 151.0.2. Examples include Amazon, and Google, et al. Attempts to do so consistently fail at the point of performing a TLS handshake, when I am advised that "secure connection failed". Kindly refer to the attached screenshots. I have no difficulty whatsoever accessing the same websites when I use other browsers, such as Google Chrome and MS Edge. I previously had Mozilla Firefox enabled as my default browser, but I have had to change this, given these "challenges". Please advise how I can fix this. Best regards and many thanks.

Why i need every time i restart the firefox esr accept the cudy.net certificate? Look the picture.

Is there a way to add it as exclude this certificate and NOT ask me every time i restart the firefox esr to accept this certificate?

Try Again

Firefox detected a potential security threat and did not continue to apps.ngte-welfaretrust.gov.bd because this website requires a secure connection.

What can you do about it?

apps.ngte-welfaretrust.gov.bd has a security policy called HTTP Strict Transport Security (HSTS), which means that Firefox can only connect to it securely. You can’t add an exception to visit this site.

The issue is most likely with the website, and there is nothing you can do to resolve it.

If you are on a corporate network or using antivirus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

Up until today I have never had trouble accessing My [edited from community support forum] @deamer.org address for the Deamer.org website But to day I am completely block our by Fire fox for even getting to Deamer.org and I get this message Did Not Connect: Potential Security Issue

Firefox detected an issue and did not continue to 408916.svc.e1m.net. The website is either misconfigured or your computer clock is set to the wrong time.

It’s likely the website’s certificate is expired, which prevents Firefox from connecting securely.

Dear Mozilla Support, I would like to ask about Firefox's plans regarding the recent changes affecting SSL/TLS certificates for websites hosted in Russia. As you may know, several international Certificate Authorities have announced that they will revoke or stop issuing trusted certificates for Russian domains. This may cause many legitimate websites to become inaccessible in browsers because their certificates are no longer trusted by the default root store. I understand that Mozilla places a strong emphasis on web security and maintaining a trusted certificate ecosystem. However, I would like to know whether Mozilla has considered any technical solution or mitigation for users who may need to access these websites. For example:

• Is Mozilla planning to provide any workaround or optional feature that would allow users to continue accessing such websites safely?
• Will Firefox receive any updates or patches related to this situation?
• Is the current recommendation simply to manually install additional trusted root certificates, or is there another supported approach?

I am  interested in understanding whether there are any official plans or recommendations for users affected by these certificate changes.

Thank you for your time and for your work on Firefox.

Kind regards, Mikhail M.
