Error NS_ERROR_NET_INADEQUATE_SECURITY on every page

Hi, I've been having issues with Firefox for some time now. Every page I got to throws a NS_ERROR_NET_INADEQUATE_SECURITY error. I cannot fix it by setting network.http.spdy.enabled.http2 to false is because Firefox then starts crashing. In the past I've gone around the error by turning http2 off, but recently, first the developer edition, then after today's update to 91.0-0.1 of stable version Firefox crashes if I turn the feature off.

The developer Edition started throwing NS_ERROR_NET_INADEQUATE_SECURITY sometime in spring, then started crashing in June I think. The stable version followed soon as described above.

I am submitting this ticket from a beta version, which for some reason does not have this issue.

I thought it may be the Linux version of Eset, but removing it did not help. I cannot think of any other reason why am I getting those errors, but it seems I am alone because my colleagues don't seem to have this issue neither on macOS, nor Windows.

I note that there are 399 posts referring to this problem. The problem has existed on my PC for about 4-5 months.. DELL support has checked my computer, we have cleared cache and browser and tweaked other controls but nothing helps. I have no problem using Google Chrome. If so may people are having the same problem surely Firefox should be making an effort to fix the bug??!! Just drafted a reply to you from Firefox site but as frequently happens message appeared -

 Something about oops and an error message. When it occurs drafts do not save and messages do not transmit.

Sorry the screen print will not copy across.


I use Firefox as my main browser and it is inconvenient to have to swap between Firefox and Chrome

Can Firefox please fix this problem?

thank you mlmg

Problem with one website. I can't load and I see error: SSL_ERROR_INTERNAL_ERROR_ALERT

Dear Mozilla Community,

I have problems with one website. This website is poczta.wp.pl. Sometimes this can't be loaded. I see this error:

"SSL_ERROR_INTERNAL_ERROR_ALERT".

This is website with https protocol. What is the reason? Other websites works fine. I think that this is not problem with my router or internet provider because I changed both and it is still problem there. I had this problem also on another computer with Windows 10 operating system. I contacted with administrator of this website and they think that all is okay so they suggested me that this can be problem with browser or my computer.

This behavior is very hard to test because this issue is showed very rare. Sometime one time in one week and sometimes two time in one day. I don't know what is going on with this.

Can you help?

Unable to access the WEB Manager of my ARRIS SGB6782-AC Wireless Cable Modem Gateway (Error code: SSL_ERROR_UNSUPPORTED_VERSION

I need a FireFox feature that allows me to access the typical Cable Modem Gateway Web Manager addresses (192.168.0.1, 192.168.100.1, etc.) even when they have no security certificate.

I have been using a Arris SURFboard SBG6782-AC Wireless Cable Modem Gateway (purchased at TARGET) for over five years without significant issues. About three weeks ago my MoCA network began having issues. I tried to login to the WEB Manager of the Gateway at (192.168.0.1) using FireFox. I got the following FireFox Msg:

Secure Connection Failed

An error occurred during a connection to 192.168.0.1. Peer using unsupported version of security protocol.

Error code: SSL_ERROR_UNSUPPORTED_VERSION

   The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
   Please contact the website owners to inform them of this problem.

This website might not support the TLS 1.2 protocol, which is the minimum version supported by Firefox.

I finally used an old version of "Internet Explorer" which allowed me to bypass the security warning and connect via a direct ethernet port of the gateway. Evidently someone (Spectrum claims they didn't) downloaded a different firmware version into my Gateway. (D30GW-EAGLE-1.5.4.0-GA-10-NOSH) i.e. not the factory original version. The WEB Manager interface is different, password requirements are enhanced, the MoCA feature can't be enabled, and it seems Arris no longer provides a security certificate for the 192.168.0.1 Gateway address.

Considering the complete lack of cooperation of Spectrum and Arris, I think it is unlikely that I will ever be able to recover the factory original firmware; So... How about adding an "exception" feature to FireFox settings to allow me to at least access my "unsecure" Gateway. I really don't want to go back to using IE. By the way, I wrote this on a WIN 8.1 HP laptop. My main machine is a Dell XPS8300 running WIN 10.

Thanks, Robert R. Hurley

FYKI, the problem started occurring in November, 2021. It had never happened before. I repeat, this error is occuring only for Google-related sites, not for others.

What could be the problem? Please help!

Hello,

yes I know that version 3.6.28 is quite outdated now :) What is 20 years comparing to life on earth.. :)
Thing is that I need exactly this version of firefox because only with this version important web project works and now it is impossible to connect to server because I think TLS 1.0 not supported on server any more and old firefox can not handle the new one (do not know for sure, this is my opinion). So now I have very serious problem as I can not use needed web resource and deadline is tomorrow :(

So questions as follows: 1. Is there a way to force to work firefox 3 with web address https://varzybos.bki.lt 2. Maybe I can use non https:// version if all certificates are turned off in some way ?

I tried to add exception, then tried to play with various config option, nothing helped. So at this moment I am desperate.

Thank you so much.

Hi all,

while playing (or better "fighting"...) with a linux docker container on Win10/WSL2/Ubuntu for using the MS spfx tool chain, I generated a SEC_ERROR_REUSED_ISSUER_AND_SERIAL in FF85.0/Win10 by first setting up a certificate exception for a dev-cert (https://localhost:4321) and then have the certificate re-created.

As described the support article [https://support.mozilla.org/en-US/kb/Certificate-contains-the-same-serial...], I removed all certificate exceptions for localhost:* and deleted the "gulp" authority in options/security/certificates.

Unfortunately, the SEC_ERROR_REUSED_ISSUER_AND_SERIAL persists even after a restart of firefox.

Any help is very much appreciated...

Thanks & greetings Markus Fehn

I am unable to connect to the Nord VPN website or the Express VPN website because of a security issue with the Firefox Browser and I am unable to bypass the security and go to the site anyway. Here is what the message said: Did Not Connect: Potential Security Issue

Firefox detected a potential security threat and did not continue to www.nordvpn.com because this website requires a secure connection.

What can you do about it?

www.nordvpn.com 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 anti-virus software, you can reach out to the support teams for assistance. You can also notify the website’s administrator about the problem.

After auto update to FF 89.0, access to long-time Fidelity account is intermittently blocked as a security warning, or causes DSL line to drop at submission of account security code, or displays account entry page as plain text, not std HTML formatting, or most often results in a technical error page saying try again later. MS EDGE works fine, no issues. This is the only webpage this occurs on. Fidelity has no FF reported issues on their end nor does my IP supplier. Using desktop PC, running Win10/64-bit, DSL line @ ~ 2.3 Mbps. Using the "Light Theme" which was auto set with 89.0. This plus the new bastardized menus will push me to drop FF since I can't afford endless hours to fix basic functionality with ea update.
