Firefox 技術支援討論區

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.

Version: 91.0.1 Settings--> Privacy and Security -->View Certificates-->Your certificates--> pick target cert to delete-->click ok on confirmation window --> click ok on Certificate manager window.

Restart FF, Settings--> Privacy and Security -->View Certificates-->Your certificates, the deleted cert is on the list again.

The same happens on that under Authorities.

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

I got a new printer today. Epson WorkForce Pro 3820. When I access the web interface, I get this error. I can proceed past it but I'd like to know how to get rid of the error. Thank you. Barbara

I am getting a Secure Connection Failed error on every website I try to log into on my laptop. The issue is not occurring on my desktop or either of my iOS devices under the same login account. I have tried every "fix" I can find through the FAQ's and through online googling, nothing has worked. I don't have any conflicting apps or security features that I can find. I have tried purging the history/cookies, un-installing and re-installing. After a re-install the websites will work for about 5 minutes then I receive the same Error message. Please help!

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.

As of today, Firefox can no longer connect anywhere. I had to use Chrome to post this bug report.

No matter where I try to connect, it fails with the following error:

Secure Connection Failed

An error occurred during a connection to gmail.com. security library: received bad data.

Error code: SEC_ERROR_BAD_DATA

I have recently upgraded to windows 11. After this upgrade, I am facing connection issue in the firefox. Generally, I keep open my Office Gmail Account till my office hours around 8 hrs daily. After the opening the mail it runs as usual, but after ten to fifteen minutes it shows connection error. It continues showing the same error for the whole day. While I tried this things with the other websites, it shows same error for other websites also. The same thing I have tried in Google Chrome browser, there is no such kind of errors or difficulties are found. Kindly guide me further or please update the same.

Today is the day I cannot use Firefox anymore. It keeps on blocking webservers in my local network because of a self-signed certificate.

It is a shame, I have been a loyal Firefox user since Netscape. Today marks the beginning of the end of this journey. A pitty.

So, Chrome it is from now on.

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?

I am repeatedly getting the SECURE CONNECTION FAILED error only for Google-related sites like Youtube, Gmail and Google search. I've to then close Firefox and immediately open it again to see those sites again.

This is the Error: Secure Connection Failed An error occurred during a connection to www.google.com. SSL peer was not expecting a handshake message it received. Error code: SSL_ERROR_HANDSHAKE_UNEXPECTED_ALERT

&

"Secure Connection Failed An error occurred during a connection to www.youtube.com. PR_CONNECT_ABORTED_ERROR"

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.

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

I have since a few weeks errorcodes showing up at my screen whenever i want to visit a website where videocontent is to see( like if you want to visit reddit and watch a video or something like that).I´ve didn´t do or didn´t visit anything special when it came up, it just came and now its there.I´ve also tried different things from the help articles that could solve the problem, didn´t do anything. It says in its message "secure connection failed". The problem is also on every browser, not only on firefox

I hope someone can help me with this problem. I own the domain "cpaaffiliatesnetwork.com" and the site serves as my business site and access to my business network platform. The site is SSL secured and the SSL certificate was renewed in February 2021 for 1 year. Since the SSL renewal, I started having issues accessing the site from any browsers installed on this computer (Edge, Firefox & Chrome). I have now managed to fix the display issue in both Edge & Chrome through clearing cache / history, BUT, I have tried the same with FF with no success. I have also tried uninstalling and reinstalling Firefox, but, still receive the error below for any attempt to access the site: Secure Connection Failed

An error occurred during a connection to www.cpaaffiliatesnetwork.com. Peer’s Certificate has been revoked.

Error code: SEC_ERROR_REVOKED_CERTIFICATE

   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.

All external people i have asked to check the site have confirmed it works fine for them, but, it will not work for me. Hoping someone has a suggestion many thanks in advance :)

Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Kaspersky support has been assisting but no solutions as yet. Any help from Mozilla is appreciated. This has been going on for 4 days now.
