Firefox Support Forum

I can log into mozilla and edge browser on this pc. I can log into mozilla on Android app. I CANNOT LOG INTO MOZILLA ON THE MOZILLA BROWSER ON PC.

I have changed my password multiple times and had to use 2 backup codes all to install google authentification app on my phone. I cannot do this from my edge browser. I also have tried multiple times to install the vpn but that hasn't been successful either.

Mozilla needs a video tutorial on how to do this successfully especially when you don't have a QR code. Im just glad that i saved my backup codes.

Hi. I'm worinkg on my own userscript in tampermonkey and need to parse all my unvisited links. Is there any way to make visisted links accesible via JS only for my browser or certain domain?

I have a new laptop. I want to load up my account but because my password is wrong, I can't. What can I do? When I try to change my password, I'm told it's the wrong password.

I am just PO'd the latest update to windows broke my browser and I can't reach my internal CA sites because now my browser does not trust them. What a bunch of BS! I don't want to hear about time and all this other happy horse crap, that is not the issue the update is the issue. I got on a linux box and I can reach it just fine. My internal ESXI Lab I cannot connect to with the same issue. I did the security exception setting from true to false and that didn't fix. Just upsets me to no end when vendors do crap like this.

This is the error I receive with nothing to accept risk, so I am dead in the water until you fix this. Does the same with VMWare.

we could not verify the certificate: reason = untrusted

I continue to receive these notices from Bitdefender, what is this about? "firefox.exe attempted to establish a connection relying on an expired certificate to pocklington.mitremedia.com. We blocked the connection to keep your data safe since websites must renew their certificates with a certification authority to stay current, and outdated security certificates represent a risk."

Something in the last few Firefox updates is now preventing me from logging into the admin interface of my home router (Sonicwall TZ570) and wifi access point controller (Unify Cloud Key). I have had these devices for several years and Firefox has always allowed me to make an exception and connect to the "unsecure device. Microsoft Edge is giving me the same problem which started about the same time a couple of weeks ago. I am on the latest version of Windows 10 64bit and Firefox is up to date. The Brave browser still works as it should (see first screenshot), but Firefox gives me the "we could not verify the certificate: reason = untrusted" error with no way around it (see second screenshot). I do not have HTTPS Only Mode enabled (see last screenshot) and I don't see any other security setting that should affect this.

This is my home, not a business and I do not have a domain nor a SSL certificate and I should not need one.

Any help will be greatly appreciated. Thanks!

我原来有一个mozilla账户，于 ⁨8/27/2022⁩注册，邮箱是934101587@qq.com,我9/30/2023想在firefox android登录这个账户，用934101587@qq.com，但是却注册了一个新的账户，无法登录我原来的账户，我现在的诉求是，恢复我原来的旧帐户，不需要新账户

"I used to have a Mozilla account, registered on August 27, 2022, with the email address 934101587@qq.com. On September 30, 2023, I tried to log in to this account on Firefox Android using 934101587@qq.com, but inadvertently created a new account. I am unable to access my original account. My current request is to recover my old account; I do not need the new account."

I want to use my 'esmail.hematdoost@gmail.com' instead of current 'hematdoostemail@gmail.com' on my firefox account, but it says that this account has already been confirmed by another user and it has a data breach, apparently on linkedin. I do not understand. both emails belong to me but I cannot use it as secondary email on my firefox!?

Im trying to login into web.newton.co When I click the FingerPrint or Face recognition option Use fingerprint or face recognition to login

Press the button below and follow your browser's steps to log in. I get asked for my PIN. I clicked the option "I forgot my PIN (see screen shot) i get the You Can Reset your pin. it's instructing me to go to Settings/Accounts/Signin Options in Firefox.

But when I go to Settings in FF I see no such a thing...thoughts? Rob

I'm looking for a way to disable the file dialog popup that appears when a user clicks on, for instance, an "Upload File" button on a website.

In Google Chrome, we achieve this by setting the "AllowFileSelectionDialogs" policy to 0 in the registry. Unfortunately, it seems that Firefox does not offer a similar functionality. The operating system will be Windows 10.

Is there any way to achieve this in Firefox?

Hi!

When I open Tools > Browser Tools > Browser Toolbox (Ctrl + Alt + Shift + I) and then go to Network tab then I see browser requests. When I right click image and then choose Copy Image it makes HEAD request to server. And then based on that result seems decide how to copy this image. For example if server responds with 403 to this head request I can still paste copied image to MS paint for example. But I can not paste such images to websites. Such as Yandex reverse image search for example.

Why does firefox behave like that and how to disable it?

To investigate the issue her is a sample clipboard event handler that can take image from clipboard: https://pastebin.com/KNKfPGcy

If HEAD request gets 403 response then this clipboard code will cause the following to be posted instead of image: <Error>AccessDenied<Message>Access Denied</Message><RequestId>6HRMZAKJPFCNZ6QS</RequestId><HostId>ANuZElpxuSerm5iGttCRay/SCAaDuc3Qv1WPxJGHQRJqsGISjyxxG68EFtw9xHDdgnmqtuAZqsg=</HostId></Error>

This situation can happen for example when I open image on new tab and then the server removes image or link gets expired and then I want to copy this image. It causes annoyance where when I want to paste it to some other web site I first have to paste it in MS Paint and then select all and copy in MS paint to finally get image that I can freely paste everywhere.

Seems like this is some deliberately made user hostile behavior in Firefox. How can I disable it? And besides, isn't it a privacy concern when every time I click Copy Image server is notified? I mean someone else should not know that I am about to copy their image.

I was listening to Pandorda and the music spontaneously stopped. The following message was displayed:

Secure Connection Failed

An error occurred during a connection to www.pandora.com. PR_CONNECT_RESET_ERROR

Error code: PR_CONNECT_RESET_ERROR

   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.

As a test, I switched over to Chrome and it is fully operational. I prefer to use Firefox, but it now rejects all secure websites. Help, please.

Thank you, Ron Kinder

Though i did not log into any sites recentl, the status for all my saved logins indicate they were last used either yesterday or the day before. How can this be? Have they been compromised?

Hello and great work so far Firefox team!

Currently, Firefox can be used in Windows from the command line to open any URL (start firefox www.google.com). Since any browser is expected to have Internet access to any website or IP address, this is a real security concern in case of default deny security for firewall outbound traffic.

Here is a hacker scenario: The PC has a list of whitelist applications allowed to connect to the Internet. This prevents lots of malware from connecting to their remote servers. However, malware can bypass that by listening on localhost and requesting Firefox to open the remote server. This way the malware sends and receives data with the server using Firefox after requesting an URL with the malware local port specified as query parameter.

This can be avoided with a special about:config option that completely disables command line processing. I don't know if that's entirely possible, but preventing Firefox to start URLs from command line or explicitly requesting Internet access for static HTML files should be enough.

Note: I use NoScript and that helps in this case, but it is not a bullet proof solution. It may be possible that one of the CDN I have allowed gets hacked with malicious JavaScript. If the malware is already on the PC, it can connect to the remote server using the hacked CDN that is allowed in NoScript. This is a two piece attack, but I still think that using Firefox to access to random URL from command line is dangerous and should have an option to be turned off.

Hello Team,

I have installed Smart Card Minidriver on Windows Intel and installed firefox 64 bit version intel based. Mutual TLS is working as expected with Minidriver (Microsoft Base Smart Card Cryptographic Service Provider). Tried to use PKCS#11 dll and it is also working.

In the same way,

I have installed Smart Card Minidriver on Windows ARM64 and installed firefox ARM64 bit version ARM based. Mutual TLS is not working as expected with Minidriver (Microsoft Base Smart Card Cryptographic Service Provider). But when tried to use PKCS#11 dll and it is working.

I have questions here:

Firefox ARM64 on Windows ARM is not working mutual TLS with Microsoft Base Smart Card Cryptographic, Service Provider, Is this supported?
