By using the last version of Firefox (74.0) when visiting a website with security connection I got the following error : "Secure Connection Failed An error occurred during a connection to .............. 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." With the previous versions of Firefox there was no such problem and I could visit the above website. So, please inform me what happened with ver. 74.0 ? By ver. 74.0 is no more supported some older security protocols which might have the above website, or this is a bug by the new ver. 74.0 ? Please inform me how this issue can be fixed ?

Can I enable pop-ups for an entire domain, or only individual websites within the domain?

I want to enable pop-ups within my company e.g. widgets.com My company has many individual websites e.g. https://text.widgets.com, https://slider.widgets.com, https://frob.corp.widgets.com It becomes tiresome to have to white-list each of them in the "Allowed Websites - Pop-ups" configuration. Is there a way to enable all of websites in a domain with a single configuration specification? Including subdomain sites? Perhaps via something akin to (regex) https://.*\.widgets\.com

How can I enable the microphone? The second method does not work for me

Firefox-Version: 74.0 (64-Bit) Operating system: Xubuntu 18.04

I want to participate in meetings with Teamviewer or in https://meet.jit.si. I want to enable my mike in the browser for that purpose.

I read the hint

https://support.mozilla.org/en…ng-microphone-permissions

but that does not work for me: After entering the URL into the dialogue,e.g.. https://meet.jit.si I am supposed to press ENTER. But then nothing happens!

I expect the entered URL to be added to the list below after pressing ENTER (this list was empty before in my case).

When I want to participate in such a meeting, I get a question whether I would allow the microphone to be used. Even if I allow it, meet.jit.si tells me that it could not use the microphone for an unspecified reason.

In the browser when trying to use such a connection, to the left of the URL there is a closed lock symbol and a red microphone symbol.

I have checked if the microphone works: I can record something with it using Audacity and if I activate the Pulseaudio-volume control I see a level indicator which reacts on sound heard by my microphone.

What must I do to enable the microphone for TeamViewer or other net meetings?

Hello.

I have a question. In which folder is my Firefox browsing history stored, please?

I ask because I want to create a kind of "browsing diary", and tried to export my browsing history via Mozilla History View. But it couldn't find the folder with my browsing history.

I'm working from a WINDOWS 7 64 Bit computer, and my Firefox version is Firefox 74.0 64 Bit. With those specifications, where do I look for the folder with my browsing history?

Thanks in advance for any answers, and have a great Sunday!

Hi there,

We have a weird problem with firefox only (not this problem with other web browser like Chrome, Ie or Edge). The problem is that we cannot browse this website at the same time. No problem to browse one website, but going on the seconde one and you will get on 404 error.

Not Found ________________________________________ HTTP Error 404. The requested resource is not found.

Same error for 3 others.

Just waiting few minutes (at least 5min), refresh the second website, it’s working coming back on the first tab (with the first website), refresh and you get the error 404.

This problem occurs only when we are using IPV6 connexion on an HTTPS websites (only on some of ours web sites (https://www.ticpharma.com/home.php, https://www.techopital.com/ https://www.gerontonews.com, https://www.ticsante.com/home.php and https://www.apminternational.fr/). These 5 website sharing the same SSL certificats. It’s a multi domain SSL certificats provide by Gandi.net.

No problem when we use the Firefox PRIVATE windows. No problem when we browse theses websites in http and IPV6. No problem when we browse theses websites in httpS and IPV4. No problem with other browser in httpS and IPV6.

So only problem with Firefox, in IPV6 and HPPS. This problem occurs on multiple computers, with diffrent Anti-Virus, from different location, for different network and ISP provider. So I guess there is a bug somewhere in firefox.

Thanks for your help. Regards.

Trying to set up HTML5 peer-peer video conferencing. Its working on Chrome but not Firefox. I have looked at all the available solutions. I have reinstalled firefox; I have checked that media.windows.foundation is set to "true"; I have checked in "safe mode".

This challenge is an issue which occurs 90% of the time. I have yet to assess what conditions occur when html5 video is finally displayed. I can only say that display only occurrred once today and that was when I first inspected the site this morning.

This situation is occurring both in Firefox and the developer edition. Firefox is latest edition and there are no plugins

Any suggestions?

Firefox using "TLSv1 Record Layer" possibly makes company portal inaccessible

Since we switched to a new company portal ("intranet"), I can no longer use Firefox to access it. Chrome and Internet Exploder both work fine (on the very same machine, same network, etc!).

The error message I get is:

An error occurred during a connection to <hostname>. 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.

Somehow this sounds like a certificate verification problem, but if that was really a problem, Firefox wouldn't continue starting the TLS handshake, right? But it does...

I used Wireshark to do network traces, and I can see that after the initial "client hello" the portal web server resets the connection. When I compared the snoop to one captured for Chrome, I noticed that the "client hello" Firefox sends uses a "TLSv1 Record Layer" in the "Client Hello," while Chrome uses a "TLSv1.2 Record Layer" in the "Client Hello."

I set "security.tls.version.min" to "2" already, but that didn't help.

I later also noticed that Chrome offers two TLS_RSA_WITH_AES_xxx_GCM_SHAxxx crypto suites, while Firefox doesn't.

My guess is that one of the above observations is likely the reason why Firefox can't connect.

Does that sound plausible to you? Why the difference in the TLS record layer? Why doesn't Firefox the above cypto suites? Are they considered insecure?

(Before you ask, unfortunately I can't give the host name to our portal, sorry.)

Many thanks for your help, this is really annoying me...

Kr,

Ralf

I have a question regarding PWA support on Firefox desktop. I am not sure how to frame this correctly, but I hope I am able to list the problem statement.

Basically, I plan to migrate my existing mobile and desktop website to single PWA based responsive website. Right now, I have mobile website which is a PWA, and a desktop website. Goal is to have a single PWA based responsive website for both mobile and desktop platform. However, I want to make sure the proposed website will work with Firefox desktop. From what I could find Firefox doesn't support option to install PWA as an app with it's own shortcut as it is possible in Chrome. But I want to make sure it supports rest of the features of PWA, and website still works correctly in terms of UI and experience as in case when it is accessed from Chrome browser.

Appreciate a response on this. In case you require more clarity on the problem statement, do let me know.

The sites on which this is occurring include those with multiple, frequently refreshing ads and other content: BBC News, Discover Magazine blogs, Boston Globe newspaper. Over a fairly short time, e.g., 20 minutes or so, physical memory usage as reported by Task Manager climbs to over 95%. Closing the tab for the offending web site almost always immediately drops memory usage to under 40%. If that fails, closing and then reopening Firefox fixes the problem. Please note that this did not occur with the previously installed version. I have Firefox set to automatically update.

Hi,

I am trying to configure PKI based authentication and encryption system in my organization using Hardware token. I was able to install my hardware token feitan ePass2003 Auto in privacy->security device. I am able to see my certificates under view certificate after entering my password for private key. After research on internet, came to know that Applet based client authentication is obsolete and hence i have configure my token in Firefox. The next step i.e Authentication page is where i have got stuck up. Can any one please give details guide on how to use cryptoken operation(challenge & signing) and access to token in JavaScript at client side login page. I could not get hold of any library of java script for access to token through Firefox. Any guidance is highly appreciated.

Thanks

I've found other posts on the same error but not a resolution that works for me. I know Firefox updated a few days ago but it didn't start then, and I haven't changed or updated anything else. (Everything is up to date)
