I apologize if this has already been brought up.

It seems that the browser has access to a list of my media devices, without needing any special permissions. On Am I Unique, they can grab the unique ID of my builtin macbook camera & microphone. I believe the culprit is MediaDevices.enumerateDevices(). I do have privacy.resistFingerprinting set to True.

Perhaps you could put it behind a permission request, like MediaDevices.getUserMedia()?

Thank you for your time.

I am using Opensuse 15.0 and also 15.1. Haven't made a complete move over yet. There is a recurring situation when 4GB rx and 4GB tx movement that I cannot account for hits my 15.0 about once a month. Today it happened again. Using vnstat, I found it happened between 10.00 - 11.00. :

Searched the cookies, one site i cannot recognize came out; "consensu.org". Did a search, there were several, example: https://cmp.teads.mgr.consensu.org/index.html, that served blank pages in firefox. Is there anything odd here? Is there a way I can extract all the cookies with date & time so that I can check against previous occurrences of the 4GB data movements (I have a few records).

Unlike some people who don't want to see the extension name in the address bar, I want to see the *entire* extension name. Threat model: one of my extensions gets a rogue update and puts up a screen that looks just like a screen (e.g., the login page) of another extension (e.g., my password manager).

When the extension name is too long, Firefox currently displays: Extension... <last word of extension name>

To be secure I currently need to click on the above so that it expands, in order to verify it's the correct extension.

Can this be done in CSS, or would a feature change be needed to Firefox?

Hi Team,

We are facing issue while exporting documents from our portal which is embedded into an iframe of some external portal.

We see the following error in the console :

Content Security Policy: The page’s settings blocked the loading of a resource at blob:https://abc.def.com/1gg3810-ae25-42ae-ghghb-123456789 (“frame-src”).

This issue comes only in firefox. We are able to export documents in other browsers. We think that the problem comes due to the portal is embedded into an iframe. when we execute the download URL in a separate tab, it allows to download the document.

We are using below CSP policy :

default-src * blob: 'self' 'unsafe-eval' 'unsafe-inline'; font-src * data:; img-src * data:; frame-src * blob: data: 'self'; object-src *

Thanks

Hi, so i found this excellent article https://support.mozilla.org/en-US/kb/install-firefox-linux and I unzipped/extracted the firefox-77.0.1.tar.bz2 file.

By the way, am glad to know I don't have to compile it. Tis a relief :)

So the article above says to check this list @ https://www.mozilla.org/en-US/firefox/77.0.1/system-requirements/#software-requirements for "required libraries". I am really good at the command line except for checking library dependencies. :/

Last link shows these 5:

  • Bulleted list item GTK+ 3.4 or higher
   * Bulleted list item    GLib 2.22 or higher
   * Bulleted list item    Pango 1.22 or higher
   * Bulleted list item    X.Org 1.0 or higher (1.7 or higher is recommended)
  • Bulleted list item libstdc++ 4.7 or higher

My fear is i'll have to search around a while for the exact package name since sometimes capitalization and dashes matter when using apt, aptitude, or synaptic.

Here's what I am trying so far. I started with libstdc++ since that's all lower case. ++++++++++++++++++++++++++++ $ apt list | grep libstdc++ | grep -v unstable ... ... (super long list of lots of different libstdc++) ... libstdc++6/stable 8.3.0-6 i386 ++++++++++++++++++++++++++++ So since that ends with version 8.3 and that's higher than the "4.7 or higher" in the official list above, then I'm good. (By the way, just a plain `apt list libstdc++` returned no results.)

And substituting the word 'pango' in the above command gives a similarly long list that looks good, i think. Same with 'gtk3', 'glib2', and 'xorg'.

Oh, i think i've answered my own question :) but maybe went the scenic route with my command since i did not know the exact package names.

Anybody have a faster way of checking for these? Pretty please? :)

P.S. By the way, I'm using Debian but in my experience it wouldn't matter if i was using Arch or even one of the BSD's right now. Yes, tools are slightly different like apt/dpkg, or ports but am mostly curious for what exact package names to search for to save me time. :)

Thanks, you all rock. Love the community here though,

I am trying to install the OpenH264 Add-in from the Add-ins section on a Firefox 68.9.0-esr.1 version running Raspbian "Buster" which is up to date. Even though the Firefox is installed correctly and connected to the internet this add-in keeps displaying a warning or info sticker saying "OpenH264 Video CODEC is provided by Cisco Systems, Inc - Will be installed shortly.

I have waited hours for it to start to download, tried restarting Firefox, even rebooted the entire system will no success.

Even tried to download it manually from the OpenH264 site but could not find a .xpi or .jar file to plug in.

Can anyone help as to how I can make this Add-in download happen inside Firefox please?

OpenGL and WebGL hardware acceleration not working on Debian Firefox with Intel 915GM

Dear Mozilla Supporters,

I am having issues with OpenGL and WebGL support on an older 32 bit Pentium M machine using the latest Firefox 77.0.1 and Debian 10.4 on LXQt. - GPU is Intel 915GM - kernel support is enabled - correct firmware and mesa drivers available for OpenGL 1.4, OpenGL ES 2.0 - X11 correctly initialises DRI and DRI2 with kms and SNA

Firefox about:support shows: - blacklisted OPenGL and WebGL with FEATURE_FAILURE_OPENGL_1 - WebGL 1 Driver Renderer WebGL creation failed:

  • Refused to create native OpenGL context because of blacklist entry: FEATURE_FAILURE_OPENGL_1
  • Exhausted GL driver options.

WebGL 2 Driver Renderer WebGL creation failed:

  • Refused to create WebGL2 context because of blacklist entry: FEATURE_FAILURE_OPENGL_1

WEBRENDER opt-in by default: WebRender is an opt-in feature WEBRENDER_QUALIFIED blacklisted by env: No qualified hardware WEBRENDER_COMPOSITOR disabled by default: Disabled by default blacklisted by env: Blacklisted by gfxInfo unavailable by runtime: No DirectComposition usage WEBRENDER_ANGLE opt-in by default: WebRender ANGLE is an opt-in feature WEBRENDER_DCOMP_PRESENT opt-in by default: WebRender DirectComposition is an opt-in feature OMTP broken by runtime: OMTP is not supported on 32-bit with <= 2 cores WEBGPU disabled by default: Disabled by default blocked by runtime: WebGPU can only be enabled in nightly

I tried many different Firefox config combinations with force_acceleration, as well as X11 with UXA, without success. I tested OpenGL support in native X11 with glxinfo and glxdemo, and hardware accelleration does work.

I believe this worked in the past without issues, I have been using the same machine on older Lubuntu and recently decided to upgrade to the latest Debian eqivalent.

Any ideas why Firefox does not see and use the OpenGL accelleration available in X11?

I recently bought a graphic tablet (https://www.trust.com/en/product/21794-panora-widescreen-graphic-tablet), and it works flawlessly outside of firefox. However, when holding BigBlueButton lectuers, I need to use it within firefox, which doesn't seem to work. At first I thought it was an issue with BigBlueButton, but now I tried other websites (limnu, cocreate, etc.), and they all have the same problem:

Whenever I move the pen on my graphic tablet, only the first and last 'points' are recognized. Is there a way to increase firefox's refresh rate for mouse clicks? Or is there any other solution?

I'm using firefox 68.9.0esr, 64-bit on windows 10.

Hi folks,

I have endured the sync problem for months. Today I struggled for solving it.

I have a Firefox 68.0.1 esr manual installation on Ubuntu 16.04. The sync worked when I signed in the first time. But the bookmark can not longer be updated afterwards.

If I add or delete a bookmark on my Firefox 68.0.1 esr on Windows 10, the change will not be updated to the Linux version. And vice versa.

On the Linux, I tried to disconnect my account (in the preference about:preferences?entrypoint=fxa_app_menu#sync ). I click "Disconnect" and "Just Disconnect" in the prompt, but the account is still logged in.

Another way I tried is to have a fresh new installation of Firefox 68.9 esr. Then I was asked to sign in again. After typing the password, the new bookmarks were updated. But If I make further changes on the other devices, these changes will not be sync to Linux. And I can't disconnect the account on Linux.

It looks like a new install, which resetting the login process can temporarily solve the problem.

Here is the content of the sync-log file. Can you see what is broken? Thanks in advance.

We have a server running Debian Buster with Janus and Asterisk installed using the standard Debian packages. Using the standard Janus test page to make calls through our server via the Websockets interface, we have no problems with any of the Firefox 68esr browsers, but after upgrading to the latest 78esr browser, we have no audio after the call connects if we initiate the call from Windows 10. Using Linux or Mac 78esr (or any OS with Chrome) to initiate the call audio is working, even if the answering browser is 78esr on Windows 10.

Looking in the Asterisk and Janus logs for working and silent calls, they appear identical (opus codec selected in all cases), and there are no errors in the Web Console after upgrading adapter.js to 7.4.0.

Is there a known problem with websockets and 78esr?
