Jitsi Meet Firefox

Amid the pandemic, Mozilla is educating consumers about popular video apps’ privacy and security features and flaws

Using Firefox 47, calls with Jitsi Meet appear to reliably fail. Grant access to microphone 3. Grant access to camera At this point, note the lack of self-view. I am able to use Jitsi Meet with Firefox 74 (64 bit) on Linux Mint 17.3. The only thing which seems not to work is the image blur option but that is not a major concern. The video and sound quality are just as good as achieved using Chromium and I much prefer Firefox generally. Michael-j April 1, 2020, 4:53pm #12. If you are running Jitsi Meet on a server behind NAT, forward the ports on your router to your server's IP address. Note: if participants cannot see or hear each other, double check your firewall / NAT rules.

[Update, April 29: Following the publication of Mozilla’s guide, Discord updated their password requirements. As a result, Discord now meets Mozilla’s Minimum Security Guidelines.Learn more here.]

Right now, a record number of people are using video call apps to conduct business, teach classes, meet with doctors, and stay in touch with friends. It’s more important than ever for this technology to be trustworthy — but some apps don’t always respect users’ privacy and security.

Jitsi meet firefox extension

So today, Mozilla ispublishing a guide to popular video call apps’ privacy and security features and flaws. Consumers can use this information to choose apps they’re comfortable with — and to avoid ones they find creepy.

This work is an addition to Mozilla’s annual *Privacy Not Included guide, which rates popular connected products’ privacy and security features during the holiday shopping season. We created this new edition based on reader demand: Last month, we asked our community what information they need most right now, and an overwhelming number asked for privacy and security insights into video call apps.

In this latest installment, Mozilla researchers dug into 15 apps, from Zoom and Skype to HouseParty and Discord. Our researchers answered important questions like: Does the app share user data — and if so, with whom? Are users alerted when meetings are recorded? Is the app compliant with U.S. medical privacy laws? And many more.

Researchers also determined whether or not apps meet Mozilla’s Minimum Security Standards. These five guidelines include: Using encryption; providing security updates; requiring strong passwords; managing vulnerabilities; and featuring a privacy policy.

In total, 12 apps met Mozilla’s Minimum Security Standards: Zoom, Google Duo/HangoutsMeet, Apple FaceTime, Skype, Facebook Messenger, WhatsApp, Jitsi Meet, Signal, Microsoft Teams, BlueJeans, GoTo Meeting, and Cisco WebEx.

Three products did not meet Mozilla’s Minimum Security Standards: Houseparty, Discord, and Doxy.me.

The Minimum Security Standards are just one layer of our guide, however. What else did our research uncover?

  • Competition is fierce in the video call app space — which is good news for consumers
    • Zoom has been criticized for privacy and security flaws. Because there are many other video call app options out there, Zoom acted quickly to address concerns. This isn’t something we necessarily see with companies like Facebook, which don’t have a true competitor
    • When one company adds a feature that users really like, other companies are quick to follow. For example, Zoom and Google Hangouts popularized one-click links to get into meetings, and Skype recently added the feature. And just last week Facebook added Messenger Rooms, which allows up to 50 people to chat at once in Messenger for as long as they want
  • All apps use some form of encryption, but not all encryption is equal
    • All the video call apps in our guide offer some form of encryption. But not all apps use the holy grail: end-to-end encryption. End-to-end encryption means only those who are part of the call can access the call’s content. No one can listen in, not even the company. Other apps use client-to-server encryption, similar to what your browser does for HTTPS web sites. As your data moves from one point to another, it’s unreadable. Though unlike end-to-end encryption, once your data lands on a company’s servers, it then becomes readable
  • Video call apps targeting businesses have a different set of features than video call apps targeting everyday use
    • This may seem obvious. But it’s important. Video call apps like FaceTime, Google Duo, Signal, and Houseparty have a very different set of video chat features and ease of use than business-oriented apps such as Zoom, BlueJeans, GoToMeeting, Microsoft Teams, and Cisco Webex. Consumers who want something simple may want to skip the B2B apps. Business users who want a fuller set of features and have money to pay may look to business-focused apps
  • There is a diverse range of risks
    • Facebook doesn’t use the content of your messages for ad targeting. But it does collect a lot of other personal information. It collects name, email, location, geolocations on photos you upload, information about your contacts, information about you other people might share, and even any information it can gather about you when you use the camera feature. Facebook says it can use all this personal information to target you with ads. It also shares information with a large number of third-party partners including advertisers, vendors, academic researchers, and analytic services
    • WhatsApp is solid for video chat, and gets bonus points for using end-to-end encryption on users’ messages and calls. However, it is sullied by an overwhelming amount of misinformation on the platform. Especially during this global pandemic, conspiracies and fake news are being spread across WhatsApp
    • Houseparty is admittedly more fun than some others on our list, but it comes with its own problems. Houseparty appears to be a personal data vacuum (though kudos to their privacy policy for being easy to read to tell you that)
    • Discord collects more information than we’re comfortable with. For example, it collects information on your contacts if you link your social media accounts. And then there’s the toxicity: dig deep enough and you’ll find some pretty troubling corners of Discord that are known for misogyny, racial harrassment, and human trafficking
  • Good news: Many apps provide admirable privacy and security features
    • All apps with a built-in recording feature alert participants when recording occurs
    • On most apps, hosts have the ability to set rules, like who can unmute and who can share their screen — meaning accidents and trolls can quickly be dealt with
    • The two open-source apps in the guide — Jitsi Meet and Signal — have strong privacy protections

You can use Jitsi Meet API to create Jitsi Meet video conferences with a custom GUI.

Installation

To embed Jitsi Meet API in your application you need to add Jitsi Meet API library

Now you can access Jitsi Meet API trough the JitsiMeetJS global object.

Getting Started

  1. The first thing you must do in order to use Jitsi Meet API is to initialize JitsiMeetJS object:
  1. Then you must create the connection object:
  1. Now we can attach some listeners to the connection object and establish the server connection:
  1. After you receive the CONNECTION_ESTABLISHED event you are to create the JitsiConference object andalso you may want to attach listeners for conference events (we are going to add handlers for remote track, conference joined, etc. ):
  1. You also may want to get your local tracks from the camera and microphone:

NOTE: Adding listeners and creating local streams are not mandatory steps.

  1. Then you are ready to create / join a conference :

After that step you are in the conference. Now you can continue with adding some code that will handle the events and manage the conference.

Components

Jitsi Meet API has the following components:

  • JitsiMeetJS

  • JitsiConnection

  • JitsiConference

  • JitsiTrack

  • JitsiTrackError

Usage

Firefox

JaaS customers, please checkout this example: https://github.com/saghul/sandbox-html/tree/main/jaas-ljm. Live: https://bettercallsaghul.com/sandbox-html/jaas-ljm/

JitsiMeetJS

You can access the following methods and objects trough JitsiMeetJS object.

  • JitsiMeetJS.init(options) - this method initialized Jitsi Meet API.The options parameter is JS object with the following properties:

    • useIPv6 - boolean property
    • disableAudioLevels - boolean property. Enables/disables audio levels.
    • disableSimulcast - boolean property. Enables/disables simulcast.
    • enableWindowOnErrorHandler - boolean property (default false). Enables/disables attaching global onerror handler (window.onerror).
    • disableThirdPartyRequests - if true - callstats will be disabled and the callstats API won't be included.
    • enableAnalyticsLogging - boolean property (default false). Enables/disables analytics logging.
    • externalStorage - Object that implements the Storage interface. If specified this object will be used for storing data instead of localStorage.
    • callStatsCustomScriptUrl - (optional) custom url to access callstats client script
    • disableRtx - (optional) boolean property (default to false). Enables/disable the use of RTX.
    • disabledCodec - the mime type of the code that should not be negotiated on the peerconnection.
    • preferredCodec - the mime type of the codec that needs to be made the preferred codec for the connection.
    • useTurnUdp - boolean property (default false). Enables use of turn over udp for jvb. It is disabled because not very useful (if the client can use udp, it likely can connect to jvb directly over udp too; but it can be useful to still enable udp turn when an udp turn is known to be whitelisted on a network)
    • disableH264 - DEPRECATED. Use disabledCodec instead.
    • preferH264 - DEPRECATED. Use preferredCodec instead.
  • JitsiMeetJS.JitsiConnection - the JitsiConnection constructor. You can use that to create new server connection.

  • JitsiMeetJS.setLogLevel - changes the log level for the library. For example to have only error messages you should do:

Jitsi Meet Linux

  • JitsiMeetJS.createLocalTracks(options) - Creates the media tracks and returns them trough Promise object. If rejected, passes JitsiTrackError instance to catch block.

    • options - JS object with configuration options for the local media tracks. You can change the following properties there:
      1. devices - array with the devices - 'desktop', 'video' and 'audio' that will be passed to GUM. If that property is not set GUM will try to get all available devices.
      2. resolution - the prefered resolution for the local video.
      3. constraints - the prefered encoding properties for the created track (replaces 'resolution' in newer releases of browsers)
      4. cameraDeviceId - the deviceID for the video device that is going to be used
      5. micDeviceId - the deviceID for the audio device that is going to be used
      6. minFps - the minimum frame rate for the video stream (passed to GUM)
      7. maxFps - the maximum frame rate for the video stream (passed to GUM)
      8. desktopSharingFrameRate

      10. facingMode - facing mode for a camera (possible values - 'user', 'environment')
      11. firePermissionPromptIsShownEvent - optional boolean parameter. If set to true, JitsiMediaDevicesEvents.PERMISSION_PROMPT_IS_SHOWN will be fired when browser shows gUM permission prompt.
      12. fireSlowPromiseEvent - optional boolean parameter. If set to true, JitsiMediaDevicesEvents.USER_MEDIA_SLOW_PROMISE_TIMEOUT will be fired when browser takes too long to resolve the gUM promise. This event is mutual exclusive with the above JitsiMediaDevicesEvents.PERMISSION_PROMPT_IS_SHOWN event
    • firePermissionPromptIsShownEvent - DEPRECATED. Use options.firePermissionPromptIsShownEvent instead
  • JitsiMeetJS.createTrackVADEmitter(localAudioDeviceId, sampleRate, vadProcessor) - Creates a TrackVADEmitter service that connects an audio track to a VAD (voice activity detection) processor in order to obtain VAD scores for individual PCM audio samples.

    • localAudioDeviceId - The target local audio device.
    • sampleRate - Sample rate at which the emitter will operate. Possible values 256, 512, 1024, 4096, 8192, 16384. Passing other values will default to closes neighbor, i.e. Providing a value of 4096 means that the emitter will process bundles of 4096 PCM samples at a time, higher values mean longer calls, lowers values mean more calls but shorter.
    • vadProcessor - VAD Processors that does the actual compute on a PCM sample.The processor needs to implement the following functions:
      • getSampleLength() - Returns the sample size accepted by calculateAudioFrameVAD.
      • getRequiredPCMFrequency() - Returns the PCM frequency at which the processor operates .i.e. (16KHz, 44.1 KHz etc.)
      • calculateAudioFrameVAD(pcmSample) - Process a 32 float pcm sample of getSampleLength size.

  • JitsiMeetJS.isDesktopSharingEnabled() - returns true if desktop sharing is supported and false otherwise. NOTE: that method can be used after JitsiMeetJS.init(options) is completed otherwise the result will be always null.

  • JitsiMeetJS.getActiveAudioDevice() - goes through all audio devices on the system and returns information about one that is active, i.e. has audio signal. Returns a Promise resolving to an Object with the following structure:

    • deviceId - string containing the device ID of the audio track found as active.
    • deviceLabel - string containing the label of the audio device.

    • isDeviceListAvailable() - returns true if retrieving the device list is supported and false - otherwise
    • isDeviceChangeAvailable(deviceType) - returns true if changing the input (camera / microphone) or output (audio) device is supported and false if not. deviceType is a type of device to change. Undefined or 'input' stands for input devices, 'output' - for audio output devices.
    • enumerateDevices(callback) - returns list of the available devices as a parameter to the callback function. Every device is a MediaDeviceInfo object with the following properties:
      • label - the name of the device
      • kind - 'audioinput', 'videoinput' or 'audiooutput'
      • deviceId - the id of the device
      • groupId - group identifier, two devices have the same group identifier if they belong to the same physical device; for example a monitor with both a built-in camera and microphone

    • getAudioOutputDevice() - returns currently used audio output device id, ' stands for default device.
    • isDevicePermissionGranted(type) - returns a Promise which resolves to true if user granted permission to media devices. type - 'audio', 'video' or undefined. In case of undefined will check if both audio and video permissions were granted.
    • addEventListener(event, handler) - attaches an event handler.
    • removeEventListener(event, handler) - removes an event handler.
  • JitsiMeetJS.events - JS object that contains all events used by the API. You will need that JS object when you try to subscribe for connection or conference events.We have two event types - connection and conference. You can access the events with the following code JitsiMeetJS.events.<event_type>.<event_name>.For example if you want to use the conference event that is fired when somebody leave conference you can use the following code - JitsiMeetJS.events.conference.USER_LEFT.We support the following events:

  • error - original GUM error
  • constraints - GUM constraints object used for the call
  • devices - array of devices requested in GUM call (possible values - 'audio', 'video', 'screen', 'desktop', 'audiooutput')
