How to Enable WebRTC in Your Web Browser

If you would like to host webinars, video conferences or online meetings, you will most likely be unable to go without WebRTC enabled in your web browser. The majority of webinar platforms use this technology. Today, we are going to share several ways of allowing it if, for whatever reason, it appears to be off.

What is WebRTC and why is it necessary?

WebRTC (Real-Time Communication) is a technology that transmits audio and video between mobile phone apps and web browsers. If WebRTC is disabled in your web browser, the latter will not be able to transmit audio and video from you, which in turn means you will not be able to present at a webinar or a video conference.

Usually, this technology is enabled by default, and you don’t have to do anything to join the broadcasting. Yet, sometimes you might find yourself in a situation when administration prohibits using WebRTC, or there are special extensions installed in your web browser that block the technology.

Further, we will show how to enable WebRTC technology in some popular web browsers.

How to enable WebRTC?

Google Chrome

Check if there are any plugins installed in Chrome that are blocking WebRTC. Some examples could be WebRTC Leak Prevent, WebRTC Control, Easy WebRTC Block, WebRTC Network Limiter and more. To do so, in the menu, select More Tools, and then proceed to the Extensions tab.

In the list of extensions, locate the ones mentioned above. Deactivate them for the period of the webinar or uninstall them completely in case you no longer need them.

In Opera, WebRTC can be enabled in two ways: with the help of an extension or in the settings.

First of all, you need to find the extensions that disable the WebRTC technology. For this purpose, select the View tab in the web browser menu and click on Show Extensions in the dropdown list.

opera show

Search for all extensions containing the word WebRTC (WebRTC Leak Prevent, WebRTC Control, Easy WebRTC Block, WebRTC Network Limiter). Disable or uninstall them.

opera disable

To enable WebRTC in the web browser settings, hover over the name Opera in the top left corner and open Preferences.

opera preferences

Now, type “WebRTC” in the search field and enable the first option in the resulting list.

Now WebRTC is enabled and you can present at a webinar.

What if enabling WebRTC is unsuccessful?

You have tried everything and still, no luck enabling WebRTC? It happens. Sometimes it is next to impossible to recognize the plugin blocking the technology. It can even be that your system administrator blocks WebRTC.

Nevertheless, you will still be able to hold a webinar. Namely, for such cases, we offer an alternative technology. It is a special plugin in the webinar room that needs to be installed on your computer. Read more on how to download, install and use it here.
