The latest Microsoft Edge Canary currently offers Allow and Limit options in Settings for media autoplay, here is how you can re-add the removed “Block” option to Settings in the New Edge browser.
Microsoft is going back and forth on Block option for autoplay media in the Edge Chromium browser. The company first offered limit option via a flag, then pulled it and provided along with Allow and Block options by default in Settings. Recently Redmond Software giant has removed the Block option from Media Autoplay Settings, now allowing to add it back via a flag in edge://flags page in Canary build.
Re-adding the Block option to autoplay media settings in new Microsoft Edge browser
1. Ensure you’re using latest Microsoft Edge Canary build 79.0.308.0 or later
2. Visit edge://flags, search for “block”, in the highlighted search results, for “Show block option in autoplay Settings flag”
3. Select “Enabled” and restart the browser.
Now if you visit edge://settings/content/mediaAutoplay page and click on down arrow next to “Allow”, you’ll notice Block option along with Limit, select it.
Edge is providing this information on how the browser handles autoplaying video or audio on a website if you set any of these options
Allow: All media will automatically play.
Limit: Media will be blocked based on what you’ve blocked in the past.
Block: Media that plays sound will be blocked from automatically playing.
Let me explain what happens a bit more clearly if you choose the third option. Edge then just stops the audio but not the video for autoplay media and the video will continue to play without sound (as we observed). We want Edge to stop autoplay of both audio and video, like Firefox.
