**Description**  
The virtual background API with video SDK doesn’t seem to be working with firefox even though hardware acceleration is enabled, and it works fine on chromium-based browsers.

**Which Web Video SDK version?**  
Video SDK Version - `1.5.1`  
Firefox Version - `103.0.2`

but maybe something will change in the future

which method do you use to enable SharedArrayBuffer?

Thanks for the confirmation! We currently use Chrome’s Origin trials, are there any workarounds to make it work with Firefox?

Hey @harshita.kanal

Thanks for your feedback.

Virtual background is not supported on Firefox so far. It’s the limitation of the browser, we use WebCodec to achieve the function, but unfortunately, it doesn’t support yet on Firefox.

Thanks  
Vic
