If skype web sdk for online 365 purposely blocked Firefox? RRS feed

  • Question

  • I am implementing Skype for Business Web SDK to my project. The incoming call detection is one of the features we used. Unfortunately, the skype web sdk for online 365 blocked the Firefox browser.

    I have looked at the Skype for Business Web SDK general reference carefully. It mentioned that Firefox is one of the supported browsers.

    Also, I tested SkypeWebSDKOnPrem Sample on Firefox which was working perfectly. However, the incoming call detection in SkypeWebSDKOnlineSample didn’t work on Firefox browser but worked on Chrome and Edge. The error message is displayed below.

    Source map error: request failed with status 404

    Resource URL:

    Source Map URL:;

    When I opened SkypeWebSDKOnlineSample to detect incoming call, the source file couldn’t be mapped as shown above. It seems that only Firefox browser is purposely blocked by skype web sdk.

    Please advise any solutions to solve this issue. Any suggestions would be greatly appreciated.
