What BrowserStack features are not available on Firefox 57+?

With release of Firefox 57+, Mozilla has dropped support for BrowserStack's extension along with many other extensions. We have tried to rebuild the Firefox extension well ahead of 57 being released to ensure the experience of our customers is not hampered. We have also connected with Mozilla team on this. But currently Mozilla does not provide a few apis (eg - sockets api) that are needed for us to rebuild the extension. For Chrome, we have built the Chrome app to support following BrowserStack features. Mozilla does not allow porting of this Chrome app. It allows porting of extensions. Hence we cannot port our Chrome app to Firefox.

As a result following BrowserStack features are not available on Firefox 57+ for Live and App Live.

  • Local Testing
  • Mobile Dev Tools
  • Copy-paste
  • Quick Launch

If you are behind a firewall or corporate network and are using Live or App Live on Firefox 57+, you may experience performance issues.

While we are working to fix this, to access all the features of BrowserStack and for better performance, we recommend you to switch to Chrome.
