What BrowserStack features are not available on Firefox 57+?

With the release of Firefox 57+, our existing Browserstack extension has stopped working as Mozilla has transitioned into a full extensions model and dropped support for few apis (eg – sockets api) that are needed to support the following Browserstack features.

  • Mobile Dev Tools
  • 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.
