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.
