Overall Status

[In Progress] : Nightly 67 in 3/07/2019

Testing Summary

Scope of testing

The testing will be focus on the results of DevTools Remote Debugging with various devices. USB connection: making sure we can connect to devices, that the basic debugging experience is there and the workflow works. Connecting to network devices: be able to connect to Firefox 66, 67, 68 (there’ll be backward compatibility messages for other versions) In theory you can try to connect to anything, we don’t plan to prevent it but it might not work


Testing will be performed on following devices:

  • Phones
    • [ Sony Xperia Z3 Android 5.1.1]
  • Tablet

  • First test report is sent
  • Please note that this email stands as a test report from “DevTools Remote Debugging” feature on Nightly 67. It is not a formal sign off, as the feature isn't going to ride the Fx67 train and the plan is to ship in Firefox 68. The implementation of this feature is not completed and currently does not require a pre-Beta sign-off.
