Tamper Data for FF Quantum

## Tamper Data for FF Quantum

The original Tamper Data no longer works in FF 57+.

This is a re-write that works in FF 57+, however, the webRequest API doesn’t currently support changing request body parameters. There are tickets open for both Firefox and Chrome so hopefully it will be resolved sooner than later, but for now this is still very useful for other things:

  • Monitoring live requests
  • Editing headers on live requests
  • Canceling live requests
  • Redirecting live requests

Installing from source (Development)

1) Download and unpack the source code. 2) Navigate to about:debugging. 3) Click the button to add a temporary extention. 4) Select the manifest.json file and hit OK.

It will automatically uninstall when you close the browser.

Install from the Official Add-ons Page

Usage

Once installed you will see a blue cloud button in the toolbar, to the left of the URL bar. Click that to start tampering.
