Mozilla Firefox Origin Trials are a way for websites to opt-in to experimental web platform features.
Current Trials
Currently active trials are:
- COEP: credentialless: Enables the `credentialless` value for the `Cross-Origin-Embedder-Policy` header.
- COEP: credentialless is enabled in Firefox Desktop by default since Firefox 119, you only need to request an origin trial if you need it for Firefox Android.
Requesting a trial for your website
In order to request a trial please click here:
That will take you to Bugzilla with an already-prefilled template where you'd need to fill a few details (like trial name, website origin, whether subdomains should be included, and a suggested expiration date / other details if you know them). A token will be given to you in that bug.
Using the trial token
Once you get a reply with a token, you can use them by serving your page with the relevant header:
origin-trial: your-token
O with a meta tag:
<meta http-equiv="origin-trial" content="your-token">
