Mozilla WAICT Verifies Web App JavaScript in Nightly
WAICT in Firefox Nightly binds client code to public manifests so browsers reject unlogged JavaScript. This stops compromised servers from silently injecting malicious code into encrypted web apps like Signal. Test it at waict.dev.
WAICT, a new Firefox Nightly prototype, cryptographically binds client-side JavaScript to public manifests so browsers reject unlogged code. For engineers building browser-based E2EE apps like Signal, this closes a critical gap where compromised servers could selectively inject malicious JavaScript to steal keys. Mozilla is collaborating with Cloudflare, Meta, and the Freedom of the Press Foundation to standardize the approach. Test the prototype at waict.dev, including an E2EE video calling demo.
