To install the developer build:

• Firefox: click this link and then click the uBlock0.firefox.signed.xpi link above
• Chromium: Install from the Chrome store: click this link

These developer builds will auto-update when a newer developer build become available.

Notes

I will keep bringing in WebAssembly ("wasm") versions of key portions of code where it is found to be beneficial.

In this release, a wasm version of the algorithm used to lookup a hostname from a set of hostnames has been created.

 

However, only the Firefox version of uBO benefits from this at this point, as it's is not possible to use wasm in

the Chromium version without adding 'unsafe-eval' to the extension's own Content Security Policy in its

manifest -- which is not something I am willing to do (my view is that any extension using 'unsafe-eval'

should be assumed malicious by default). It works in Firefox because the wasm module is loaded using a same-

origin fetch, meaning the module can only be loaded from uBO's own package, which is probably what

Chromium ought to implement.
