uBlock Origin performance improvements thanks to WASM (Firefox only, for now)

[harlan4096]

The most recent version of the content blocking extension uBlock Origin uses WebAssembly (WASM) code to improve the performance of the extension.

The new uBlock Origin 1.17.4 is already available on the GitHub project website and Google and Mozilla web stores for extensions.

The new versions get pushed out to users in a rolled released which means that you may not get it immediately. Chrome and Firefox users may enforce the update. Chrome users may want to read how to update Chrome extensions manually for information on how that is done, Firefox users may check this guide instead.

Raymond Hill (gorhill) notes that the new code is only active in the Firefox extension and not in the extension for Google Chrome. The reason for that is that Google Chrome does not allow wasm "without adding 'unsafe-eval' to the extension's own Content Security Policy in its manifest" which Raymond considers unsafe for use).
