example-chrome-extension VS adblock-rust

Shameless plug: I was totally dissatisfied with the state of extension documentation and tutorials, so I wrote a book on building Chrome extensions: https://www.buildingbrowserextensions.com/

I was enthusiastic enough about extensions that I decided to publish a book about building them: https://www.buildingbrowserextensions.com/

Browser extensions are severely underrated as a platform because they aren't sexy. For all that mobile devices have given us, so much of our work continues to be done using a desktop browser. Enhancements such as augmenting websites with widgets, supplying contextual information, and automating repetitive tasks using the authenticated session - when applied appropriately - can save someone hours every day.

Browser extensions. Not quite a website, not quite a mobile app, and surprisingly pervasive. Most people don't realize how incredibly powerful they are, even with manifest v3.

I almost fell out of my chair when I found out there were no books on how to build them, so I wrote one: https://www.buildingbrowserextensions.com/ It was incredibly enjoyable to go through the APIs and write about all the different crazy things they can do.

I was frustrated with the lack of resources, so I'm publishing a book on it: "Building Browser Extensions". Available later this year. https://www.buildingbrowserextensions.com/

And check out the companion extension: https://www.buildingbrowserextensions.com/b2x

Brave has written their own (open source) adblock engine (in rust) that is directly integrated into the browser (ie. not an extension, so is not affected by Manifest V3).

Here is a (somewhat dated) article describing it by the authors:

https://brave.com/improved-ad-blocker-performance/

Brave has its own Rust implementation of an adblocker embedded in the browser: https://github.com/brave/adblock-rust; so it does not embed uBlock Origin (but the filters are mostly compatible)

Disclaimer: I work at Brave but not on the browser.

We support :has currently, which impacts many filters in EL and uBO. Some non-supported filters such as upward() can be manually converted over to use :has instead. The other unsupported procedual filters are a WIP will depend how easy/hard they are implement. No ETA, but have opened a ticket https://github.com/brave/adblock-rust/issues/293

ublock on chromium and brave itself can't use all of the filters in that list: https://github.com/brave/adblock-rust/issues/4

It's open source https://github.com/brave/adblock-rust

I've fixed this in the adblock engine as of https://github.com/brave/adblock-rust/commit/8a755bdb190bb55a3a3acee1e6507085051bdeec, and I'll push to get this patched in 1.47 soon. Thanks for the reports!
