If you can afford it, I'd suggest switching to AdNauseam ( https://adnauseam.io ). They're using the same uBlock Origin engine, but ads are downloaded and clicked on in the background. This way you still generate revenue for site owners. But since this extension is banned from the Chrome Web Store, you'll have to install it manually there. On Firefox it's available from their add-on store.

This is based on a misunderstanding of how ads work and does harm. If this silently clicks ads in the background the click rate goes up but the goal action (buying, signing up) remains at 0 which smartprices the ads and tanks the value of the ads for the real clickthroughs. If you must block ads just use uBlock Origin so you are treated like your visit doesn't exist. A deeper question is it moral to consume content a…

jQuery is a large library, but it isn't exactly the source of web performance issues in my experience. It's the way it's used: many sites use it to render content, especially above-the-fold content (like image galleries, such as on ecommerce sites). Since much jQuery-based code waits for the DOM to finish loading first (e.g. with `$(function() { ... })`) [0], that means all the HTML has to finish being parsed and loa…

> That means the browser stops parsing the HTML mid-way through the page load, resolves the CDN's domain to IP, does a TLS handshake and establishes a connection to the CDN, waits to download the script, parses, runs it, and then proceeds on to the rest of the HTML. This is not true since about 2008. All major browsers parse the HTML without waiting for synchronous to load. https://developer.mozilla.org/en-US/docs/Gl…

uBlock is what's keeping me from switching to Safari (which is so much nicer to use on a Mac) It seems like most people who use Safari use full system-level ad blockers like Wipr. But I was also Googling around and found some complaints about Wipr, like it taking forever to be updated to block YouTube ads when they switch how they're displayed, or not being as good at getting around ad-block detection on certain site…

I've recently switched to macOS and Safari with Wipr. I don't see much difference to my Firefox setup with AdNauseam (uBlock Origin) before. More on the contrary - my selected lists were very aggressive and I had various sites where I had to disable uBlock to see them properly. With Safari and Wipr, everything seems to just work.

Use an adblocker. I save about 25 gigs and hours of my time every month. * https://www.ublockorigin.com * I block much more than ads.
