As a part of every page load, browsers have to make dozens, hundreds, or even thousands of decisions of varying levels of importance: should a particular API be available? Should a resource load be permitted? Should script be allowed to run? Should video be allowed to start playing automatically?

Previously, I’ve written a lot about Application Protocols, which are a simple and popular common mechanism for browsers to send a short string of data out to an external application for handling. For instance, mailto is a common example of a scheme treated as an Application Protocol; if you invoke mailto:someone@somewhere.com, the browser will convertContinue reading “Adding Protocol Schemes to Chromium”

Digital Signage (fullscreen) Requirements In the Digital Signage scenario, there’s a full-screen webpage rendering and there are no user-accessible input devices– the canonical example here wouldContinue reading “Lock down web browsing using Kiosk Mode”
Microsoft Edge’s Many Processes

For example, if a page on leaky.com has a memory leak that’s so bad that its tab crashes with an out-of-memory error, yourContinue reading “Microsoft Edge’s Many Processes”
