webRequest is still around for now, but Manifest v2 as a whole will be deprecated sooner or later and I think webRequest goes away with it. I don't know if Google has specified dates for this, but for historical context here's the timeline from Manifest v1: https://developer.chrome.com/extensions/manifestVersion#manifest-v1-support-schedule https://developer.chrome.com/extensions/manifestVersion#mani... Deprecated in March 2012, stopped accepting updates to Manifest v1 extensions in March 2013, and existing extensions stopped working in January 2014. EDIT: Google's blog post talks a lot about removing the "blocking version of webRequest", so perhaps the monitoring one still exists? But their goal would be to make these into separate permissions - the very popular blocking extensions can work blindly, while monitoring extensions can still function? It's not very explicit about it, but that's how I'm reading it https://blog.chromium.org/2018/10/trustworthy-chrome-extensions-by-default.html https://blog.chromium.org/2018/10/trustworthy-chrome-extensi...
