Protocol Handler Registration via Browser Extensions – make everything intensely
Custom URL schemes have traditionally served as an integration bridge between the browser and external capabilities. Schemes such as mailto: and tel: allow navigation to trigger actions beyond ordinary HTTP resource retrieval.
