Disable WebUSB (delisted)

Description from extension meta

Disables the WebUSB API for all websites.

Description from store Disable WebUSB disables the WebUSB API for all websites. WebUSB provides access to devices that may not be designed with an adversarial threat model in mind, protected only by a permissions dialog that does not make the risks clear. Given the lack of widely-deployed uses of WebUSB, disabling it is a prudent defense-in-depth measure.

  • (2019-11-13) Ken Adams: im guessing its intentional that there are no settings because its such a simple extension? If so, I would suggest a post-installation explanation, super simple just explain that there are no configurable settings and not to worry it is working as designed.
