Congratulations to the author, and thank you for this add-on!
I am using WebApiManager along with UMatrix... what a nice complement! With this two adds-on is hard to need other ad-blockers, anti-tracking, cookie managers etc. It might be great a kind of fusion of this two great adds-on. First, due to potential gains in performance (less system resources, faster blocking etc). And second, because it will be easier to use WebApiManager in a matrix layout (like UMatrix). It would be perfect to have a matrix showing just active APIs for each webpage, allowing granular control for blocking/unblocking active APIs per webpage.
For now, please I just request from the author, to add in the dashboard an "enable/disable switch", or a kind of "temporary rules switch". And from us users community, it will be nice in the future to see a shared collection of customized settings of blocked APIs, for the most important websites (avoiding breaking pages and its functions).
Thanks again to the author!
PS: I read the articles attached by the author, found them very interesting, and recommend the reading in order to better understand the benefits (privacy, security, performance etc) of this great add-on. Quoting: "We evaluated our extension with two hardened browser configurations, and found that blocking 15 of the 74 standards avoids 52.0% of code paths related to previous CVEs, and 50.0% of implementation code identified by our metric, without affecting the functionality of 94.7% of measured websites."
