Network indicators

24 URLs and 1 IP literals were extracted from this version.

Item	Type	Severity	Description
scripting	Permission	Critical	This permission allows injection and execution of JavaScript on any webpage. Rated Critical because it can modify page content, steal sensitive data, and inject malicious code into any site the extension has access to.
activeTab	Permission	Medium	This permission grants temporary access to the current tab. Rated Medium because it can access current page content when invoked, though limited to user-initiated actions.
storage	Permission	Medium	This permission allows storing data locally in the browser. Rated Medium because it can persist sensitive user data, track user activities over time, and potentially store malicious payloads.

Negative

Does not remember your choice, so every time you come back to a page or navigate to a different page on the same site you have to increase it all over again. Maybe this is acceptable on desktop but it's borderline useless on mobile Firefox where pressing the button requires four taps and scrolling through the list of extensions to get to it. Edit: I'm not "using the review page as a support forum", I'm reviewing the extension by pointing out a feature it does not have but which people probably expect it to.

Is said to be compatible with Firefox android, but actually doesn't work there.
