Item	Type	Severity	Description
browserSettings	Permission	High	This permission (Firefox) allows the extension to read and modify global browser settings, including proxy-adjacent networking, DNS-over-HTTPS and homepage configuration. Rated High because it can weaken browser security posture globally.
Contextual Risk Factors	Risk Factor	High	The following context increases the overall risk:• 15% increase: Older manifest version lacks modern security controls
management	Permission	Medium	This permission manages other installed extensions. Rated Medium because it can enable/disable other extensions and modify their settings, with changes being visible to users.
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.
Older Manifest Version	Risk Factor	Medium	This extension uses Manifest Version 2
alarms	Permission	Low	This permission schedules periodic tasks. Rated Low because it can only trigger events at specified times without access to sensitive data.
theme	Permission	Low	This permission (Firefox) changes the browser theme. Rated Low because it only affects visual appearance.

It's currently not being updated and still with bugs for something that should be simple. the github page has more than 30 issues open for many months now.

Automation based on the system theme doesn't work (FF 149 Windows). I don't understand how this can be "recommended"

Firefox 149 on macOS Tahoe 26.4 - Doesn't work - Tried automatic settings, tried set to system settings, tried manual setting...all the same...nice idea but 👎🏻
