Makes it easier to read Content-Security-Policy (CSP) and Feature-Policy (FP) headers, and checks that all other related headers have been set for the HTML and linked resources (e.g. Referrer-Policy).
It can also set a "X-Dev-Key" header on all requests to your server, where the value is typically kept as a secret, and allows your server to enable additional debug information (just as an extra precaution, your server should also check the source IP address, and ideally that you are logged in).
Extore is a team of professionals who are passionate about creating extensions for web browsers. This devotion also gives us opportunity to appreciate work of other people. We get inspired by useful, open source extensions made by developers all over the world. Our strong belief is that one should share helpful add-ons with others. That’s why we’d like to present you our ever-growing list of favourite extensions that have inspired us. Moreover, as you probably have already learned, sometimes struggling for the best brings an end to the good. Talking about add-ons it often turns out that an upgrade is worse then previous version. Also it can become really tricky to get back to the beloved version of your favourite extension. That’s why we’re going to make not only the latest, but all versions of our favourite (and we hope yours too) add-ons available for download. No more compromises, just stick to the version you really like!
