Describe the bug

The Firefox for Android User-Agent shouldn't include a device model, but this extension incorrectly includes the device model. This is a very obvious fingerprint.

Why shouldn't it? I have found some examples:

• https://explore.whatismybrowser.com/useragents/parse/662081-firefox-android-gecko
• https://explore.whatismybrowser.com/useragents/parse/662194-firefox-android-gecko
• https://explore.whatismybrowser.com/useragents/parse/662197-firefox-android-gecko

In these cases, the device model is included

The data on the website you mentioned is inaccurate, you can download Firefox for Android and see for yourself, there is no model information at all, and there is no ESR version on Android. And there is no "Android 9.3".
