False positive when browser internal pdf is enabled

TLeiter opened this issue · comments

In Edge and Chrome if the setting "Open PDF in Chrome/Edge" is enabled (Settings > Privacy and security > Site settings > Additional content settings > PDF documents.), then the value navigator.plugins is empty which evalute the bot test to true.

Tested and not currently fixed.

Can you make sure you are on the latest version? Also please, send me botd snapshot from playgrond https://fingerprintjs.github.io/BotD/main/

Hello,

Hre is the snapshot from the playground:

@TLeiter I added support for detecting edge as BrowserKind, so it should fix the issue

We are encountering the same problem using the playground on latest Chrome, Chrome 119, Chrome 116. Steps are the same as the issue author described.

Would you look into it again?
