yeah no this is an evil script why would you do this

don't forget to put "https://cdn.jsdelivr.net/npm/devtools-detector" into ABP's blocked pages to disable this!

@catdotjs
Did you find any way to fool these damn devtoon detectors? I have a problem with puppeteer on a website

I'm also facing this problem, but in my case it's this link https://brbeast.com/video/f79921bbae40a577928b76d2fc3edc2a, if I search using uBlock the url https://cdn.jsdelivr.net/npm/devtools-detector, the video player starts playing the video and leaves the page, returning the navigation history to the previous page

@insinfo best thing to do is to really block non-essential packages. There is probably more than one dev detector or it is using a different dev detector.

Besides whats your goal with this? If you are trying to extract the m3u8 file. You can just install a network monitor program from apt or some other package manager.

Yes, I would like to extract the video, but it seems that there is no M3U8 file, from what I saw it is in a strange format, I still don't know how I can capture the video because the video is coming in chunks from this URL

  }

  Date.prototype.originalGetTime = Date.prototype.getTime;

  const originalOnMessageSetter = Object.getOwnPropertyDescriptor(Worker.prototype, 'onmessage').set;

@insinfo
You can do the following steps to avoid a devtool detector without breaking the page:

Open the DevTools
Go to Network panel and search for devtools-detector.js or something like this
Right-Click that file and click on "Block request URL"
Reload the page, you should get an error in the console that says:
Click on the link, this should take you to the Sources panel
Set a breakpoint at that error line
Reload the page, the debugger should stop at that line
Go to the Console panel and enter the following line this basically sets all functions to blank ones:
devtoolsDetector={addListener: ()=>{},launch:()=>{},versionMap:{}}
Go back to the Sources panel and resume the debugger

This successfully skips the devtools detector and does not break the page.
