Why is the site I'm developing making third-party requests?

Question

JavaScript

In general, it starts the dev server, open the site in the browser and open the devtools console and see requests blocked by AdBlock:

In the Network tab, I found more strange things:
The question is, what kind of ad blocking is on the site, which is still being developed and lives on the dev server?
There are suspicions of frameworks and libs. Here is the list:

"dependencies": {
    "jquery": "^3.2.1",
    "fine-uploader": "^5.13.0",
    "switchery": "^0.8.2"
  }

Tell me what's the matter.

Answer 1

Maybe it's some kind of chrome plugin? On the right, it should say what initiated the request. Disable suspicious plugins (or open incognito mode) and check again.

Answer 2

If you hover your mouse over the entry in the initiator column on the network tab, then it will show where the request came from - from which script and line.
Values ​​like VM2399 are, in my opinion, most often browser extensions that add code to the page.
My IMHO - in some left extension and business.
Try a different browser or profile without extensions.

Answer 3

And if you disable AdBlock, then he does not swear?
In the same place in an error it is accurately written: it is blocked on the client. So something from the browser makes get requests somewhere.
Disable the ed block and everything should work.
Here is the actual answer))
