How to disable certain scripts on the site?

Question

JavaScript

Hello. Is there an add-on "User javascript and css" with which you can add a script, but is it possible to disable certain scripts on the site? I just wanted to replace the script with my own, but first I need to disable the script from the site

Answer 1

The script can be blocked with an ad blocker. (you don't use blockers? are you crazy?)
In most cases, you don't need to block anything, just change the necessary parts at the js level:
1. run the script on document-start;
2. hang up a getter on a global variable (if any) or replace standard things (eg XMLHttpRequest).

Answer 2

Use the noscript extension.
Well, or use https://www.telerik.com/fiddler
There you can do a lot of things to replace scripts, cookies, tokens, forms and other things
