How to Identify Script Conflicts

Purpose

Explain common causes of script conflicts and how to identify them.

What a script conflict looks like

Common symptoms:

A tool loads on some pages but not others
A widget appears but does not respond
A tool works until another tool loads
Console errors appear during page load

Common causes

Global variables and namespace collisions

Two scripts may define the same global variable or override the same browser API.

Timing dependencies

Some tools assume another script has already loaded. If load order changes, the dependent tool can fail.

DOM manipulation races

Multiple scripts modifying the same elements can create unstable UI behavior.

CSP and blocked requests

Content Security Policy rules can block vendor scripts.

Public reference:

MDN: Content Security Policy (CSP) https://developer.mozilla.org/en-US/docs/Web/HTTP/CSP

How to identify conflicts

Use the browser console for errors.
Use the Network tab to confirm which scripts load.
Disable one tool at a time when possible to see if behavior changes.
