Key notes
If you are a programmer and have been coding for some time, you must have encountered a situation where an event listener is not working in your Firefox browser. Event listeners, like all other APIs, are not cross-browser compatible and may present some problems.
An event listener is a function that is called when an event occurs. It can be associated with an element in the DOM, such as a button or a link. It is why you need abrowser dedicated for web developmentfor the best outcome.
When an event listener is created, it is attached to the DOM element with a specific ID. So if you have multiple elements on your page with the same ID, only one listener will be called when the element receives an event.
While you expect things to run smoothly, sometimes your browser may present problems, and your event listener may not be firing up as it should.
Why are my event listeners not working?
If your event listeners are not working, here are some possible reasons why:
How do I know if an event listener is working?
You can use the Firefox Dev Tools to inspect the DOM and check for the presence of your custom attributes.
If your code is wrong, then the event listener won’t work. But if your code is right, then there’s no way to tell whether an event listener will work until after it’s been used in a real-world situation with real-world requirements.
Quick Tip:
Another solid browser that supports event listeners is Opera One. The browser can schedule events in the document queues more effectively with passive event listeners.
This is particularly handy in touch and wheel interactions, as it prevents the browser from generating redundant scroll events. Furthermore, Opera One comes with build-ins such as VPN, Ad blocker and AI.

What can I do if event listeners are not working in Firefox?
1. Update your browser
2. Check your code
The first thing to check is the syntax of your code. Make sure that you have written it correctly and that you have included all of the required code.
It is possible that the event listener was not attached to the right element. For example, if you’re listening for clicks on buttons, ensure that your code is actually attached to a button.
3. Enable JavaScript
If you have tried all the solutions, but your event listener is still not working in Firefox, try using a different browser. If the event works in one browser but not another, it might be a problem with how the browser handles events or how it renders your page.
You can also try usingcode writing softwareto help you get the job done easily and minimize any mistakes.
