why fine checking tool not working

Firefox Web compatibility

Hi,

I’m facing an issue with my website’s fine checking tool on Mozilla Firefox. My website is evgfinescheck.com , and the tool works fine in some browsers, but on Firefox it doesn’t load properly and sometimes shows an error.

I am already using the latest (updated) version of Firefox, so the issue is not due to an outdated browser. The tool either fails to fetch data or doesn’t respond as expected when users try to check fines.

I’ve checked basic things like internet connection and browser updates, but the problem still persists specifically on Firefox.

Can anyone guide me on:

What could be causing this compatibility issue? Are there any common JavaScript, API, or CORS-related problems specific to Firefox? How can I debug or fix this issue?

Any help would be appreciated. Thanks!

Hi

What is the error you are seeing when you try to use this site in Firefox?

I’m experiencing a very similar issue, although in my case it’s related to a CURP download tool. Everything seems to work correctly in some browsers, but on Firefox the tool occasionally fails to load data or complete the request.

I’ve already checked browser updates, cache, and basic settings, but the problem still persists. I’m wondering if Firefox is handling certain JavaScript functions, API requests, or CORS policies differently.

For reference, the issue occurs on https://descargar-curp.com.mx/ as well. If anyone has found a reliable way to debug or fix browser-specific compatibility problems, I’d appreciate your advice.

Well, Jimmy, and what exact browser version that is? (Since the question was submitted from Chrome…)

(Do you realize you're commenting on your own post? Maybe you forgot to switch accounts before "chiming in". Also, links here are nofollow, so there's no reason to be adding more AI–generated posts with mysterious issues, such "SEO" efforts have no effect here so you should focus elsewhere perhaps.)

If you're the author of the site as you claim in one post, what JS APIs and CORS setup you use that would be differing? If you're "experiencing a very similar issue, although in my case" that's not authored by you, report the issues to the site operators.
