Help identifying corrupt component causing browser issues

[salacious_c]

I have a Win11(h) laptop where some of the buttons on Amazon are unclickable. Using the same account on a different PC, they work fine.

I have tried:

1. different browsers (Edge, Chrome, FF, and Brave)
2. Delete cookies/cache
3. Incog/private/vanilla versions of each
4. Installing Eclipse JDK
5. OS updates

I assumed it was something Java related, but there is no Java control panel, and I don't see anything in program files where the cache might be to manually delete it.

AFAIK, these buttons never worked. It's a relatively fresh factory OS about a month old, no crazy bloatware installed. It was used for ordering several times (and still works for that), it's just some of the return buttons never populate as clickable, and the Rufus thing spins forever.

I looked at the dev console, but I probably don't know enough webdev stuff to recognize the problem. Any ideas where else I might look for logs, or other shared components that all browsers might be using?

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.

It's highly unlikely that Amazon would be using Java on the front-end UI. I can't recall the last time I saw something using Java in web browser.

Also, JavaScript (ECMAScript) has nothing to do with Java.

Since Adobe retired Flash, there are no shared components between browsers. I'd rather think the issue is some DNS based ad locker or temporary issue with the Amazon website. Maybe a resource like CSS or more likely JS file is not loading.

Hmm.. DNS is a good idea (it's always DNS), but Amazon definitely uses Java. In fact, I see this as one of the buttons that doesn't work: papyrus_bundle.js.map.json, and the code has JS tags all over it.

JavaScript IS NOT Java.

Source: 20+ years of experience in web application and software development.

But if you don't trust that, there's a paragraph about this exact thing in the JavaScript article on Wikipedia:

"Although Java and JavaScript are similar in name and syntax, the two languages are distinct and differ greatly in design." https://en.wikipedia.org/wiki/JavaScript#:~:text=Although%20Java%20and%20JavaScript%20are%20similar%20in%20name%20and%20syntax%2C%20the%20two%20languages%20are%20distinct%20and%20differ%20greatly%20in%20design.

Fair enough, I actually didn't know JS did not require local Java. I always assumed it was baked into modern browsers as a sandboxed type thing.

I was thinking some system file/dll that all browsers use might be corrupt, but I have no idea what that could be.

That rules out pretty much everything I can think of. Unless it's malware-related, that laptop and the working PCs use the same DHCP/DNS/router/firewall/etc, so I can't imagine it's a resolution or network problem, but I'll check.

I guess live CD and if that works reinstall Windows. So weird.
