Unexpected behavior when testing third-party tools in web projects

Hi all,

I’m running into an issue where a small third-party tool works fine locally, but starts behaving inconsistently once integrated into a web project and tested in the browser. I’m not sure if this is related to sandboxing, permission handling, or recent browser security changes.

While troubleshooting, I checked an example via open link and noticed similar behavior patterns, which made me wonder if this is more of a browser or environment-related limitation rather than a code issue.

Has anyone faced something similar, especially when moving from local testing to a live or semi-live environment? What’s usually the first thing you verify in these cases?
