I'm a bit of a beginner in React and I'm wondering why by not using "WeakMap" anywhere I have a problem with it in Firefox browser, but if I run the same React application on Chrome or Firefox Developer Edition, it no longer throws me this error. Did I forget to click some checkbox, is Firefox not adapted, or do I have a lack of knowledge?
I would appreciate a clarification, because I like to know how something works, and Google and ChatGPT are not helping with this topic.
