Welcome to our community! :smiley:

Can you check firefox's console in developer tools and see if there is anything relevant?

It shows the error liks this:
Content Security Policy: The page’s settings blocked the loading of a resource at inline (“script-src”). home:342:1
^ A single error about an inline script not firing due to content security policy is expected! bootstrap.js:43:20
window.controllers/Controllers is deprecated. Do not use it for UA detection. kbn-ui-shared-deps.js:380:984495
This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”.
