Advice generator app

Keep in mind, I just learned about fetch() and getting data from outside sources. The problem I have though is that the json data doesn't change after hitting the advice button in mozilla. I got it to work in other browsers and on my phone/tablet, but mozilla is giving me an error. It does work and changes content if the use deletes their cache, but problem continues where if the user wants more randomized advice, then they would need to delete the cache each time before hitting the button.

Besides that issue, please help me with any suggestions or feedback! Thanks!
