I need help with my extension (github.com)

so I was making an extension for firefox where it calculates and displays a user's Karma. Now the extension works perfectly fine when you paste in your profile and go there, or if you refresh your profile. but if you go to the main menu of Lemmy, then back to your profile by clicking on your profile, the extension simply doesn't work.

I ended up going primitive and used intervals to check if a particular div was visible: function refreshExtension() { console.log("checking ", shown); const targetNode = document.getElementsByClassName("person-details")[0]; if (!shown && targetNode) { main(); } if (!targetNode) { shown = false; } } setInterval(refreshExtension, 200);

will it affect performance?
