Straight Talk's live chat isn't supported in Firefox apparently

I went to their site in Chrome, and the button shows up now. Why support Chrome but not Firefox?

Doesn’t actually work. Inspecting the page, there’s an access denied error for the local storage.

Haha, tracking protection blocks the chat in Firefox. Inspect the page, go to console, and you’ll see.

There’s the chat in Linux in Firefox. Does the same in Chrome. Almost closed anyways.
