Though I don't see how another browser would change things.
Potentially, it could change EVERYTHING for you. Browsers have a huge mass of different settings & features that can affect things like this. Any time that yopu have any difficulties on any website, and you've checked all the obvious stuff, the next step is to try it with a different browser. Often the other browser will work where the current one didn't, and when it doesn't work either, that still helps you narrow down the problem because you can then safely eliminate all the browser-related issues & know that the problem lies elsewhere.
