Installation via Quickstart isn't working

Installed Python 3,10
Installed Instapy

-> When running the basic Quickstart it first opens in Firefox? Shouldn't this be Chrome by default?
Second, it is able to log in, but following after it directly goes to the link: https://www.instagram.com/'username' and then Firefox tells me it cannot find the page. Anybody know how to tackle?

The code is exactly the same as downloaded exept with my login credentials.

Start by reproducing the basic Quickstart with Python 3.10 and the downloaded code, using the reported login flow. Check why Firefox opens instead of Chrome and why navigation produces an invalid Instagram URL; done means the Quickstart opens the intended browser and reaches the correct destination after login.
