I wouldn't have been bothered by this at all (including the splash), if Windows hadn't reassigned Edge as my default PDF handler. Delving into the dark guts of the default programs settings, and finding a way to convince Windows that it was alright for Firefox to open PDFs even though it hadn't been installed from the Windows Store, took a far longer context switch than it deserved.

Right click a file (a PDF in ur case), click properties. Click "change". Choose the default file handler for that file type.
