Ok weil I feel better now that it's not just me. However I'm still not completely relieved.
When I use the Chrome browser the files download like normal, as far.
With Firefox that I normally use and have uses for a long time, they are zip. Here's where it gets even more strange. I renamed \Roaming\Mozilla\ folder. Opened Firefox so it created a new fresh Mozilla folder and tried the exact same download and it downloaded fine. So I thought it might be an add-on. So I switched back to my normal Mozilla folder, tried it again still doing zip as "expected." (always good to test the expected bug first again just in case) Tried opening a Private browser and it still did it. I tried to manually remove all of the add-ons, even though I know that Private does that well, and still got a zip.
