There seems to be an issue when trying to buy and/or download addon's.

When trying the downloading or clicking "Get this Item" button on Minecraft Marketplace it just takes you to a new tab that loads blankly almost forever. Counted 30mins of it being the only tab open and window running (no background apps or programs open to see if it would quicken the loading process for the tab) and no luck. No loaded tab and nothing new in downloads. This goes for Free items and items that cost Minecraft currency.

Cannot drag addon into Minecraft Resource backs from tab directly either when double checking different methods to get addon.

Can be signed in on official Minecraft website and nothing changes, and when trying download it does not prompt sign-in for purchase if not.

Down below I have a screenshot of Addon I tried and the tab it opened.

Is this an overall issue or just a Windows issue?
