so that is disable links launching Windows Store on Windows 8/8.1/10

Do you really want a link for ilovetaylorswift.com opening up somewhere else other than your default browser?

Edit: just kidding about the taylor swift thing

Try this link https://www.microsoft.com/store/apps/9nblggh2s4gt ... If you click on it in a browser on Windows 10, the games' page on the Microsoft Store websites gets opened, and so does the Windows Store application and the game's page there.

It's a privacy thing: I wouldn't want a Windows App (with a MS tracking ID, license, username, account, whatever?) getting info on all the windows store things I look at (which is zero, but that's besides the point)

If you click on it in a browser on Windows 10, the games' page on the Microsoft Store websites gets opened, and so does the Windows Store application and the game's page there.

It doesn't though.
Nothing will open until you click Get, at which point it's quite obvious you're wanting to open Microsoft Store and install the app.

Note that windows store is one of a very few handlers that have no warning dialogs

• see https://searchfox.org/mozilla-central/source/browser/app/profile/firefox.js#975-982

also FYI

• FF101+: 1756209 Support attribution from the Microsoft Store
• this is a nothing burger, a campaign id is not PII and no-one cares, especially me since we nix the handler anyway

So this was added in FF24: 866065

Which leads to bugzilla 1677753 Show permission prompt before opening macOS or windows app store via external protocol.

That bugzilla is confusing - it shows that there is a permission prompt, so IDFK

Anyway the pref stays as is

url: https://www.microsoft.com/en-nz/p/monster-go/9nblggh2s4gt?rtc=1&activetab=pivot:overviewtab
pref: network.protocol-handler.external.ms-windows-store
os: windows 11
test: click get

pref true (default) - opens MS store (I have no ms account, btw) - no prompting
pref false (AF) - nothing happens

If you're on windows, I guess you can just open edge IMO

then again, I agree, you wanted to install it .. so yup, let's remove that pref
