Safari ask for permission to open app, very annoying

While some Safari Extensions can trigger this new behavior, it is a new Safari-wide security feature that can be triggered by a variety of situations where Safari needs to open a macOS app via a custom URL.

We use Safari to automatically open FileMaker for our users from within notification emails, and this new feature has thrown a wrench into that legitimate purpose.

I posted feedback to Apple for the macOS Safari app asking that a "defaults write safari..." pref be created (if not a GUI pref) that allows us to revert to the older behavior for situations that require it. I urge others that have the same need to also submit feedback.

when you open apple map so you see just like this :

If you click on allow

As , I have not checked the box of maps app that's why it is showing maps is not authorised to access your location .

Apps that you have allowed to use Location Services appear in the Privacy pane of Security & Privacy preferences. Checkboxes show whether Location Services is turned on or off for an app. If you don’t want to allow Location Services for one or more apps, you can deselect (uncheck) the checkbox next to an app's name. If you turn Location Services off for an app, you are prompted for permission the next time that app requests to use your location data.

That does not help. I have the problem too: the particular app I am trying to open is Apple’s own Maps.app. It is one of the options if you use wikipedia and click on the coordinates on any page. For many things Apple’s maps is by far the best. But every time I see a dialog with the question ‘Do you want to allow this page to open “Maps”?’. This does not happen if I try to navigate to e.g. Google Maps, despite Google being far worse and less trustworthy over my privacy.

That’s not it: Maps.app has access to my location already, but it does not need it to work for what I use it for. Anyway, this is something that Safari does before it even launches Maps, so before Maps has a chance to check its permissions.

Open safari > its preferences > security > check the box of block pop up windows .

What is the application Safari is asking for?

Send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner.

Feedback

No Java here. I mean I have Java installed but Maps.app is not a Java app, the page that launches it, tools.wmflabs.org/geohack, is purely HTML.
