Red button on the top left closes apps?

[mycol23]

Since I installed MacOs Sierra, my apps closes when I click to the red button on the to left of the window, for example, when I am click on the red button of a safari Window it closes the app and a lose all of my tabs. Also when using iTunes and playing music, I click on the red button and the music still playing but it iTunes disappears from mission control. The white dot on the base of the icon remains. Is anybody experiencing this?

It sounds to me like it's working as it always has (and as it's designed to)?

Yep. Closing the window will close the tabs in Safari. To keep the tabs, you have to quit Safari instead (Dock → ‘Quit’). You can restore the window and its tabs from the ‘History’ menu as well.

Closing a window will also hide it from Mission Control. Mission Control only shows open, visible windows.

No, that button should not close the app, the app closes using cmd+q but now in my mac The botton closes the entire app.

Which apps?

Which apps?

All the apps.

So in other words, all apps lose the white dot below the Dock icon as soon as you close their windows? This is what Safari does?

Many if not most apps on OS X are single-window apps. They quit automatically. This is intentional.

The button closes the active window (and all its associated tabs), so pressing it on Safari will close all the tabs in the window you're closing, but won't close Safari down completely.
If the app has a single window, it may close the app completely or may leave it running in the background: iTunes stays running, but photos doesn't for example

Again, this is all exactly the same as previous OS X versions
