Eclipse is always on top

My problem is that Eclipse is always on top. When I open Eclipse and I want to open other programs like for example Firefox by clicking their shortcut on the taskbar, the window opens up behind Eclipse.

Which eclipse is best for Java?

Eclipse 4.23 (2022-03) A Java 11 or newer JRE/JDK is required, LTS release are preferred to run all Eclipse 2022-03 packages based on Eclipse 4.23, with certain packages choosing to provide one by default. The Installer now also includes a JRE--consider using the Installer. Please see 5 Steps to Install Eclipse.

I'm using windows 7 and just encountered this problem. I found the solution is to press 'Ctrl + Alt + Esc'.
