The new “Footprint chooser” window is the new standard dialog for selecting footprints. The old window is currently available from the pcb editor–>View–>Footprint library browser. There is no flag/setting to change the displayed footprint selection dialog.
The missing ability to quickly measure something in the “footprint chooser” dialog is tracked in gitlab issue #17107: Measurement tool missing from footprint chooser (#17107) · Issues · KiCad / KiCad Source Code / kicad · GitLab
Note that the new “footprint chooser” dialog on the other hand offers some new improvements/additions, which may help in the everyday work.
