I cannot answer your question about the
third party browser extensions - I just don't know.
In some cases you will have to log off/on to get the un-/selected options in-/active.
Select the options that best fit your preferences.
Following I tried a short description of the options from my experience:
Folder Options X 1.6.0.0 HelpDisable full row selectEnables the main feature to reduce the line spacing in details view as it was with Windows XP.
Selects also the option "Enable icon reordering".
Disables the Windows 7 feature to select a complete line in details view as it was with Windows XP.
Remark:
In Windows 7 you can activate this feature but then you cannot unselect an object by clicking in white space in the explorer window details view. It always selects the object displayed in this line. You only can unselect by clicking in the white space on the left margin of the line. This white space disappears with this option of the tool activated.
Column headers in all viewsDisplays always the headers of the details view regardless of the view selected (e.g. symbols view).
Selects also the option "Enable icon reordering".
Enable icon reorderingIn symbols view you can reorder the symbols by click & drag as it was with Windows XP. In Windows 7 this feature is not available anymore. This option can be activated independently but it will be forced active when "Disable full row select" is activated.
Keep focus on file list viewWith this option active you can only select objects in the file list window of explorer. You still can click on objects in the navigation pane but they will not be selected. Nevertheless the clicked folder contents will display in the file list window.
