"Search text selection in new tab" have a option "focus new tab - on/off". And this command only work with focus new tab is OFF. So, only works in background tab. Firefox disable foreground search activities for this addon.
Because of that, we need same "focus new tab - on/off" option for the "[Popup] Search engines" command. Obviously from the same reason.

gestures settings not responding mouse or keyboard to edit command on a new or existing gesture

Great extension, offering extensive configuration options. However, it has several limitations when used with Firefox, such as issues with new tabs, the tab bar, Mozilla's website, and other web pages. In comparison, Vivaldi integrates this type of gesture functionality directly into the browser, making it more seamless. While Gesturefy's restrictions may stem from Firefox itself, these limitations impact usability daily.
