Reviews of Multiple Tab Handler

Multiple Tab Handler is valued for bringing necessary multi-tab selection and management features to Firefox, fulfilling a gap in the browser's native capabilities. Users appreciate its basic functionality but report recent stability issues like tabs deselecting unexpectedly and inability to copy selected tabs, which undermines its usefulness. Feature requests include improved customization such as color scheme changes and middle-click tab closing. Some users also note a lack of new export options and occasional lag in selection visuals.
