Show Profile is a Firefox extension designed for users who manage multiple profiles within the browser. This tool simplifies the identification of active profiles by adding a customizable prefix to the window title, making it easier to distinguish between them at a glance. Users can set this prefix in the options menu, with the default being 'DEFAULT'. The extension also offers flexibility in displaying hints in various locations on the browser, such as the window title, menu bar, or status bar, without altering tab titles.

In addition to the title customization, Show Profile allows users to open the corresponding profile folder directly. The extension supports personalized settings, including a user-defined 16x16 pixel image for icons. Users can choose to display hints temporarily or set them permanently, enhancing the overall organization and usability of multiple profiles. This tool is particularly beneficial for users who frequently switch between different profiles for personal and professional browsing.
