If you regularly use different browsers, it’s most likely that they occupy most of the space in your taskbar. But it can be otherwise:
The software that organizes all of this is called Browser Chooser . It determines the browsers installed in the system and allows you to add up to 5 items to the list from among certain ones or along an arbitrary path. There is a convenient jumplist on the icon in the taskbar and a separate menu in the style of Aero. ')
PS Win XP is supported (naturally, without the jumplist)
