mak2, you can create a shortcut to the about:profiles page in the bookmarks toolbar. open about:profiles and bookmark it. Place the bookmark in the bookmarks toolbar for easy access. Or: Open the library with ctrl+shift+O and navigate to the bookmarks toolbar, then select Organise > Add Bookmark… You can enter "about:profiles" in the URL field. Either way, in the main window, as long as the bookmarks toolbar is visible (ctrl+shift+B) you will have a quick way to get to the profile switching page. Another method is to use command-line options to launch profiles. You can create shortcuts on the desktop or in the start menu that look like either of the following: "C:\Program Files\Mozilla Firefox\firefox.exe" -P "profile_name" "C:\Program Files\Mozilla Firefox\firefox.exe" -profile "profile_path" (where "C:\Program Files\Mozilla Firefox\firefox.exe" can be replaced if your Firefox was installed to a different folder) Unfortunately I personally do not know of any quicker way than these. But other people have also been requesting a simpler profile-switching method, see https://connect.mozilla.org/t5/ideas/shortcut-for-different-profiles/idi-p/707 According to this page this is 'in development'. If you wanted you could Add kudos to the original post as Firefox developers use this site to track interest in feature suggestions.
