I did what you did in first screen (typed firefox -p in run window) but i don't see the option to choose user profile like you do in second screen. It just took me directly to open a new firefox window. Do you know why?
You can launch firefox profile in different ways. Try the below methods before that i recommend you to close all firefox instances before try the below methods. Check the Task Manager if there is any firefox instance running. If it is running then please close it and try the below commands in run mode(Windows Key + R).
firefox.exe -p
firefox.exe -P
firefox.exe -ProfileManager
If the above methods doesn't work then you have to copy the full path where you have installed your Mozilla Firefox.
If your machine is a 32bit then it will be installed in Program files which means you have to run the command with full path like below:
C:\Program Files\Mozilla Firefox\firefox.exe -P
If your machine is a 64bit then it will be installed in Program Files (x86) which means you have to run the command with full path:
C:\Program Files (x86)\Mozilla Firefox\firefox.exe -P
Try the above methods and let me know if you are able to launch firefox profile manager.
IMPORTANT: Please close all firefox instances including from task manager before you try the above methods.
