How to open Profile Manager in Firefox 57

Whenever I 'Run' firefox.exe -F with FF57 installed it just goes to a blank FF screen. I've also use -profilemanger in additon to -F.

Does FF57 require something different?

Thank you

firefox.exe -P

Thanks for the try but all it does is to open FF to a blank page like the others.

Do you have more than one profile and is Firefox open?

This is the shortcut I had pinned to my Start long before the update to 57 (in fact, It's been there since 2015) . It still works for 57.

"C:\Program Files\Mozilla Firefox\firefox.exe" -p

As Edwin points out, Firefox must be closed before you can run the Profile Manager.

Thanks to Edwin and Bree. I had forgotten that FF had to be closed to be able to use the profile manager.
