Try to use the full path to the Firefox program.

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

Still nothing happens. If I go to that site on my hard disc and click on firefox.exe it opens firefox.

This is the standard installation for Firefox - "C:\Program Files\Mozilla Firefox\firefox.exe" - is that where it is installed on your PC?

The Profile Manager won't open if Firefox is running or if there is a "hung" firefox.exe process in the Task Manager.

Yes. That is where it is installed.

If I type that address in the search box, the search replies that it can not be found. If I add "profilemanager", still can not be found.

When I did it this time I made sure firefox was turned off.

It seems like "profilemanager" should be a file in firefox and should be found like any other file. Obviously not.

Would really appreciate your help.

It's not a "file" it's an internal process.

Did you try using -P as suggested by cor-el, instead of profilemanager?

Still doesn't work.

You did place quotes around the full path to the Firefox program?

Surrounding quotes are required if a path has space characters like "Program Files" and "Mozilla Firefox" have.

Thanks for your help. I was not following instructions exactly, io.e. I goofed. I am in business now thanks to your help.

Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system.

i read the above direction however i do not even have the firefox.exe file they recommend? isn't there a way to just install MOZILLA FIREFOX from step 1 on the website?

please help i hate internet explorer

For that question open a new thread like you did at https://support.mozilla.com/en-US/questions/809278

First close firefox. Enter at the command prompt "firefox --profilemanager" (without the quotes) and it should work

Why dig up a solved 4 month old question and then post inaccurate information?

The double hyphen won't work!
