You posted with a Mac user agent.

Do you want to make the change on a Windows computer or the the Mac that you posted this with?

On a windows ,I always start firefox with other profile ,so I use "c:\firefox\firefox.exe --no-remote -profile "c:\firefox\user\"" to start my firefox,but,when I set my firefox as my default browser ,when I click a web link,firefox started without my profile dir like "c:\firefox\user\"

You will have to use the Profile Manager to select the default profile an tick the box or edit the profiles.ini file and move the Default=1 line under the correct profile heading.

The OP (thread owner) doesn't want to use a profiles.ini file, but prefers to start Firefox by specifying the absolute location of the profile via the target in the desktop shortcut (-profile "<path>").
In this case Firefox doesn't know which profile to use when you open a file with the default browser and Firefox isn't running yet.
A possibility would be to edit all involved registry keys (e.g. HKEY_CLASSES_ROOT\.html) and add this switch, but that may not last and is difficult to maintain.
