- Start the Profile manager
- Firefox.exe -P
- about:profiles (but less configuration available when opening in browser)
- Open external links in profile that is active. If no profile is active, open the profile manager
- Edit the profiles.ini (find in Users/%User%/AppDate/Roaming/Mozilla/Firefox)
- 1) The parameter
-no-remote
should be actually in your default profile target, so add the-no-remote
to the target of the shortcut you’re actually using to launch your default Firefox. Remove the-no-remote
parameter from the non default profile. - Check your
profiles.ini
file as mentioned above. It should contain following lines at the very beginning of the file:[General] StartWithLastProfile=0 [Profile0] ... file continues...
If it does not contain the first two lines, backup the profiles.ini and add the lines. Or change the
StartWithLastProfile
value from1
to0
.
