Hi Alexander,

Yes use a second profile and the -no-remote argument in the none default browser comandline or shortcut. Post back with how you get in or for more information

Cheers John,

Using multiple profiles is not something we shout about on this forum. It is I think considered too advanced. It does have some dangers in that you may accidentally delete profiles for instance. It is however possible to manually backup profiles, and that may be a good precaution to take. I would also strongly suggest that you follow this good practice (At least until you are proficient enough to manually recreate and modify profiles)

1. Normally use the locations suggested by Firefox
   It is easier and safer
   • Always use an empty folder
     Other contents disappear when the profile is removed
   • Never nest profiles within each other
     As above,delete mother, lose child also
2. Do not rename profiles
   Confusing, profile names and folder names mismatch
3. Do not delete profiles
   Just remove shortcuts if not in use. Delete the wrong one and you lose settings, passwords & bookmarks etc

Uses of multiple profiles include

• Testing, with clean or temporary profiles
• Different users, or different work type within the same OS account. That may include different bookmarks files &/or a different set of addons.
• Running multiple Firefox versions &/or multiple instances of Firefox simultaneously.

There are other methods of creating profiles but the best is probably to use Firefox's built-in profile manager.

Indeed, without your response to me it was hard to get to the startup options for Firefox.exe with another profile. And documentation in the links on this theme is quite understandable. I'm trying to work with the two profiles in parallel during one week. So far everything has worked quickly and flawlessly. Although, after creating second profile I had to copy bookmarks from the first profile in the second profile with method of backup/restore. And then it turned out that the "Add-Ons" also need to copy from subdirectories profile "default" in subdirectories of the second profile. But now everything is working perfectly.

The essence of my question was in speeding up my work with the Internet, but the reason for the low speed was not in Firefox. Low speed was slow work of the print job with driver "PDF Creator". When sending a print of a long and complex HTML page from the Firefox in a PDF file, It takes for a whole minute, wait a parcel on the print. Under the words "wait a parcel" I understand "to sit and useless to spend one minute in idleness". Before the function, parallel browser for me was Opera-12.X, but lately project Opera became stupid, like "Google Chrome browser", so I had to find a way with the second profile Firefox. This method has worked well, so thank you, John.

Glad to have helped. Good to know you are finding this useful in running an additional Firefox profile.

It is actually possible to sync bookmarks between Firefox profiles using Firefox sync, but if you are just using a 2nd or even a 3rd process merely to save time whilst running print jobs on a secondary profile there is probably no need to customise those secondary profiles.
