Firefox CCK Bookmarks being applied to already existing profiles

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Firefox CCK.
2. Launch Firefox for first time to create profile with defined bookmarks.
3. Install new Firefox CCK with added or changed bookmarks.
4) Re-launch Firefox. The bookmarks from the new CCK are added to an existing 
profile.

What is the expected output? What do you see instead?

Bookmarks from the newer CCK are added to the existing Firefox profile. In past 
versions of the CCK, only new profiles would receive the updated CCK.

What version of the product are you using? On what operating system?

Using cckwizard-1.3.5b6.xpi with Firefox 10.0.7 ESR on Mac OS X 10.5-10.8.

Please provide any additional information below.

This is undesirable for us because we frequently change the CCK and the 
bookmarks that computers receive. and will create issues with duplication.

Are you changing the version of your CCK when you make updates?

The CCK has always added bookmarks to new and existing profiles.

To prevent duplication, you change the CCK version and it will delete the old 
bookmarks and add the new ones.

Yes, I have been changing the version of the CCK. But, perhaps I have been 
doing something wrong. 

Is there anyway to not have the CCK apply to existing profiles?
