Share firefox profile across multiple operating systems.


I've recently installed windows 8 on a VHD (my main OS is Windows 7) and I was wondering if it was possible to share the same firefox profile on both operating systems. I have the profile manager from ftp://ftp.mozilla.org/pub/mozilla.org/utilities/profilemanager/, but when I tried to make a new profile at the location of my main profile, it instead made a subdirectory under my main profile. Is there anything I can do to share the profile between the two? I could always use sync, but I would like to share my addons, if possible.

  • Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.
