Sharing bookmarks between Firefox in Ubuntu and Firefox in OSX
Assuming you are dual booting OSX and Ubuntu, with read/write access from Ubuntu in to your OSX partition, here is a method to share the same bookmarks.
In Firefox 3, bookmarks are stored in your profile folder, in a file called spaces.sqlite. We are going to delete the spaces.sqlite in your Ubuntu Firefox profile and create a symlink to the same file in your OSX partition.
Make sure to close Firefox and backup your spaces.sqlite files first.
The command should be something like this:
ln -s /media/mac/Users/john/Library/Application\ Support/Firefox/Profiles/uuuvglig.default/spaces.sqlite
/home/john/.mozilla/firefox/cqzxegul.default/spaces.sqlite
in other words:
ln -s /path/to/real/file /path/to/non-existent/file
This will create a soft symbolic link in your Ubuntu Firefox profile folder.
