When using the Firefox browser in Ubuntu, you will not have your existing bookmarks and other data such as stored passwords from Firefox in Windows. However, it's easy to copy these over:
You will find your original bookmarks by opening up Filesystem in Linux and selecting Host, then going into Documents and Settings > Application Data > Mozilla > Firefox> Profiles. Here you should find a folder ending in “.default.”
(If you have more than one user account in Windows, your user name will appear in this route between “Documents and Settings” and “Application Data.”)
Now open the Home folder in a separate windows and, if necessary, press CTRL+H to show hidden folders. To locate the bookmarks for your Ubuntu version of Firefox, open the Mozilla folder, and then open the Firefox folder. This should bring up another folder ending “.default” but with a different name.
The final task is to replace this folder with the folder you opened in Windows, but keeping the same name. The safest way to do this is:
- rename the folder in Ubuntu by adding 'old' to the start of the name.
- copy across the folder from Windows into Ubuntu
- rename this folder to the name of the original Ubuntu folder
Next time you open Ubuntu, you should find all your old bookmarks and other data are working. The only downside is that when you next add a bookmark using Firefox in Ubuntu, it won't show up when using Firefox in Windows and vice versa.
