Can you access your Windows partition from Ubuntu? Also, what version of Windows are you running?
If you can access your Windows partition, then you'll need to search for your profiles folder for Firefox. For me, on Windows 7 at work, my profile folder is located:
Code:
C:\Users\drmrgd\AppData\Roaming\Mozilla\Firefox\Profiles
On Windows XP it's similar, but I can't quite remember the path to a users application data. I think it's something like:
Code:
C:\Documents and Settings\<username>\Application Data\Mozilla\Firefox\Profiles\
Once you've found your profile folder, you can either copy the whole thing to your Ubuntu partition, or just get one of the bookmark backups and import that in. The advantage of the whole profile is that you'll also have your saved browsing history and settings and such.
Hope it helps!
