Hi guys!
Firstly, huge thanks to TYPELiFE and MarkClouden for trying to help everyone out and providing help and assistance in trying to accomplish what should be a simple task, if only the Chrome developers had stopped to think that people might just want to export their bookmarks

):
1. Got hold of and installed Chromium build #4205 from link provided on Google Chrome Help
2. Copied bookmarks, history, cookies and preferences from Chrome user data to Chromium user data
3. Jumped up and down excitedly when I realised I'd got my bookmarks et al into Chromium
4. Stopped jumping up and down excitedly when I realised I still couldn't export them anywhere else easily
5. Eventually found MarkClouden's lovely little app and tried to get hold of my bookmarks from Chromium
6. Got an error message saying something about SQLite (didn't think to take note of it at the time, but I guess it was because I didn't have the SQLite Manager installed in Firefox)
7. Found this thread, and decided I probably needed to install SQLite, so installed SQLite and tried again. All appeared to work, but then opened up Firefox, and nothing had happened to the bookmarks
8. Consumed more coffee and cigarettes while plotting revenge on Google Chrome developers for messing my day up
9. Decided to try it the manual way, as described at the beginning of this thread, but came up with the error attached. Also, looking at the structure of the database, it doesn't look like it's anything to do with the bookmarks (as in 'starred' items). Like the name of the file suggests, it looks like it's to do with the browsing history only.
10. Decide to try and export bookmarks from Chrome rather than Chromium, as I've only bookmarked a few sites since setting up Chromium this morning, but trying to select the 'history' file in Chrome, SQLite's just saying 'database not selected' in the left pane (despite me selecting it in 'connect database', and if I try 'create view', it's just saying "you must first open a database"
11. Try again with Chrome, but this time try to select the file called 'bookmarks' (logically, you'd think they'd call it 'bookmarks', wouldn't you?). Same error message as in previous step above, that no database is selected.
12. Tried Scaroth's little Java app, after checking I've got the latest Java runtime installed, which according to the Java site, I have (1.6.0_10-rc). Not only is the Java app silent, but I checked my IE favourites, and definitely absolutely nothing has happened at all.
13. Closed everything again and double-clicked the jar file again, just to make sure I did infact double-click it before. For result, see previous step.
14. Give up and sulk because I've wasted virtually all day on this, got no work done, consumed far too much coffee and cigarettes, and contemplate whether to join the Foreign Legion (and infact whether they accept girlies, even if they are geeky girlies
