Google-chrome – How to keep Chrome bookmarks up to date

The quickest way may be to get another browser to import the bookmarks from chrome and export the bookmarks from that new browser. However, all such imports require an export from the Chrome Bookmark Manager, which you say doesn't work for you.

You can also use Xmarks to synchronizes your bookmarks using the extensions for both Firefox and Chrome. Xmarks also claims the ability to directly export bookmarks to HTML.

You may also be able to sync the bookmarks to your gmail account and export from there.

From How to Use Google Docs to Transfer Chrome Bookmarks to Other Browsers :

1. Log in to Google Docs and look for your Google Chrome folder.
2. Select the Bookmark Bar folder, which will grab all of the contents within it.
3. Choose More Actions, Export. Leave all of the default settings and continue. Google will zip the contents and your computer should automatically download the compressed file called bookmarks.html.
4. Now that you have all of your Chrome bookmarks from the cloud, simply import the bookmarks.html file into your browser. Internet Explorer, Firefox, Safari, Opera and most other browsers support HTML importing of bookmarks.

I'm not sure about Chrome's internal sync, but you might try XMarks sync. It offers sync between browsers as well as computers across the internet. It supports all 4 major browsers. You can also access your bookmarks from any computer via their web portal, in case you find yourself on another computer and need access to your bookmarks. And if you upgrade to their pay service, you can sync to your iPhone, Blackberry or Android device as well and gain access to their open tab sync, where you can close your browser on one computer, go to another computer, open up the browser and all the tabs you had open will be opened on the new computer.
