By "auto synchronise", I mean whenever I bookmark a page in Chrome, it should also be bookmarked in Opera's bookmark list and vice versa.
Transmute will convert, synchronize, sort, organize and remove duplicates from your bookmarks and more.
Transmute supports all of the major web browsers including Google Chrome, Mozilla Firefox, Internet Explorer, Opera, Apple Safari, Chromium, Flock and Konqueror!
Transmute is freeware and portable, no installation required.
note: automated/scheduled cross-browser conversion is only available in the Pro version ($20).

One more way to use Google Bookmarks in both Opera and Chrome (and probably any other browser):
- Add a bookmark to Google Bookmarks
1.1 Chrome and Opera both have extensions to add pages to Google Bookmarks
1.2 Or use the 'Google Bookmark' bookmarklet found at the bottom of the Google Bookmarks list
- Add a custom search engine to search for your bookmarks using the address bar. For example
gb bookmarkswill search for bookmarks tagged or named 'bookmark', where
gbis the keyword for the Google Bookmarks search engine.
The idea and instructions on how to create a Google Bookmarks search engine come from here: https://metaed.blogspot.com/2008/12/using-google-bookmarks-in-google-chrome.html
The article describes how to create this search engine for Chrome, but the same instructions work for Opera.
A superior solution, in my humble opinion is having the bookmarks in the cloud. I use Google bookmarks and access it from any web browser or computer and every thing is always synchronized. As for Opera, here's how to use Google Bookmarks almost seamlessly with Opera: http://my.opera.com/abadr/blog/2009/10/31/use-google-bookmarks-with-opera-browser#comments.
