If you're worried about losing Google Sync in Chromium, you might as well use Chrome
I’m a hypocrite. I use the Chromium browser packaged by the Debian Linux distribution. I also use Google’s sync service for my bookmarks. By using the open-source (yet Google controlled) Chromium instead of the proprietary Chrome (which is based on Chromium), I fool myself into thinking I’m adhering to some kind of software freedom principles. I don’t want Google “spying” on me, so I don’t use Google Chrome, which could be a black box doing all sorts of horrible things for Google’s benefit.
