I got a new laptop and wanted to transfer all my settings. It's easy to use rsync/scp to copy your files, but I wanted to copy all my chromium settgins/bookmarks/history/bookmark toolbar/cookies/passwords/extensions/etc.
First make sure Chromium isn't running on either machine.
The directory that has all the settings is: ~/.config/chromium
.
So, rsync/zip up the ~/.config/chromium
directory on the original machine and then copy it to the new machine and replace the ~/.config/chromium
directory (if it's there). This will wipe all the settings on the new machine and replace them with the old original ones.
