I have to recommend this awesome free program. Its very good, maybe im late with this program, but i really like it.
This program will backup Comodo Dragon (and other browsers) - It will backup and restore Bookmarks - Settings - Extensions and so on. You can also use it to migrate between browsers (as long as they have the same engine) For example migrate between Chrome and Dragon with a simple click, you get the point.
You can make a backup of Comodo Dragon and then restore it later with a simple click.
I formatted my computer and made a clean win 8.1 install and did a backup of Comodo Dragon before i started. I made a restore when everything was finished, and everything is back to normal, all my extensions, settings, bookmarks and so on.
Must have program!
