I’m using Mozilla Firefox since 3 or 4 months ago. Since that moment, I’ve been looking for an extension that let me share my bookmarks between my desktop and laptop. After looking a lot of time for it, I found the solution.
The solution is “Bookmarks Synchronizer” by Torisugari. This extension allows you to upload an XML file with your firefox bookmarks to an FTP and then, just download, merge and upload them from any Firefox with this extension installed. Just perfect for what I was looking for.
From the moment I start using it, I have all my bookmarks available from any computer, and at the same time, it is a backup of my bookmarks if my computer crashes.
