I've posted about another program that does some of those things in this same forum (it's an old thread and I'm too lazy to go look for it
). Namely the syncing of favorites/bookmarks among several browsers.
So I'll repeat it here:
Bookmark Bridge (http://bookmarkbridg...forge.net/index.html
Quote from its website:
"BookmarkBridge is a small, easy to use, multi-platform, GUI-based utility that allows the user to share bookmarks between all their browsers. The user runs it periodically to synchronize between the browsers."
It's absolutely free and open source. It's supposedly still a beta version, but I haven't run into any problems using it. It hasn't been updated too often lately too, but the latest version seems to work ok with the most recent browsers.
I'm using it for a three-way sync between Opera, Firefox and IE/Maxthon.
I hope you'll like it too.
