Nice list of tools. I plan to look into the synergy software.

While I do use Firefox, Internet Explorer is the companies preferred browser, and I also like using Opera/Chrome at times. To share bookmarks between browsers and computers, I use the free web based bookmarking tool Linkagogo. Bookmarks can be kept private or shared.

I too use FastDial on Firefox but when I want to share quick dials between browsers, I use Safari Dial. This web based quick dial tool provides 9 quick dial boxes. Just make it your home page on each of your browsers and you have the same 9 quick dials. I admit 9 is a little limited for me but you just need to pick the nine most important links.
