what im looking for is a program that can merge two files together, so that the end result is one single file with all the data from both merged in.
i need this because i use both my laptop and desktop pc for the net, and i end up with two set of bookmarks. im using firefox, so i cant copy all my favorites like IE.
any recommendation would be appreciated, preferebly for a free product. thanks

Do a Search for the file bookmarks.html on the drive where you run Firefox from.
Copy that over to the similar Firefox location on the other PC/laptop or import.

mozilla or firefox importer/exporter tool

Will these methods allow me to keep what bookmarks i already have on my laptop, as well as get the new ones from the desktop??

No, it'll overwrite what you already have.
