Google Sync vs. Firefox Sync

Eagerly installed Firefox 4 and started playing with it. Was immediately disappointed when I realized that Firefox now has its own (competing?) bookmark syncing system. With the amount of content out there I hope to read, I rely heavily on bookmarks, and syncing as well...so that when I switch from my work laptop to personal, I can easily pick up where I left off. (Not to mention of course keeping track of the many archived go-tos.)

Anyway, I don't believe I have to extoll the virtues of bookmark syncing, but why didn't Mozilla collaborate with Google on this? Smells a lot like creeping "lock in" to me, which is not how I thought either of those organizations rolled.
