I noticed that Portable Firefox breaks the Live bookmarks. Also there is another problem. I have gmail and i have the google personal page set 2 my homepage
when i startup Firefox it says sign in button, so i click it and my page shows (didn't prompt for username or password) or if i press homepage again my homepage displays properly. It only happens on pFf startup. If i press homepage toolbar button, my google personal page shows up (it does not say sign it).
It is probably a Ff issue but i only use PFf.
