Is it safe to use Firefox Sync and sync bookmarks and password to portable firefox? And is it safe to save passwords? I do not want passwords and etc. stored or somehow is accessible at local computer.

You can sync to Firefox Portable. But you should set a master password to secure all your passwords.
Sometimes, the impossible can become possible, if you're awesome!
