Hello I have read the following info on Firefox Sync but they did not provide me with the info I am searching : :http://support.mozilla.com/en-US/kb/what-firefox-sync#w_thats-enough-explanation-ae-just-show-me-how-to-use-this-thing http://support.mozilla.com/en-US/kb/how-do-i-set-up-firefox-sync https://support.mozilla.com/en-US/kb/add-a-device-to-firefox-sync I use Firefox Sync on my Home PC and my Laptop and I have everything synced (addon, bookmarks, passwords, preferences, tabs, history). I have just setup Sync for the Portable Firefox I am planning to use on an USB drive. It's fine to have my settings and bookmarks synced automatically, however I don't want to have my passwords synced for that Firefox in case I lose my USB drive. I can't seem to not have PortableFirefox not sync my password without disabling the syncing for my other Firefox. Whenever I deselect Passwords in the Sync options on PortableFirefox, that option is also deselected in my other 2 Firefox and passwords are no longer synced also. Is there a way to do that : to select what item (in my case Passwords) I want to sync or not for each of my Firefox? Thanks in advance for any help. Best regards
