When I SYNC, my bookmarks are still on a work computer, even though I've closed out of Firefox. NO ONE wants their bookmarks to stay around at work.

Question

So, the reason I decided to try Firefox Sync is that I recently discovered that when I sign out of my Google Account, it turns out that my bookmarks were still all there on Chrome on multiple different work computers (I'm an independent contractor & work at many unrelated locations, so clearly, this was a serious security problem with Chrome & they had no way to help it. None. Whatsoever. And it was happening to other users, probably unknowingly)
So, I used Firefox Sync today with a work computer & yep, when I clicked the red EXIT FIREFOX button in the settings, & then reopened Firefox to check, there were all my bookmarks. I do not see a LOGOUT option for SYNC. Just a Delete my account or change my password option under Manage Account or a DISCONNECT option under Options. The Disconnect popup says this: "Firefox will stop syncing with your account, but won’t delete any of your browsing data on this computer."
So, I didn't use the DISCONNECT or DELETE MY ACCOUNT options because when I tried the disconnect option on Chrome, it deleted most, but not all of the bookmarks on ALL of my devices & I would've lost all hundreds of my bookmarks had I not made a copy of them from my non-logged-in tablet.
NO ONE wants their bookmarks available to anyone else who opens the browser on the same computer just because they synced once w/ their Firefox account or logged into their Google account.
If there is NO way to log out & remove the USER-SPECIFIC--NOT device- or browser-specific-- bookmarks & other potentially problematic info, then this should be made CLEAR in an informative article if someone chooses to SYNC.
No one would ever SYNC if they ever used a computer that is not their own if they knew that their bookmark info were left on the browser.
Is there a SYNC logout option that I missed that makes this question irrelevant? I hope so. Otherwise, I guess I'll be emailing a bookmarks file to myself for temporary work use & then deleting it.
If I sign in to Yahoo! or Facebook or any shopping site, etc, when I logout & clear the cache & cookies, etc, like I always do, my info is gone. It doesn't show up the next time someone opens the browser.
I even changed the settings in SYNC to NOT synce the bookmarks, but they were still there when I reopened Firefox.
thanks.

Actually, it's not obvious & common sense would dictate that users' bookmarks would not be left stuck to random computers even once they've logged out of the account. No one wants that if it's a public work computer or if they're traveling & use an Internet cafe. As I am not the only one who has noticed this issue or had bookmarks disappear/be deleted, in addition, common sense would indicate it's not really a very good system. And carrying around a flashdrive to run Firefox off of it is a good solution? Really? Just curious why a useful feature such as being able to login & use your preferences & bookmarks & then logging out removes your preferences when you're gone hasn't been developed. Yahoo keeps my preferences when I logout (it's called My Yahoo!). Maybe a My Firefox or My Chrome solution could be developed.
