Ghostery allows sites to be permanently white listed so they don't have to be toggled.
As PbGuy already mentioned about Ghostery, instead of allowing
all trackers on a site by whitelisting it (and kind of throwing out the proverbial baby with the bathwater), you can also allow just the problem one(s) for that site
* only. Of course, you'll have to know which tracker is the crucial one to allow, but that's relatively easy to establish, particularly if there are only a few trackers on the site (allow tracker and reload page). If you're a frequent site visitor, it may be worth your while to check them all even if there are more than a few.
If you're also using Little Snitch and/or an adblocker, note that they may be involved in your problem too. When testing the various trackers on a site, you might want to disable those utilities temporarily, unless you're absolutely sure they are not part of your problem.
*) To allow a particular tracker for the current site, click the rightmost button behind the tracker's name in Ghostery's (v.5.x) listing. The toggle is to the left of this button. Hovering over a button will bring up a tooltip explaining the button's action.
