I am running Firefox 3.0.10 with the following extensions: XMarks, Ad Block Plus, AutoPager (turned off). I have been having the problem of pages not displaying correctly for some but not all sites. Experts-Exchange is one that displays incorrectly so I've attached a screenshot that shows the repeating text - look at the right column, for instance. I've uninstalled and reinstalled Firefox to no avail, tried inactivating the extensions - no help. This is a desktop running XP SP3. IE displays these pages fine. Anyone know a fix?
