Eric,
I just updated my FF. You turned "OFF" the ad blocker? How do you do that?
Thanks.

In Firefox you have to go get an add-on called NoScript (there may be others add-ons that can do the same thing). It will automatically block all scripts, some sites and some features of some sites require scripts to run/work correctly so you will have to selectively run the scripts by clicking on the add-on's logo (or the bottom bar if no script is giving you one) and selectively re-enable some scripts till the site works. I do 'temporarily allow script...' until I know which scripts a site I frequent needs to work, then permanently allow the ones needed.

AFAIK Firefox does not come with a built in ad blocker on the standard release. Your ad blocker, if you have one, should be some sort of add-on, clicking it's logo or perhaps right clicking and selecting it's entry in the menu that pops up should give you options like 'disable on this site' 'disable everywhere' 'enable', etc.
