They were there last time I logged in, but now they're gone. Both the ones at the top (My Account, Post Books, My Bookshelf...) and the ones in the middle (Books I've requested, En Route to Me, Books I've mailed...) Any one else having this issue? I'm using Firefox 3.6.3 --Thanks!  Barbara

The tabs on "my account" main page are still there.  I'm using Firefox 3.5.5.

Hmm...I just checked and my SwayADVD tabs are still there. I've been playing with my cookies lately (blocking those pesky tracking ones) Could that be the problem?

Well the "En route to Me" and "Books to Be Mailed" tabs might not be there if you have no activity.

I just marked a book received today that ended any activity I had ongoing, so the tabs aren't there now.

Yes, I have stuff coming and going. The words are still there, but they are bullet listed (see below). They don't have a link when I hover over them with the cursor, but I found that I can click on them anyway (which is good!). The missing tabs on the top are similarly bullet listed, but they have a link shown when I hover over them:

The tab graphics come from a different domain. The list was in the January newsletter. Make sure that you are allowing traffic to/from all of these domains:

www.paperbackswap.com
secure.paperbackswap.com
a.pbsstatic.com
b.pbsstatic.com
ca.pbsstatic.com
cb.pbsstatic.com
cc.pbsstatic.com
yui.yahooapis.com
cd.pbsstatic.com

You can also try a hard refresh: press ctrl+F5.

Thanks, all,  for all your advice. Cathy, I did check and didn't see any of those listed as "blocked". Then I re-chose "accept 3rd party cookies", loaded the pbs page and the tabs returned! Now to play and see if I can keep my tabs but still code my computer to deny 3rd party cookies.  Thanks again!
