It could be.
Noscript needs two whitelist entries for Yahoo mail.
The first one is
yahoo.com so you alreay have that one.
The second is
yimg.com. Both of these are whitelisted by default in noscript so Noscript should not be the issue, unless you have removed those whitelist entries before.
If Adblock Plus is causing this it should be possible to check.
Go open one of your mails. Then open the Blockable Items list you see here:
http://adblockplus.org/en/tips?tip=effective_filter
Either by left clicking the toolbar icon or pressing ctrl+shift+B.
You should have 4 columns showing, the one called
Filter is the one showing you which ABP filters are currently in effect.
You can then try to disable them one by one. Just doubleclick on a filter shown to be in effect, then you should have a window popup and automatically focus on the filter you doubleclicked. Then you click on the green button like in the this picture:

Afterwards you click OK, and reload the the yahoo tab to see if the mail is visible.
Once you are done and found the filter causing this trouble, you can go to the window with the green buttons and delete it by right click and choose delete. Be sure to enable all the other filters you might have disabled, this is done the same way as when you disable a filter.
