aol webmail extension-can not add domains

[steve161]

First post-great extensions-thank you.  For my mail.com account, I
have recently used the beta version of the aol extension with no
problems, but yesterday and today (just re-installed), the extension
has no domains listed, and does not allow adding domains.  I tried the
latest stable release, and ran in to the same problem.  Since I see no
other posts about this issue, I assume it is either something in my
thunderbird (ubuntu 10.04-TB 3.1.7) or a temporary glitch in the
extensions.  Any advice is appreciated.  Thank you.
