This is very strange. I am not having any trouble getting selecting and following these links.
Your site is down for me, too.
This link:
http://yannickcorner.nayanna.biz/freeware-database/
returns:
Server not found
Firefox can’t find the server at yannickcorner.nayanna.biz.
Check the address for typing errors such as ww.example.com instead of http://www.example.com
If you are unable to load any pages, check your computer’s network connection.
If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.
Oh, I see. I was looking at the example links once you got to my site. Not the ones on the plugin page. Sorry about that. Links have been updated now.
