Need script/plugin to select link until all web page comments displayed

[Carl]

Brief summary: I need a script/plugin for Firefox that selects the
"load next 25 comments" link at the bottom of a web page, until that
link is no longer on the page. As you click that link - you get more
comments - eventually all of them on the same page. See this web page
for an example (there are 1,852 comments):
http://www.cnn.com/2010/US/05/16/gulf.oil.spill/index.html#comment-50598247

I have a regular problem with CNN.com. I post comments there. People
sometimes reply to them. I check my profile, and see the number of
replies, but I can't read them there. I have to follow the link to the
original article. The fist set of comments are at the bottom, with a
'load next 25' link at the bottom. There are often hundreds of
comments, and sometimes a few thousand. There is no practical way for
me to read the replies to my comments. If there's under around 300
hundred, I'll just click that link enough times to see what the
replies to my comments are. I need a script/plugin to select that
'load next 25' link until that link is no longer present on the page.
Then I could just search for my userid and read the responses.
