Hi! hehe, thanks a lot for your attention, I'm glad to see you find it helpful.
I felt guilty, because this first version is actually not a really good one, and the code is ugly. so I made a new one, that is completely language independent, and is encapsulated so that there can be no conflict with other javascript codes on the page.
And also, added comments so people can understand what this does.

the update is available at the same address, http://mikakesensei.com/perso/javascript/fb_expander.js

thanks again :)

Thanks @mdusenne. Very kind of you to put it all in the open.

Hi woodwardtw, the code does work, but it has some issues:

• it does not open all "replies of comments"
• it takes you back on top of the page

The second one is crucial, as I cannot scroll and load older posts. Every time facebook tries to load an old post, the code takes me back to the header, so it is really impossible to read old posts.

Is it possible to fix these issues, it is a great function...

woodwardtw, thank you!
Your code works pretty well!
Can you please include expanding this type of things "*** replied · *** Replies"?

Thank you in advance!
