by default initial display is hidden on page load

Hi Team
This plugin is very nice but getting one issue with firefox browser right now.
on HOME page
I have html horizontal tab format ,
in each tab there is HTML tables
and each table initially i display first five <tr> and then display load more button, this is working fine for each tab.
But when i jump to other page like about, contact-us etc. and then back to home page my first five <tr> not display by default.

but on chrome its working fine.
