I am also seeing this problem on this page:
http://zh.wikipedia.org/wiki/IQ%E5%8D%9A%E5%A3%AB

The page looks ok when initially loaded. However, when scrolled to near the bottom, most of the characters in the newly exposed area of the page are not showed. If I scroll back to the top, most of the characters that showed before disappeared, too.

My system:
OS: Fedora-12 x86_64
Firefox version: currently firefox-3.5.8-1.fc12.x86_64. The problem appeared in older versions as well.

This problem does not occur with the 32-bit firefox-3.6.2.tar.bz2 package I downloaded from mozilla.org.

This problem can be reproduced in a fresh installation of Fedora 12 x86_64 in a VirtualBox virtual machine.

Both of them are ignored for a very long ... long time ...

Yes, maybe.
Changing the font size or the zoom in firefox does make a difference.

Comment 11 Bug Zapper 2010-04-28 09:38:10 UTC
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11.  It is Fedora's policy to close all
bug reports from releases that are no longer maintained.  At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '11'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 11's end of life.

Bug Reporter: Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 11 is end of life.  If you 
would still like to see this bug fixed and are able to reproduce it 
against a later version of Fedora please change the 'version' of this 
bug to the applicable version.  If you are unable to change the version, 
please add a comment here and someone will do it for you.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events.  Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

The process we are following is described here:

This happens in Fedora 12 x86_64 as well (see comment 7).

Comment 15 Bug Zapper 2010-12-05 06:38:13 UTC
Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.
