Iceweasel's copy/paste behavior

["Patrick Wiseman" <pwiseman@gmail.com>]

Hello:

When I copy text from a webpage in Iceweasel, the pasted text includes material not visible on the page (because styled 'display:none').  Other browsers (Opera on Linux, Google Chrome on Windows) simply paste the visible text.  Is there any way to tell Iceweasel to do likewise?

Thanks
Patrick
