865366 - Copy&paste web text should not include hidden text

Status: RESOLVED DUPLICATE of bug 504748

(Firefox :: Untriaged, defect)

Description

[Daniel Mota Leite]

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:20.0) Gecko/20100101 Firefox/20.0
Build ID: 20130326150557

Steps to reproduce:

go to the http://thejh.net/misc/website-terminal-copy-paste
select the aparently git clone line and copy it
go to a text editor and paste it


Actual results:

It should paste what the user see, the git clone, instead we get hidden text


Expected results:

Just like bug #39098 (that is closed) , copy should not copy hidden text... in this case the hidden text is off screen, should not be copied. I dont know if other hidden techniques (like CSS, font size and color) work 

please note that linux have both the PRIMARY (select and paste) and the CLIPBOARD (normal copy&paste), both should exclude the non visible text

This could be a local client security problem if the user is copy&pasting command, trying to debug or fix something (many times as admin/root users), but he info is already public, no need to lock it up

DUP of Bug 504748 - Web sites can make Ctrl+C copy something other than what it looks like you are copying
