(Firefox :: General, defect)

Description

[Black_Ps`]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.3) Gecko/20100401 Firefox/3.6.3

a site like http://www.showmyip.com/?version=full can reveal that browsers don't protect people privacy like not showing private information like,
CPU class/type:	OS/CPU Windows NT 6.1 
Screen Width:	1280
Screen Height:	800
Screen Color Depth:	24
Window Width:	1267 (99.0% of 1280)
Window Height:	544 (68.0% of 800) ..etc..etc
I think firefox must block this information or at last ask the permission to access them,i don't see a page i`m visiting must know my private information or what computer i have and where i`m located with a max precision.

Reproducible: Always



Expected Results:  
To block any private information that stupid sites are using it to identify people like a finger print,this is bad very bad..

http://browserspy.dk/ shows all that is possible.

>CPU class/type:    OS/CPU Windows NT 6.1 
That is from the UA, we have a bug about to make it shorter. Please use the search to find it.

>Screen Width:    1280

This is collected via JS/DOM. You can try to get those standards changed.

This bug report is too general to be useful and some things are needed for page designs/functions and can not be changed or removed. 
marking wontfix because we will not remove all the capability and some things are impossible to remove like the IP address.

I did not say to remove ip address

Comment 3

[Tyler Downer [He/Him]]

location and other information like that can be pulled from the ip.

i know,but why do they need to know CPU class/type:	OS/CPU Windows NT 6.1,opera don't permit this thing and it's working fine,and IP Address (via Javascript):	127.0.0.1
Host Name (via Javascript):	localhost

6.1

Read comment #1 ? 
(search the bug about making the User Agent shorter)

>and IP Address (via Javascript):    127.0.0.1
>Host Name (via Javascript):    localhost

And why should that be "dangerous". or a privacy leak ?
