789327 - Copy to clipboard failed - about:config preference signed.applets.codebase_principal_support also failed.

Status: RESOLVED WONTFIX

(Core :: Security: CAPS, defect)

Description

[Charlie]

User Agent: Mozilla/5.0 (Windows NT 6.1; rv:15.0) Gecko/20100101 Firefox/15.0
Build ID: 20120824154833

Steps to reproduce:

signed.applets.codebase_principal_support
added this preference to about:config


Actual results:

It said that I was not allowed to do what that should have allowed me to do.
In other words - absolutely nothing.

Note: We had to go through this process in 14.0, but it resolved the issue there.
When it pops up the error, it takes you to a page explaining how to solve the issue:
http://www.febooti.com/support/website-help/website-javascript-copy-clipboard.html
unfortunately what was a simple fix in 14 now is completely useless.



Expected results:

It should have allowed me to copy items to clipboard (embedded button from web page)

Could you provide a website URL with a button to copy items to clipboard, please.

I will provide info.  

http://blb.org has the button to copy items to clipboard but hasn't worked with the last couple versions of FF.  Here is a link to the method that has been working for years  http://www.blueletterbible.org/help/javascript-clipboard.cfm

To test it out, click on this link and you will find tiny white check boxes next to each sentence.  Put a check mark into the first couple of check boxes and then scroll to the top and click on the check box next to the words "copy options".

http://www.blueletterbible.org/Bible.cfm?b=Jam&c=2&v=1&t=KJV

Normally, if your signed.applets.codebase_principal_support is set to true then the sentences that are checked will be copied to your clipboard.

Thank you! I was hoping someone would post a public site that exemplifies this bug. I couldn't post an example because it's on our intranet. I can verify that the website you linked to works in FF 16.0.2 (what we use due to this not working in subsequent versions).

STR:

1) Set about:config > signed.applets.codebase_principal_support = true
2) Open http://www.blueletterbible.org/Bible.cfm?b=Jam&c=2&v=1&t=KJV
3) Select a white box in the column (e.g. before "Jam 2:1")
4) Select the white box on he right of "copy options"

Result:
Error message:
"Your current Internet Security settings do not allow data copying to clipboard. Do you want to learn more about enabling data copying to clipboard in your browser?"

Insteaf of:
"A script from "http://www.blueletterbible.org" is requesting enhanced abilities that are UNSAFE and could be used to compromise your machine or data:

Suspected bug:
Bug 750859 - Gut unused CAPS code 

Anyway, I'm not sure if it's a valid regression (privileges removed due to security issues).

Yep, we removed support for enablePrivilege and all that stuff. See bug 546848 comment 57.
