Problem

Use Firefox to browse the Web, for this address:

Http://www.jb51.net/article/25192.htm

When you want to copy one of the caption text, you get a hint:

Your Firefox security restrictions limit your clipboard operation, please open ' about:config ' to ' Set Signed.applets.codebase_principal_support ' to true ' and try again, The relative path is the Firefox root directory/greprefs/all.js

"Resolution Process"

1. Then Firefox, open:

About:config

The result comes with a warning prompt:

Of course we continue to do it.

2. Then found:

Signed.applets.codebase_principal_support;true

So, obviously, this is already set to true.

So there's no need to change it anymore.

3. Then go to the Firefox root directory:

D:\Program Files (x86) \mozilla Firefox

And the results were not found.

/greprefs/all.js

4. Restart Firefox now, then go to the website and try again.

As a result, you will still be prompted to copy the title text.

Summary

So, the conclusion is:

It seems that this site, more special, do what the hands and feet, prohibit others to copy its contents.

Therefore, although Firefox itself has been changed to the corresponding configuration, for other normal sites, can be copied content, but for this special site, there will still be a corresponding hint.

So, there is no need to bother with such special websites. Does not affect the use.
