提示错误：

"DevBoi: Prototype JS Reference (1.6.0.1)" will not be installed because it does not provide secure updates

 

By default, Firefox 3 prevents users from installing any extensions that do not offer a secure connection for automatic updates.  This prevents users from being victims of hijacked update URLs.

But for developers or people installing extensions they know they can trust, it is a pain.

Luckily it is easily disabled by:

1. Enter ‘about:config’ into address bar, hit go
2. Right click somewhere in the list of keys below.  Select New->Boolean
3. Enter ‘  extensions.checkUpdateSecurity ‘ as the name
4. Select false as the value
5. Reattempt installation of your plugin.
