Firefox: Disabling the Extension Install Delay

In a previous blogpost I wrote about my favorite Firefox extensions. One thing that annoys me though, is that whenever I try to install an extension, Firefox shows a dialog box, and grays out the “install” button for three seconds, like this:
Extension Install Delay

Naturally, this is annoying, but easily remedied. To do this, you need to do the following:
1: In the Firefox address bar, type “about:config” and hit enter
2: Click the “I’ll be careful, I promise!” button
3: In the Filter text box, enter “security.dialog_enable_delay”
4: Change the value to 0

Having done this, you’ll find that the delay no longer appears.
