Disable Add-on Install Delay

Disables the add-on installation delay ‘count-down’ safety feature.

Compatibility

Works with: Firefox 3.6+

Background

Having to install add-ons one-by-one is a time consuming process as it is, but to having to wait 3-seconds before you can click that install button adds up. This is suppose to be a security feature, which I can understand for the first time someone goes to install an add-on

The Tweak

To disable this feature:

1. In a new tab, type about:config in the address bar and press enter
2. (If needed) click the I’ll Be Careful button
3. In the filter field enter security.dialog_enable_delay
4. In the preference list double-click on security.dialog_enable_delay
5. In the dialog box enter 0
