Disable Delay Time When Installing Add-on | Firefox Tips
I am in a bad habit of installing many add-ons on my computer and it really agitates me when ever I have to wait for several seconds before the installation begins.
If you too are tired of waiting before the installation of the timer begins, then this tweak will enable you to get ride of that timer in no time. Here is how you do it, but before you begin make sure you made a back up of your registry, to make sure you are on the safe side.
Open your browser; i.e Firefox and type the following: about:config press Enter. In the same window type the following inside the Filter box: security.dialog_enable_delay.

Set the default value of ‘2000‘ to ‘0‘ (as illustrated above). Close Firefox for the changes to take effect and re-open it again. Now you won’t have to wait for the installation to start. Enjoy!
