Everyone loves Firefox because its wide range of plugins or extensions to choose from. Wondering where to look for Alexa ranking plugin or anything under the sun; you can always find them in its large repository over at Firefox Add-On.However, when you install a Firefox extension, you get a four seconds delay before the Install button becomes active and that's a problem for most, but you can solve this problem by follow the steps below to remove it.

First I point out that this install delay is incorportated in the extension installs because it is a security fix for a firefox bug.

Firefox's solution, from bug 162020, is to delay enabling the "Yes"/"Install" buttons until three seconds after the dialog appears. I believe that this is the only possible fix other than completely denying untrusted content the ability to pose the dialog. Unfortunately, this fix is frustrating for users who install extensions often.

Some users have been intentionally lowering the delay to 0 seconds, which frustrates me. These users think the delay was added merely to force everyone to read the dialog. I surprises me that these users were not able to figure out the security hole given the fix.

The more firefox extensions you play with, the more you want to remove the delay and more prone you are to the security issue.
