Mozilla’s Firefox browser has tremendous flexibility to customize internal settings to make it faster, better, and more productive. However, the plaque of malware has forced Mozilla to add a delay when attempting to install new extensions. Power-users frequently will want to disable this delay.
While installing any new add-on in Mozilla Firefox, it stops every installation with an annoying pop-up dialog box. It takes 5 seconds before the Install button appears.
Mozilla has added this delay to stop users from accidentally installing malware that is masquerading as a browser extension. However, most skilled users are already incredibly cautious about this process. These mandatory pauses can be disabled.
