For those of you who use Mozilla Firefox, you must’ve noticed the customary 2 seconds delay while installing plugins. This may be useful for new users, but for experienced users and developers, who install a lot of plugins for testing purposes, this automatic delay just serves to slow down work.
To disable the compulsory delay, type in
about:config in the address bar. If you are editing the browser variables for the first time, select “I will be careful, I promise!”. In the filter field, type in
security.dialog_enable_delay. Double click on the entry to modify it. Enter the delay time value in milliseconds. If you want to disable the delay completely, enter 0 as the value.
Now you’ll be instaling plugins without any delay.
