Hi SVS,

Sorry you have had this bad experience. And you rated 3 stars for this.

There are many ways to change instantly the current opacity of the dark layer, one of the options is using the Double Click menu. See this YouTube video tutorial:

And if you want a slider bar on top of the dark layer, you can enable this on the Turn Off the Lights Options page. Called the "Dimness Level Bar", you can find this in the Advanced Options tab.

Everything can be customized to your personal style, that from the opacity, color, effects, etc. in the Turn Off the Lights Options page.

About the slowest, do you other any other browser extensions in the background. That can be caused by this slow response. Try to disable that one by one except Turn Off the Lights. That must solve this problem.

Also, if you found a bug, please report it on the support page. And explain how to simulate that bug.
