Here’s a list of useful background dimmer addons for Firefox which you can use to dim backgrounds on website when viewing videos so that they are more enjoyable to watch. Having a bright background around a video isn’t very appealing, because it puts extra strain on the eyes. To enjoy a video more, you’ll have to dim everything down so that nothing distracts you from watching the video.

That’s exactly what the addons that we’re gonna talk about are for.

Turn Off The Lights

Background Dimmer Addons For Firefox (1)

Turn Off The Lights adds a button for dimming everything in the addon toolbar. Clicking on that button while watching a video in a tab down below will dim down everything around the video, see image down below.

It’s a classic background dimmer addon, and it works great no matter which website you’re on. This means that you can use it on other websites, not just YouTube. Wherever there’s a video frame it’s gonna be detected and everything around it is gonna be dimmed after you click on the button.

Get Turn Off The Lights.

Screen Dimmer

Background Dimmer Addons For Firefox (2)

If on the other hand you don’t like the fact that the entire screen is bright when watching videos, then you might be interested in a screen dimmer that dims the entire screen.

That’s exactly what this extension which bears the same name, Screen Dimmer, does. It will dim down everything within all the active tabs, no matter what you might have open inside of them. Use Ctrl + Alt + + and Ctrl + Alt + – to adjust the level that the tabs are dimmed, or use Ctrl + Alt + 0 to reset the levels to normal.

Get Screen Dimmer.

Vimeo Dimmer

Background Dimmer Addons For Firefox (3)

Vimeo Dimmer is for all of those who might be interested in dimming background on Vimeo videos specifically, if it’s not working with Turn Off The Lights for example.

Everything works pretty much the same like with Turn Off The Lights. You get a toolbar button which is gonna turn off background on all the videos, no matter if they’re on a single video page, channel or group page.

Tube Enhancer Plus

Background Dimmer Addons For Firefox (4)

Tube Enhancer Plus on the other hand is a full-fledged YouTube improvement suit that has a wide range of options for tweaking YouTube, one of which is the background dimmer.

After installing the extension, you’ll be given a toolbar down below with options for managing YouTube. There’s a light bulb icon which after you click on it will dim down the video background and at the same time also increase the video player to fill out the entire page, so that the video is more enjoyable to watch.
