This is by far the best FF add-on I have, and it was just added a few hours ago. Nothing online is as important as being able to comfortably read and view images when browsing. If your eyes get hurt/strained it not only impacts your browsing experience but it can mess with your eye health long term. This add-on is allowing me to surf at night with minimal to no room lighting and not be blinded when a normally overly white page loads. I have just begun to play with the wide range of customizable options available. I am feeling a donation is heading to a dev after I play with this a little more and learn how to best use it.

Worked great without any problems until Firefox 8.0.1. Now it crashes randomly and has to be disabled and re-enabled to work again.

This worked really well for some websites and didn't work on others. There were some issues on some websites where it worked too - for instance if you open a video on youtube it was able to convert it to dark mode, but it wasn't able to change the font color of the channel to a different color which made it practically invisible as black on black.

Addon is perfect but with dynamic theme i have slow page load on youtube and blog with vbulletin. The others themes dont work correctly. For example in yt when i have change to filter or filter+ the left bar words, dissipated. In all other sites i have not problem. Please make something about dynamic theme.

This addons/extension is very good for my eyes because makes the websites dark so my eyes is not hurted anymore.

Useful add-on, thanks!
Please make it change toolbar icon color depended on current page status (Dark Reader on or off for the site).

It works. And it often makes websites look better than the official dark theme. Easy to switch off on a per-website basis when something is obscured. The UI for that isn't obvious though (you have to click the website name in the Dark Reader box).
