Breaks a lot of sites.

I was looking for a resource-friendly alternative to Dark reader, but this addon broke the CSS of a lot of sites. I had to uninstall it again...

It was a very nice experience and I would have preferred to continue using this add-on, if not for the issue that it changed all my background colors to white and it is irreversible.

Extension will NOT turn off on my browser! Options won't respond to turn off features.

I namely installed this to use for sites like rosetta stone and all it did was break the site entirely.

Too black for me :(. And I don't fancy to adjust the colors for myself - this is what I expect from the addon.

This is an essential addon for the internet plague of white or light backgrounds. Unfortunately it stops multi threading and makes all the browsers that I have tried it on crawl to a stop with mind numbingly slow page load times.

I am currently using Cyberfox 52.9.1 with DBLT v0.6.8 the highest supported version. I prefer v0.5.14 because it allows the backgrounds of mozilla and addons pages to be altered but I thought that I would test with the latest supported version to see if multithreading would work, which it does not. No other addons installed so nothing else to blame but DBLT. Help->Troubleshooting Info shows whether multithreading is enabled/disabled.

Loved it, but not to be newly installed any longer on mobile although still working on other devices.

App intercepts website's style sheet and reloads the website twice, slowing it down. While I appreciate being able to change the ubiquitous gray text to black, with today's css-driven design and perennial screen overlays, I frequently have to disable this app.
