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.

I've been using this for probably five or six years! Love it love it love it! Dark reader is horrible and this one always works

First thing I install

Currently using this on my Android phone. Awesome for browsing at night/low light situations and also saves battery on my amoled screen. Thanks!

An option to export/import settings or sync across devices would be nice. However, for anyone looking to manually export the settings to a new device, the settings are stored in the following location in your profile folder: \browser-extension-data\jid1-QoFqdK4qzUfGWQ@jetpack\storage.js

constant white flashes. defeats the purpose and slows things down.

Saves my eyesight thank you

Flawless. thanks.

Excellent add-on! Congrats and thank you to the Dev.

I tested all possible add-ons available for dark themes.
I also tested lot of dark theme scripts (Stylus and similar).
Also tested lot of CSS' scripts at userContent.css.
And this add-on is the best one among other alternatives. It has the best gain/loss equation (lightweight = low system impact, average good web-page layouts etc). In brief, it will work fine for most of the websites.

Sadly, this add-on has two week points:
1) At least 50% of web-pages have a white-flash when loaded, reloaded etc
2) On "Style-sheet-processor" option, at least 30% of web-pages break (for 1 second) at the very beginning when they start to load.

I found these two problems above almost in every similar add-on.
Only CSS' scripts and Stylus' scripts etc eliminate white-flashes + web-page broken on loading. It will be a dream if the Dev (Mikhail Khvoinitsky) can solve these two issues.

Thank you in advance!
