I tried about five to seven dark/night mode add-ons and extensions before this one. They all lacked the intelligent subtleties that must have gone into the development of this add-on. This one has site-specific settings and a white list, and has not caused any visual unpleasantness or stability issues. I have not used it long, but after running a slew of tests viewing various web pages needing a night mode and others I'd like to be exceptions, I have to say that this add-on is head-above-shoulders bettering its competition. Many thanks to its developer. I hope he continues to update this plugin for long time to come.
