When accessing certain websites, like a forum that contains mix contents and ads, having just the addon there enabled but not turned on dark mode already can cause memory leaks. Eg: https://forum.lowyat.net

This is tested on Linux, unsure about other OS. Other websites should do fine...

I prefer Dark Background and Light Text by Mikhail Khvoinitsky: https://addons.mozilla.org/firefox/addon/dark-background-light-text/.
You should try it. There are some obvious differences. And then some:
- It works with internal Firefox pages.
- It works with Windows High Contrast theme.
- It doesn't break any add-on pop-up panel.
- On facebook, it preserves original site icons.

Probé con varias otras extensiones y todas eran lo mismo, cambiaban a modo nocturno todas las páginas, algunas se veían bien, otras no, pero con este addon no tuve ese problema, sencillo, eficaz y eficiente.

I have tried quite a few that will darken the screen on some pages but won't on others. This one is the easiest by far and seems to work seamlessly. All the "features" i.e. allowed to write whitelist, the button to turn on and off makes this one above others. Thanks!

It works well, but usability-wise it's not great. I find the toolbar button rather unintuitive (I understand the logic, but the orange looks like it's on even though it's off) and all the preferences should be available through a popup from the toolbar button, especially the whitelist (shouldn't it be called blacklist), so I can see changes immediately.

I've searched for this for soo long and finally found this wonderful Addon. It does exactly what I always wanted and even more! The options are insanely good, the addon itself is very fast and works almost with every site!

One thing that I would love to have is to "blacklist" a site again when you have the site whitelisted with just a rightlick. Now you have to go to the addon settings and remove the URL (Right click --> "Exclude from Dark Mode").

Thank You very much!

Do exactly what expected with simplicity. Perfect !

Just the best and only global dark theme over there

daily user here, so nice so good :D
only activated on sites with bright theme

This is an absolutely extension, if not the best for night workers. Especially for people who are afraid of eye strain with what white web pages can give you. I would like to see a better button to click that gave me a more clear understanding of when it was on or off. But that's ok. A big thank you for this extension, this is definitely worth my donation soon enough. 10/10 You made my day, and my life :) Thank you!

Great addon, thanks!

Nice add-on.

Please, put an option for hide entry in context menu.

update: it is causing sites to crash or slow down (ebay) even if not turned on - so i have do deactivate it (tested with FF55 Win10-32bit)

could you please add a dark theme to the Firefox pages (blanc page, addon page, etc...) too?

some elements may disappear with dark mode on
works not on every page (addons.mozilla.org)??

overall it is a nice, small and easy to use addon. (i´m using the dark grey theme)

Thank you

My fav so far is #10 dark mode (twilight dark)
It could be nice if we'll be able to switch modet in a contextual window on the button itself

Dark mode should be available on all sites. This addon fixes the problem.

Many I've tried, but this takes the top spot for me.

wow amazing works fantastic I can change colors Thanks for this beautiful Add-On Web Extension....

Sorry to report here, but the reporting form on your fails to submit every time I hit 'Send' and just says Contact Admin.

When DM is active on flickr pic pages, the pic does not appear, but does when DM is switched off.

I've also noticed the header background image disappears on some web sites when DM is active.

Not a great problem as you have been clever enough to place the on/off switch on the toolbar for quick access.

FF 55: the checkboxes for theme selection are not visible

Nice theme, thank you!

I really like this app. One more thing would make it perfect : change the Firefox "browser theme" to a designated dark theme when a dark "page theme" is activated.

That would be great for the eyes.

Thanks for your work!

Love the custom style for all commonly-used pages.

Good! Thank you!

Unfortunately also the videos became darker with all styles.

EDIT: New version 0.1.2 and style n.5 fix the video problem.
Thanks.
