After un update of my system the toolbar element disappeared . I can't change colors anymore :(
Also I never found a way to choose you custom colors. I kept this extension as it was nonetheless the easier solution I fond to do that in Thunderbird.
I love this app. but it won't let me use it on the updated firefox.
Great. It would deserves 5 stars if on loading pages there was no bright flashes with default setting.
I's a nice addon, works as said.
The configuration is not easy - for first -, but if you read the tooltips - as it is suggested in the description - it gets trivial.
One suggestion though: have you considered creating a separate button for the "Apply preferred or default" function? The double click works, but is cumbersome.
Finally, thanks for this great piece of software.

The users are not paying.
It's all very sad.
Very cool. I love 'invert lightness'.
Unfortunately it doesn't work on some pages (e.g. Facebook and SoundCloud): After a while clicking around, the colors become buggy...
unfortunally No black on white/light grey theme and the colors aren´t adjustable.
Update: Thank you
Just click 'Invert lightness', then click 'Scale to lower lightness' once or twice, and then click the 'star' or 'plus' button for saving, and you'll have a light-gray-on-black theme (on most pages).
You may also start from theme 31 and then click one of the 'Shift hue' buttons repeatedly to obtain a gray-on-black theme which retains some of the saturation of e.g. links with the hue you like most.
With Color Transform, you can save only one custom theme. Try Colorific if you would like to save more custom themes or would prefer more extensive customization.
I needed some minutes to set the options the way, that all foreground images are being processed. Now it seems to work, but I miss an often needed function: Gamma correction.
So I'll still have to save images and open them in another image tool... sad.
#open source (Kadu Diógenes):
All source files start with the MPL2.0 header - so what exactly do you mean with "to open source this add-on"?
If I do not want inversion applied to images & videos, how to exclude them ?这个评论是针对附加组件的一个早期版本的（6.0）。
I knew there was an add-on that came very close to inverting the colours like windows magnifier and linux' xcalib would do it. It took me some time to find it because it's not as popular as it deserves to be.
Sometimes inverting the colours for everything on the screen isn't what you need. This is when this kind of addons come in. They only invert what's inside the browser. I've tried other popular addons for this purpose but they either leave some ugly areas and lines uninverted or don't allow you to choose whether you want to invert images as well or not.
This addon fixes both problems. It can invert the webpage colours without leaving those noticeable uninverted parts and also allows you to decide what to do with images. Just what I need for night usage.
I can't comment on the other modes because I mostly use the invert feature (though I was able to get some amazing themes and visual effects by messing around), but I highly recommend this addon for any users of apps like windows magnifier looking for an alternative that only affects the web browser.
Thanks so much to the author! this addon is absolutely dependable
Any way to open source this add-on?
Sorry if my question offends you, this wasn't my intetion. I just loved your extension and becomes very curious about how you done this wonderful work.
I loved it so much that I already made a contribution.
I have some ideas that I would like to try and your extension already does a bunch of work that I will probably need, so my interest.
Indeed I respect your business model, but if you were thinking in open-source it, or even already have it available somewhere, how could I know?
Great add-on - really helpful for making colour changes to minimize eye strain from reading text.这个评论是针对附加组件的一个早期版本的（4.9.3）。
Bad news: It's worst that Deluminate in Chrome!
Long story: I've done some intensive testing on all available add-ons in FF (and chrome). There are about 5-6 "night readers" on each. In general, the "inverters" in FF (unlike chrome) are all a bit worse in tems of not breaking the websites (i.e unusable for default browsing). So the only solution is to use a "themer", the best of which is this (Check Theme 10)! And if you need additional contrast, apply an inverter on top of it (It works (eg. Aniverto)! Or a web-site specific themer, It also works (eg. Black Google)! If you don't like this due to low contrast, your only other real option is to use "Screen Dimmer" but this is way better and in my experience it is the ONLY viable alternative in FF. Without it, I would have no option but to revert to chrome. So, thank you dev!
PS. If you can do the impossible and increase font brightness a bit or at least do some magic with the plague of "bright flashes on loading" (that plague both chrome and FF for ages!) that would be 5+ stars!! Ratings are based on eye-strain!!

Хорошо, что дополнение работает только в пределах текущей вкладки, а не всех, как это делает дополнение "Blank Your Monitor + Easy Reading". Однако, там есть настройка горячих клавиш, чего нет здесь. Весьма неинтуитивный интерфейс. Предпочел бы, чтобы стандартных вариантов 10-й и 16-й темы было больше. Upd. Версия 4.9.3 под указанный сабж перестала сохранять пользовательские цвета. А из предлагающихся нет нужной (темно-синий фон, светло-желтый текст).这个评论是针对附加组件的一个早期版本的（126.96.36.199-signed）。
None of these issues matter, because you don't pay and I don't care.
I have been using a much improved and fully functional version for more than a year now, but I cannot release it, because the current version has not been paid for yet.
I only wanted to invert the color. I did it by clicking
1. LIGHTNESS: invert
2. FUNCTION: save
Now after every reload, it automatically inverts the all colors, even better than BYM addon!
Alleged to work with Firefox 24 and up, but not compatible with Firefox 28 Mac — no toolbar button, therefore not usable at all. Like quite a few Firefox add-on developers these days, this gent has not bothered to test his brainchild properly.这个评论是针对附加组件的一个早期版本的（188.8.131.52-signed）。
Thanks for reporting. You'll understand that not all developers have enough time and/or money to test on all combinations of platforms and applications. They would be helped with more user feedback. All I can see in the add-on statistics is that 7% of the current users is on a Mac and about 10% is using a Firefox version older than 29.
I have encountered other add-ons that caused issues with toolbar buttons in the past. Before Firefox 29 was released, every add-on had its own code to manage these buttons. A solution would be to install Firefox Developer Edition besides Firefox 28 and to use it to test or use add-ons that require (or work better) with newer versions of Firefox. This should be unproblematic because the Developer Edition has a separate user profile.

You are encouraged to compose your own default theme using the basic HSLA transformations.
> The user informed me that he would like to impose certain text or background colors on input elements.
'Color Transform' and 'Colorific' cannot target elements of a specific type. Your best bet is to add specific CSS rules using e.g. 'Stylish', 'User Style Manager' or 'Color That Site'. Given that input elements normally don't contain background or foreground images, it should be possible to obtain a readable result.
> The user informed me that the lack of contrast in most themes led to e.g. indiscernible rating stars.
Color Transform and Colorific are not meant for contrast enhancement, but mainly for darkening pages in order to reduce eye strain in dark environments. However, Colorific's single-spectrum themes retain quite a lot of contrast, while e.g. a mere brightness inversion in Color Transform retains all contrast.
The deeper reasons for the reduced contrast in most themes of Color Transform and Colorific are the following:
Background colors cannot simply be set because they need to be matched to background images. Images require non-constant transformations in order to retain contrast. These transformations are always narrowing down the range of colors if they are to have a similar effect on both bright and dark pages. It is not possible to determine whether a page is predominantly bright or dark without rendering it, and even after that it is hard to estimate. In addition, it is impossible to determine whether text is shown on top of one or more elements which have a CSS background image. Hence it is safe to set text and background colors directly to values with high contrast only if one also hides all CSS background images. In most cases this is unacceptable, because these images have many uses on modern pages as icons and other art work.
