The users are not paying.

It's all very sad.

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.

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.

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.

UPDATE
> 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.
