Rated 3 out of 5 stars

Currently, the font or text color of a new mail window, for the "To / Cc / Bcc" fields needs to be more readable, especially when many are color blind to red.

The "Subject" field box, please change the text color to black, the default color. It is very hard to read with a grey or light grey, which is a bad choice for accessibility - readability reasons.

Text Shadow for the toolbar add-on. Again light text color with white text shadow make it very hard to read. Lessen the spread of the text shadow, use darker shadow color with the light text color. You can also use Text shadow to create a text stroke (see here for the info: https://css-tricks.com/adding-stroke-to-web-text/ ).

Dark text color to light backgrounds and Light text color to dark backgrounds is the best for correct readability and contrast.

Basically make things easily readable in all cases, it will look far more professional.

This fix can either come as a feature so we can change the text color or you can reset it properly in your next update.

Thanks
3 stars because of this issue.

This review is for a previous version of the add-on (1.9.3). 

Are you using an alternative theme? Identity Chooser works very well with the default theme. If you need to change the color for an identity you can do this in Identity Chooser's setting which you'll find in Thunderbird's addon manager.
