I just created Mozilla account to thank you for such great add-on! Background is black and the text is readable! Thanks a lot!

Best for its work

I love and recommend this Dark background and light text extension. I use this with the dark default theme of Mozilla and Black New Tab of Mr. Yoasif. Dear designer behind this fantastic extension, Mr. Mikhail Khvoinitsky, I thank you so much for your worthy and beneficent work. Hats off to you!
