Works perfectly as described

Oh, dude, you saved me and my nerves! I'm using KDE5 with breeze-dark theme, and I get almost on every site white input background with extra-light gray text. Thank you!
BTW, where's your PayPal? I'll donate you a cup of coffee, if you drink it ;-)

Excellent , résout tous les problèmes avec les thèmes dark sous XFCE.

You are my heros ! Why isn't it default for FF. That's beyond me. Thanks a lot.

THANK YOU...

Really need this. Save me. Thank you very much.

This solved my problem of using arc-theme on Ubuntu 16.04. Thanks so much!

Works! Thanks!

This virtually completely fixes the dark theme problem...except in the form I'm typing this in, because Mozilla is ridiculous about this issue. They blame web developers for this 15+ year old bug, and then make the same mistakes in web development. Since they don't seem to want to fix Firefox, this addon WILL.

Also works well on Windows with a dark theme applied. Thanks!

Works pretty decently.

Oh sweet irony, I was about to write how much this improves my firefox experience (which is true) and then noticed it doesn't work on this site XD It already helped me a few times, but writing a review is still light grey on white and basically unreadable without selecting the text.
