Works well on Ambiant-MATE-Dark theme on Ubuntu MATE 17.10.

Does exactly what you want it to

Works, but doesn't look super pretty.

Works, though it sometimes takes a long time (maybe up to a couple of minutes) to kick in. For a little background, I'm on a mobile connection so my latency is awful, and pages reach a usable state long before they finish loading. I'm sure this must be some kind of WebExtension restriction, but if there's any way you can fix it I'd be grateful!

Made my sites work like a charm again :)

Thanks

Essential for some users including myself. Too many websites are just too difficult to read without this extension.

... works perfectly on Linux KDE plasma-breeze 5.10.5 (dark theme) and so it solves problem of unreadable text in login tabs as those in new GMail and Red Hat Bugzilla.

This has been driving me nuts. Can't thank you enough.

Does exactly what I need, silently, no fuzz. Just perfect.
Hopefully maintained for future FF releases . . .

Thank you, monochrome101 !

Greatly improves in many cases, has some bugs, but developer is helpful. Dont understand why we need an addon for this..

This is just what i wanted. Though still not perfect in some cases

This is my favorite extension great Thanks... ❤

XFCE desktop with Vertex-Dark theme.
Add-on fixes display elements nicely without resorting to editing CSS.

It works on most of the websites. I'm currently using gnome3/Ubuntu 17.04. When writing review, textbox and text both were black!

Thank you very much. This addon works as expected and fixes a severe issue with my KDE dark theme.

Thanks you for this outstanding Add-on. Working perfectly without any difficulty,
