It's pretty good not perfect but good

I like this extension, but could you (the Maker) make it delete colors by default?

Works for me. My eyes says: Thank you.

可以去掉页面颜色。但不能自动去掉，每个页面都要点一下按钮才行，还不够方便

I DON'T LIKE THE NEW BLACK AND WHITE FIREFOX

brutal big icon, horrible, should go back to the previous version !!!

It would be noce it it worked more like the "Blank your monitor + easy reading" addon for firefox.. (Dosent work from Firefox v57...

This app should have a key shortcut and user should be able to change that..
Be able to set a color schemas for background and foreground.. Might also be easier to add to the this add on then the current method since it dosent work properly on Mozillas add ons page...
Also when opening a new tab i have to click once again.. it would be better if it was either on or off..

有些時候於網頁閱讀上很有幫助：）

I cannot find the No Color button in Customize window, therefore no way to enable add-on! It was working at one time but no longer.

I used this for years and really liked it. Suddenly, the "No Color" button is not to be found -- not on the existing menus or toolbars, and not shown as an option for customizing them. So, with the extension installed, there is no way for me to activate its features. ?? I hope that the author will find a way to fix this and continue with No Color.

No way to move button from URL bar, even with customize, and no other button there. Worse, it just removes backgrounds, and no way to customize it (for example, no way to set it to use #888888 gray globally).
