This is most likely an good theme but too much basic. Just an blue theme.

При раскрытии браузера на полном экран на 2К мониторе, задний фон не полностью расстягивается и появляется тёмный прямоугольник, очень надеюсь, что поправите этот баг. В остальном тема бомба, очень понравилась.

Broken for HiDPI displays. Otherwise good one

I really like this theme but the blue background stops going from right to left about 2/3rds across my ultrawide monitor, so it looks like that background gradient/image isn't long enough for these kinds of monitors.

this theme is the best theme available, contrast and usability is just perfect! but only if your monitor is not bigger than 1920 width though.

i edited the file to fit bigger resolutions, not sure about making it public, don't want to run into copyright troubles.

basically just open the file (google how please), scale the image to 5k, delete meta inf folder, save as zip and release as private in developer page. you get a link from mozilla to install it.

Looks nice but doesn't scale on 4K, leaving an ugly empty space on left third of window.

Truly experimental! Like You will just enjoy the theme on the right half of your browser experimental.

Very nice color combo! On my 1440p display, however, the colors have a harsh line through the middle of the third app and don't extend to the left side of the screen.
