Nice looking theme. Works even on Big and High Resolution Screens (tested on a 2560x1440 Display). The text contrast in the url-bar could be better. Also it would be nice if the text in the bookmark bar would be more colourful.

Here is a link to my Themecollection:

Perfect, although I would suggest making the toolbar slightly less transparent, as certain extensions seem to blend in, and look almost invisible.

I like the design. Just wish it had a dark mode.
Edit: It has dark mode but I mean when you open a new tab or window it is white if it's set to open Firefox home page aka the default setting.

Nice bro

Looks 👍
