Are there ways to style or modify the Firefox tab group window?

Theres the chrome://browser/content/browser.xul for the main browser window, which can be inspected using the DOM Inspector and then adjusted in the profiles userChrome.css file.

I would like to do to do something similar to the tab group window (CTRL+SHIFT+E) but could not find any info how to open it in a tab or access the DOM in any other way.

Did anyone do this before? Is it even possible that way or would I have to dig way deeper?

The tab view is an <iframe> element displayed on top of the usual browser content, its address is chrome://browser/content/tabview.html. However, opening that in a new tab won't do you any good - it doesn't work in a tab. Instead you can inspect its contents while the tab view is open. If you have the DOM Inspector extension installed, open DOM Inspector first and switch to browser window to the tab groups view then. In DOM Inspector select menu File / Inspect Chrome Document / Group Your Tabs. That's your browser window (browser.xul), you still need to find the right <iframe> tag. For that search for the tab-view ID. Once you've found the <iframe> tag you can expand it and inspect the structure of its document.
