WebExtensions can not modify browsers appearance in Firefox 57+

The only way to modify ui is adding custom CSS code to userChrome.css and userContent.css files inside browsers profile folder.
Keep in mind CSS code can not create entirely new items, buttons or toolbars. It only can modify already present ui items.

Where to find Firefox profile folder and what is the correct location for user styles?

1. Find your profile folder ('profile names are different for everyone').

All OS
about:support > Profile Folder > Open Folder
Shift+F2 to open Firefox's command line, then enter the command folder openprofile

or

Windows
C:\Users\ USERNAME \AppData\Roaming\Mozilla\Firefox\Profiles\ PROFILENAME \

You have to make hidden files visible to see "AppData" folder or open "%APPDATA%\Mozilla\Firefox\Profiles\" from explorers location bar.

Linux
\.mozilla\firefox\ PROFILENAME \
You have to make hidden files visible to see ".mozilla" folder.

Mac OS X
~\Library\Mozilla\Firefox\Profiles\ PROFILENAME \ or
~\Library\Application Support\Mozilla\Firefox\Profiles\ PROFILENAME \

2. User styles belong into "chrome" subolder. Create it, if there is none yet.
\ PROFILENAME \chrome\

3. Copy userChrome.css, userContent.css and subfolders into \chrome\ subfolder.

How to use custom user styles?

The userChrome.css and userContent.css files works like an options\configurations file. All main "features" can be enabled and disabled there.
Edit userChrome.css and userContent.css with any text editor (Notepad++ recommended on Windows) and enable btw. disable any feature you like by modifying, removing or outcommenting available "@import..." strings.
Restart browser after every change for changes to take effect.

Example
If you want "classic button appearance" for navigation toolbar buttons, the corresponding line has to look like this:
@import url(./css/buttons/buttons_on_navbar_classic_appearance.css);

If you do not want "classic button appearance" for navigation toolbar buttons, the corresponding line has to look like this:
/* @import url(./css/buttons/buttons_on_navbar_classic_appearance.css); */

Note
/* Code between this lines start and end symbols will be "ignored" btw. "outcommented" */

How to find ids and attributes?

Enable once:
1. Tools > WebDeveloper > Toggle Tools > Toolbox Options > Enable browser chrome and add-on debugging toolboxes
2. Tools > WebDeveloper > Toggle Tools > Toolbox Options > Enable remote debugging

Hit 'Ctrl+Alt+Shift+I' or open 'Tools > WebDeveloper > Browser Toolbox'.

How to modify custom user styles?

Open CSS files with a text editor. Look through the code and change/remove values the way you like.
Some files contain additional instructions to tweak the ui for individual cases.
Restart Firefox for changes to take effect.

Example
Open ./css/tabs/classic_squared_tabs.css file
Look for /* unloaded/pending tabs color *//*
Remove /* at lines end to make that part of the code active. Save the file and restart Firefox.

Example 2
Open ./userChrome.css file
Look for @import url(./css/locationbar/ac_popup_classic_with_two_lines.css);
Add /* at lines start and */ at lines end to remove classic popup.
Look for /*@import url(./css/locationbar/ac_popup_url_and_title_50percent_width.css);*/
Remove /* at lines start and */ at lines end to enable this popup appearance.
