# firefox-user-chrome-css
|
|
|
|
## Overview
|
|
|
|
The `userChrome.css` presented in this repository will turn the "floating"
|
|
browser tabs in Firefox introduced by the Proton UI back into regular "tabs".
|
|
The following screenshot demonstrates this:
|
|
|
|
|
|
|
|
The primary source for creating the userChrome CSS was the generator provided
|
|
here:
|
|
|
|
- <https://www.userchrome.org/firefox-89-styling-proton-ui.html>
|
|
|
|
The resulting CSS was tweaked by me manually and then processed with Stylelint
|
|
to apply best CSS practises:

|
## Requirements
|
|
|
|
1. Activate legacy user profile customizations:
|
|
|
|
- Run Firefox.
|
|
- Open <about:config>.
|
|
- Search for setting `toolkit.legacyUserProfileCustomizations.stylesheets`.
|
|
- Set value to `True`.
|
|
|
|
2. Locate your Firefox profile folder:
|
|
|
|
*Note:* There are multiple ways of locating your Firefox profile folder; this
|
|
one should work on all platforms.
|
|
|
|
- Run Firefox.
|
|
- Open <about:support>.
|
|
- The value of "profile directory" is the location of your active Firefox profile folder.
|
|
|
|
## Installation
|
|
|
|
3. Create new folder `chrome` in your profile folder.
|
|
|
|
4. Copy `userChrome.css` to folder `chrome` in your profile folder.
|
|
|
|
5. Restart Firefox to apply changes.
