## How to install
1. Go to `about:support` and click the "Open Folder/Show in Finder" button for the root directory of your browser profile/s.
2. Download and copy the `chrome` folder into the profile folder.
3. Go to about:config and change these preferences:
   ###### For all operating systems:
   1. `toolkit.legacyUserProfileCustomizations.stylesheets` = `true`
   2. `svg.context-properties.content.enabled` = `true`
   3. `layout.css.color-mix.enabled` = `true`

   ###### On macOS:
   1. To use the Edge style context menu on macOS then set `widget.macos.native-context-menus` = `false`

   ###### Recommended:
   1. `browser.tabs.tabMinWidth` = `66`
   2. `browser.tabs.tabClipWidth` = `86`

   Additional tweaks can also be applied to the theme, such as Mica (Windows 11 Only), Floating Tabs and more. See [Tweaks](#tweaks).
