Both manual and script installation methods should create a git clone in `your-profile-folder-path/chrome/firefox-gnome-theme`, so the easiet way to update the theme is to open this folder in terminal and perform a git pull `git pull origin master`.
> Note: Running installation script to update after cloning again the repo can work, but also can introduce duplication in CSS sheets.
Open `chrome/firefox-gnome-theme/userChrome.css` with a text editor and follow instructions to enable extra features. Keep in mind this file might change in future versions and your configuration will be lost. You can copy the @imports you want to enable to a new file named `customChrome.css` directly in your `chrome/firefox-gnome-theme` directory if you want it to survive updates. Remember all @imports must be at the top of the file, before other statements.
Alternatively you can run installation script with `-g` flag to auto install GNOMISH features.
```sh
./scripts/install.sh -g
```
*Those features are not included by default, because can introduce bugs or Firefox functionalities lost.*
- **hide-single-tab.css** *GNOMISH*
Hide the tab bar when only one tab is open.
You should move the new tab button somewhere else for this to work, because by default it is on the tab bar too.
- **matching-autocomplete-width.css** *GNOMISH*
Limit the URL bar's autocompletion popup's width to the URL bar's width.
Icons might appear black where they should be white on some systems. I have no idea why, but you can adjust them directly in the `system-icons.css` file, look for `--gnome-icons-hack-filter`&`--gnome-window-icons-hack-filter` vars and play with css filters.
