Firefox GNOME theme

A GNOME theme for Firefox

This theme follows lastest GNOME Adwaita style.

` *optional* - Set custom Firefox folder path, for example `~/.mozilla/icecat/`. - Default: `~/.mozilla/firefox/` - `-p ` *optional* - Set custom profile name, for example `e0j6yb0p.default-nightly`. - Default: All the profiles found in the firefox folder - `-t ` *optional* - Set the colors used in the theme. - Default: Adwaita. - Options: `adwaita`, `maia`, `yaru`. ### One command curled script You can also install this theme with one command: ```sh curl -s -o- https://raw.githubusercontent.com/rafaelmardojai/firefox-gnome-theme/master/scripts/install-by-curl.sh | bash ``` It will download the latest version of the theme and run the auto installation script for you. ### Manual installation 1. Go to `about:support` in Firefox. 2. Application Basics > Profile Directory > Open Directory. 3. Open directory in a terminal. 4. Create a `chrome` directory if it doesn't exist: ```sh mkdir -p chrome cd chrome ``` 5. Clone this repo to a subdirectory: ```sh git clone https://github.com/rafaelmardojai/firefox-gnome-theme.git ``` 6. Create single-line user CSS files if non-existent or empty (at least one line is needed for `sed`): ```sh [[ -s userChrome.css ]] || echo >> userChrome.css ``` 7. Import this theme at the beginning of the CSS files (all `@import`s must come before any existing `@namespace` declarations): ```sh sed -i '1s/^/@import "firefox-gnome-theme\/userChrome.css";\n/' userChrome.css ``` 8. Symlink preferences file: ```sh cd .. # Go back to the profile directory ln -fs chrome/firefox-gnome-theme/configuration/user.js user.js ``` 9. Restart Firefox. 10. Open Firefox customization panel and move the new tab button to headerbar. 11. Be happy with your new gnomish Firefox. ### Required Firefox preferences We provide a **user.js** configuration file in `configuration/user.js` that enable some preferences required by this theme to work. You should already have this file installed if you followed one of the installation methods, but in any case be sure this preferences are enabled under `about:config`: - `toolkit.legacyUserProfileCustomizations.stylesheets` This preference is required to load the custom CSS in Firefox, otherwise the theme wouldn't work. - `svg.context-properties.content.enabled` This preference is required to recolor the icons, otherwise you will get black icons everywhere. > For other non essential preferences checkout `configuration/user.js`. ## Updating 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. ```sh git pull origin master ``` > Note: You can also run the installation script again to update (after cloning again the repo). ## Uninstalling 1. Go to your profile folder. (Go to `about:support` in Firefox > Application Basics > Profile Directory > Open Directory) 2. Remove `chrome` folder. ## Scrollbars To achieve Firefox with overlay scrollbars install [firefox-gnome-scrollbars](https://github.com/rafaelmardojai/firefox-gnome-scrollbars). ## Enabling optional features Optional features can be enabled by creating new `boolean` preferences in `about:config`. 1. Go to the `about:config` page 2. Type the key of the feature you want to enable 3. Set it as a `boolean` and click on the add button 4. Restart Firefox ### Features - **Hide single tab** `gnomeTheme.hideSingleTab` Hide the tab bar when only one tab is open. > **Note:** You should move the new tab button somewhere else for this to work, because by default it is on the tab bar too. See [#54](https://github.com/rafaelmardojai/firefox-gnome-theme/issues/54). - **Spinner** `gnomeTheme.spinner` Use the GNOME spinner for tabs loading. > **Note:** This is optional because Firefox has issues rendering the spinner SVG: > > - **Normal width tabs** `gnomeTheme.normalWidthTabs` Use normal width tabs as default Firefox. - **Bookmarks toolbar under tabs** `gnomeTheme.bookmarksToolbarUnderTabs` Move Bookmarks toolbar under tabs. - **Active tab contrast** `gnomeTheme.activeTabContrast` Add more contrast to the active tab. - **System icons** `gnomeTheme.systemIcons` Use system theme icons instead of Adwaita icons included by theme. > **Note:** This feature has a [known color bug](#icons-color-broken-with-system-icons). - **Symbolic tab icons** `gnomeTheme.symbolicTabIcons` Make all tab icons look kinda like symbolic icons. - **Hide WebRTC indicator** `gnomeTheme.hideWebrtcIndicator` Hide redundant WebRTC indicator since GNOME provides their own privacy icons in the top right. - **Drag window from headerbar buttons** `gnomeTheme.dragWindowHeaderbarButtons` Allow draging the window from headerbar buttons. > **Note:** This feature is BUGGED. It can activate the button with unpleasant behavior. ## Known bugs ### CSD have sharp corners See upstream [bug](https://bugzilla.mozilla.org/show_bug.cgi?id=1408360). #### Wayland fix: 1. Go to the `about:config` page 2. Search for the `layers.acceleration.force-enabled` preference and set it to true. 3. Now restart Firefox, and it should look good! #### X11 fix: 1. Go to the `about:config` page 2. Type `mozilla.widget.use-argb-visuals` 3. Set it as a `boolean` and click on the add button 4. Now restart Firefox, and it should look good! ### Icons color broken with System icons 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. ## Development If you wanna mess around the styles and change something, you might find these things useful. To use the Inspector to debug the UI, open the developer tools (F12) on any page, go to options, check both of those: - Enable browser chrome and add-on debugging toolboxes - Enable remote debugging Now you can close those tools and press Ctrl+Alt+Shift+I to Inspect the browser UI. Also you can inspect any GTK3 application, for example type this into a terminal and it will run Epiphany with the GTK Inspector, so you can check the CSS styles of its elements too. ```sh GTK_DEBUG=interactive epiphany ``` Feel free to use any parts of my code to develop your own themes, I don't force any specific license on your code. ## Credits Developed by **[Rafael Mardojai CM](https://github.com/rafaelmardojai)** and [contributors](https://github.com/rafaelmardojai/firefox-gnome-theme/graphs/contributors).
