Are you feeling like your Firefox browser could use a makeover? Whether you’re still using an older version or just prefer a different aesthetic, Firefox Review is an exciting option that reimagines the look of Firefox by matching the design language of Firefox Preview. In this blog, we’ll walk you through how to install and customize this stylish theme!
Understanding Firefox Review
Firefox Review was a CSS-based revamp for the classic Firefox interface. With the advent of v1.1, users can choose between light and dark themes, enhancing visual appeal tailored to any user’s mood. The layout and interactions have seen substantial upgrades in v1.1.4, leading to improved menus and user experience.
Installation Process: Let’s Transform Firefox!
1. Extraction
Begin the journey by extracting files from the zip folder. Here’s how:
- Open your downloaded zip file.
- Extract userChrome.css, userContent.css, and userColors.css into your chrome folder.
- Unsure where this folder is? Follow these steps:
- Open Firefox.
- Enter about:support in the URL bar.
- Look for the Profile Folder under Application Basics.
- Click ‘Open Folder’ and voilà, you’re in the right place!
- It should look like this: C:\Users\username\AppData\Roaming\Mozilla\Firefox\Profiles\profile-id\chrome
- If the chrome folder doesn’t exist, don’t worry! Just create a new one and drop those files in.
2. Enabling CSS Alterations
With the files in place, we now need to enable CSS alterations in Firefox:
- Open Firefox again.
- Type about:config in the URL bar and hit Enter.
- Accept the risk warning.
- Search for toolkit.legacyUserProfileCustomizations.stylesheets.
- Enable it by toggling the setting.
- Close and reopen Firefox.
And just like that, your Firefox Review should be good to go!
Switching Themes Made Easy
Once installed, you can switch between the themes effortlessly!
- Navigate to the Customizations Menu.
- Select either Light, Dark, or Default.
- By choosing Default, Firefox Review will follow your Windows OS theme automatically.
If you’re feeling creative and want to customize the color scheme further, just dive into the userColors.css file and edit the colors to your heart’s desire!
Troubleshooting Your Setup
If things don’t go as planned, don’t worry! Here are some troubleshooting tips:
- Double-check that you have placed the CSS files into the correct chrome folder.
- Verify that you enabled the CSS alterations in the “about:config” settings.
- If Firefox Review doesn’t appear as expected, try restarting your computer.
