Stylo bởi Arvanta

Stylo gives Firefox users a focused way to customize the appearance of the web without editing website source files.

Create custom CSS styles and apply them only where they are needed. Target a specific domain, a URL prefix, or a regular expression. You can also create Global CSS rules for changes that should apply across websites.

Features

• Apply custom CSS to individual domains.
• Target pages using domain matching, URL prefixes, or regular expressions.
• Create Global CSS for broad visual changes.
• Enable or disable Stylo globally from the popup.
• Enable or disable individual styles instantly.
• Add a new style for the currently active website from the popup.
• Preview changes without manually reloading the page.
• Keep styles separated by their URL targets to reduce unwanted interference.
• Search and manage domains from the dedicated management panel.
• Choose Light, Dark, or Auto theme modes.
• Import and export complete JSON backups for migration or safekeeping.
• Use a custom confirmation dialog before deleting styles.
