TabBoost - Chrome Tab Enhancement Extension

A Chrome extension designed to improve browser tab efficiency, inspired by Arc Browser.

TabBoost is a Chrome extension that enhances browser tab efficiency. It provides a series of convenient features such as link preview, split-screen browsing, and tab duplication, helping you manage and use Chrome tabs more efficiently, inspired by Arc Browser.

Features

• 🚀 Link Preview: Preview links without leaving the current page. Hold down the Command key (Mac) or Ctrl key (Windows - configurable) and click a link to open it in a popup window on the current page.
• 📺 Split Screen Preview: View two web pages side-by-side within a single tab. Triggered by Shift + Command + Click (Mac) or similar method (Windows) on a link, or activated via the extension menu. Ideal for comparing content or multitasking.
• 🧠 Smart Compatibility Handling: Automatically detects websites that cannot be loaded in preview or split screen (due to X-Frame-Options or CSP restrictions) and provides an option to "Open in New Tab".
• 💾 Web Page Save Confirmation: Intercepts the Command+S (Mac) or Ctrl+S (Windows) save shortcut, displaying a confirmation dialog to prevent accidentally saving the webpage instead of a file. After confirmation, there is a 3-second window to use the native save function.
• ✨ Tab Duplication: Quickly duplicate the current tab using the shortcut (Ctrl+M / MacCtrl+M).
• 🖱️ URL Copy: Copy the current page URL to the clipboard with a single click using the shortcut (Alt+C / Shift+Command+C).
• 🚫 Save Shortcut Override: Intercepts the native Command/Ctrl+S page save, replacing the disruptive dialog with a subtle bottom-right notification.
• 🔒 Enhanced Security: Strict Content Security Policy (CSP) and URL validation mechanisms ensure extension security.
