About this extension
Window Resizer lets you create custom presets to instantly resize and reposition your Firefox browser window.

Whether you're a designer testing responsive layouts, a multitasker organizing your screen, or just someone who wants windows in the right place every time — this extension has you covered.

💡 Features:
  • Define custom width, height, left, and top values
  • Drag-and-drop to reorder presets
  • Save and edit unlimited configurations
  • Import/export settings for backup or sharing
  • Works with multiple monitors and window arrangements
  • Tab Explosion: Instantly split all tabs from your current window into a visually organized layout of separate windows. Layouts are optimized for 2, 3, 4, or 5 tabs, making multitasking and comparison effortless.
  • Gather Tabs: Quickly gather all tabs from all open windows back into a single window, automatically applying your favorite preset for size and position.

Stay organized. Stay productive. Resize smarter.
