Resize Browser Window is an addon that lets you resize and reposition the current window to your desired preference. To work with this addon, open the toolbar popup and click on the desired layout (size & position). Once you click a layout, the window will be positioned and resized to the chosen layout. There are 24 predefined layouts available to choose from in the toolbar popup. If you need a custom layout, please click on the - Add a new item - button at the top-left corner in the popup UI (with a plus icon). A new tab will be open with the custom design layout UI. Simply draw your desired size within the yellow area, then click on the - Save - button to store the custom layout. The new layout will be added to the popup UI. Note 1: items within the toolbar popup UI are draggable and the new order will be auto-saved to the memory. Note 2: this addon only operates on the active screen. If you have multiple screens, please drag your window to the desired screen, and then click on a layout within the toolbar popup to adjust your window. Note 3: to report bugs, please fill the bug report form on the addon's homepage (https://mybrowseraddon.com/window-resizer.html).
