Never use a cursor you don't like again

Custom Cursor Pack changes cursors on web pages opened in the browser. 🙂 Hundreds of cursors manually selected and categorized 📁 Upload your cursor (use 128x128 image) You can change the cursor back to normal by disabling it. Open extension’s popup from the toolbar to do it. Please note: the cursor couldn’t be changed if the mouse is over browser elements e.g. toolbar, search box, or context menus. It works if the mouse pointer is over a page.
