Visual List Comparator автор JBO

Visual List Comparator helps you see differences between two lists without leaving the page. Click Launch from the toolbar, pick a source list and a target list with your mouse, then compare. The add-on shows both lists side by side and highlights matches, items only in the left list, and items only in the right list. It works with common patterns like bullet lists and tables and it can dedupe repeated rows so the results stay clean. You can switch case sensitivity on or off and trim stray whitespace so small formatting changes do not overwhelm the view. Everything runs locally in your browser and nothing leaves your device.

Use it to compare product tables, pricing charts, article versions, documentation indexes, or any page section where items are laid out in a list or table. The goal is to make differences obvious at a glance so you can decide quickly.
