This extension leaks memory badly on notebook.google.com. I measured ~1.5 GB of JS heap retained per NotebookLM tab, attributed entirely to this extension's content script realm, even after normal use. With two NotebookLM tabs open it added roughly 3 GB to my browser's memory footprint. Great concept, but needs a memory audit before I can keep using it.
