Hello, I really like using the "Shortcuts" (Top Sites) feature on the Firefox new tab page. However, there is one problem: Firefox automatically adds new shortcuts from recently visited sites. I would like to keep only the shortcuts I manually pinned, without Firefox suggesting or adding new ones automatically. Currently, if I disable browser.newtabpage.activity-stream.feeds.topsites, all shortcuts disappear, and if I leave it enabled, Firefox keeps adding unwanted sites. Could you please add an option to disable automatic shortcut suggestions while keeping only pinned shortcuts? This would make the feature much more convenient for users who prefer to manage their shortcuts manually. Thank you!
