Besser Pinned Tabs sγur Gérard Kieffer

Firefox only features (to be added in Chrome)

• When you click ANY link in a pinned tab, opens it in a new tab instead of replacing your pinned page.
  (Except for same-URL links, to prevent a tab being duplicated when refreshing a page)

Chrome and Firefox features

• If you type a new address in a pinned tab's address bar, opens it as a new tab to preserve your pinned page

Chrome-only features (Firefox already handles this behaviour natively)

• Automatically reopens pinned tabs if they're accidentally closed, whether using keyboard shortcuts or mouse clicks.
• When you click a link to a different website in a pinned tab, opens it in a new tab instead of replacing your pinned page.
