Pin Bookmark от Xyborg

Adds “Open as pinned tab” to the bookmark context menu.
Open a single bookmark or an entire folder as pinned tabs.
“about:” pages (e.g. about:config, about:addons) and local files (file://) cannot be pinned automatically due to Firefox security restrictions. In these cases, please pin manually.

Features:

• Open single bookmarks or entire folders
• Choose whether tabs open in background or switch immediately
• Available in English, German and Spanish

No data collection. No external requests. Everything runs locally.

Tested with Firefox 140 ESR and 148.
