Global Pinned Tabs in New Windows — vFoundry, LLC

Save selected tabs so they automatically open pinned in every new Firefox window, with full support for Multi-Account Containers.

What this extension does

This add-on lets you treat some tabs as "global" pinned tabs. When you right-click a tab and choose "Pin in new windows", its URL and container (including Multi-Account Containers) are remembered. Each time you open a new normal Firefox window, the extension recreates those saved tabs as pinned tabs in the same containers. You can manage the list at any time from the options page.

Features

• Context Menu Integration – Right-click any tab to "Pin in new windows" or "Unpin from new windows".
• Multi-Account Container Support – Tabs are pinned per URL + container combination using the tab's cookieStoreId.
• Automatic Tab Opening – New normal browser windows automatically open your saved entries as pinned tabs.
• Options Page – A dedicated settings page lets you review, add, and remove globally pinned tabs.
• Per-Container Control – The same URL can be pinned in different containers independently if you choose.

Data and privacy

This extension stores only a small list of URLs and their associated container IDs (cookieStoreId) in Firefox's local extension storage. The data never leaves your browser unless you choose to sync or back it up yourself.
