Sticky Pinned Tab

Sticky Pinned Tab maintains a tab's pinned property when moved between windows. This brings a feature found in Chromium-based browsers (Chrome, Edge, Opera, etc.) to Firefox users.

Motivation

Moving a pinned tab between Firefox windows causes it to be unpinned. On researching possible solutions I found bug 1505014 which won't be fixed. This extension fixes that bug.
