Workspaces+ by jahangir1x

Organize tabs into workspaces in Firefox.
(This extension development was inspired by Tab Workspaces made by @fonse.)

Features (from Tab Workspaces)

• Each tab belongs to a workspace. New tabs are automatically added to the current workspace.
• Switch between workspaces from the toolbar icon to keep your tabs organized.
• Tabs in other workspaces are safely hidden away.
• Pinned tabs are visible from all workspaces.
• If you have multiple windows open, each one has its own set of workspaces.
• Send a specific tab to another workspace from the right-click menu.
• Press Ctrl+E to open the list of workspaces, then press 1-9 to switch between using keyboard shortcuts.
• Search through your tabs in the address bar. Type "ws [text]" to begin searching. Choose a result to switch to that tab.

Extra Features

• Clone workspace.
• Current workspace indicator.
• Dark theme.
• Consistent and non-closing UI.
