Workspaces for Firefox од Nathan Moos

Workspaces for Firefox, inspired by those in Linux desktop environments.

Press Alt+Space (Ctrl+Space on Windows) to show the Palette, which allows you to search for tabs, regardless of which window or workspace they are present in. Press Enter (or click) to switch to the selected tab, and press Shift+Enter (or click the Paste icon) to "teleport" the tab into the current window, which transfers it with no loss of state.
