How to use You can use keyboard shortcuts, context menus, or the toolbar button of Format Link extension to copy a link in the specified format. Before doing that, you can optionally select some text which may or may not contain a link.
- keyboard shortcut The keyboard shortcut for "Copy a link in the default format" is shortcut for clicking the toolbar button. The link is copied in the default format and the popup is shown under the toolbar button. Also there are shortcuts for copying in the link in the corresponding format regardless of the default format. See Manage extension shortcuts in Firefox | Firefox Help for showing and changing keyboard shortcuts.
- context menu Open the context menu and select the "Format Link as XXX" menu item. "XXX" in the menu item label changes as you change the default format by clicking the "Set as default" button in the popup page for the toolbar button. If you check the "Create submenus" in the options page and save the options, submenus for each format are created under the "Format Link" context menu group.
- toolbar button When you press the toolbar button of "Format Link", the link is copied in the default format, the popup page becomes open, and the formatted text is shown in the text area. If you want to copy the link in different format, you can press one of the radio buttons. Also if you want to change the default format, you can press the "Set as default" button.
Flexible settings You can modify formats in [Tools] -> [Extensions] -> Clik "Options" link in "Format Link" Extension. In format settings, you can use the mini template language.
