Rename Tab Title of Domain/URL от Prashant Kamdar

With this Firefox extension, you are able to change the title of all pages of a site in one go, or each individually (if you so desire).

• If both tab & domain are set, "Tab title" is given higher preference over "Domain title"
• You can delete any title which is set using the "Delete" button next to it
• If "Tab title" is deleted, the "Domain title" will be honored (if it is set)
• Once a title is deleted (tab or domain), please reload the page for changes to reflect
• By default, in the textboxes, the current title is populated
