This is the first public WebExtension rewritten version of FireTitle.

This version allows to prepend the windows' title with
- a window's customized name
- the browser's version and buildinfo
- the number of tabs
- custom text
- custom separator

This version does not allow, due to restrictions on WebExtension API
- to move or remove the document's title from the title bar
- to move or remove the browser's name from the title bar
- to change de separator between the document's title and the browser's name in the title bar

See extension's properties to customize that and get more documentation.
