Tab Count in Window Title sɣur Lej77

Show the tab count for each window by adding a prefix to the window's title. The formatting of the tab count is customizable.

This extension also adds a toolbar button that opens a popup. The popup can be used to name windows and these names are then shown in the window titles.

This extension allows for some extra customization options when using "userChrome.css" since the title prefix is available as a CSS attribute. You can for example make some CSS code apply only when you have one tab open. The attribute can be accessed with:

#main-window[titlepreface^="[1] "]


This extension was initially developed to allow for such customization in order to hide Tree Style Tab's sidebar when a window had only a single tab (GitHub issue, Tree Style Tab Wiki entry with CSS).

Permissions:
"sessions": needed to save window specific data such as window names. This is an optional permission in the latest version.
