MultiButton 作成者: gchristnsn

Allows opening multiple links at once with one click. Suits for people who do not use the bookmark toolbar. The add-on settings and all listed URLs are available from the toolbar button context menu.

It is possible to set a time threshold for each link in the format: >15:00 or <15:00. The link will be opened only if the current time is greater or less of the time specified.
