TabGroups Manager


TabGroups Manager helps to classify and organize tabs by dividing them into Groups. Because tabs become easier to manage, you can never have too many! TabGroups Manager is ideal for tab power users.

*GroupBar + Groups:

TabGroups Manager adds a GroupBar which is displayed above the tab bar. Here you can create Groups for organizing and managing your tabs


This feature allows you to temporarily put a group into hibernation (sleep mode). This is useful if you have too many tabs open and need to save memory.

*Restoring Sessions:

The standard Session Store feature of Firefox is necessary to restore Tabs, Groups and Hibernated Groups when re-starting Firefox.

The developer does his best to document every feature added to TabGroups Manager. Furthermore, all questions and bug reports are always read and responded to.

However, it is important to note that the developer writes (and reads) in his native language (Japanese). Translations are done by machine and so may not be perfect. This language barrier cannot be helped.
