Tab Manager for Mobile by utubo

This is an add-on for Android.
You can install this on Windows tablets, but I have not tested it on Windows or other operating systems.

This does not work well, now.

This addon show tabs list, and you can swipe a tab to close.
It open Tab-manager page, when click this addon's icon (in address bar).
You can bookmark Tab-manager page.

But...
Firefox broke the Api about tabs in version 58.

Currently, Firefox does not provide information about suspended tabs to add-ons (including tab order information).

WebExtentions of Firefox for Android 58 can't these.

• Control suspended tabs
• History
• Restore session
• Bookmark
• Top site
• Dupe 'about:*'
• Show favicon
• Restore session
