* These buttons are not in the official release, but will be added if they are popular here.


People who used the buttons you picked, also used these buttons.


Normally the buttons would just be added to the "Customise Toolbar" window. But we can also run a script when the extension is first installed to add them into the main toolbar for you. After you can still customise where they placed as before.

Normally extensions get installed into Firefox, but if you intend to install the created extension into Thunderbird etc. check this box and you will be prompted to download the extension instead.

If enabled a suitable number of toolbars will be created to fit your selection of buttons. Then your selection will be added onto these toolbars (unless you have selected to have them added to the main toolbar).

A menu of all the selected buttons can be created and placed in the Tools menu. This feature is experimental and some buttons may fail to work.
