Firefox old-style refresh-stop and new tab buttons

I like to have separate Refresh/Stop and New Tab buttons in Firefox. I also use Tree-style Tabs. Here’s how to do it:

[Edit – note from May 1 2014 in context of FF29 – how to split refresh as a movable button again –]

1) Open the customise toolbars dialog:

Firefox customise buttons

2) Look to the far right of your existing toolbars to see if you can find the two icons to drag over to new positions. The desired end result looks like:

New Tab and Refresh Buttons

Note – the New Tab button may look different in the customise toolbars dialog e.g. a green plus, but it displays as depicted – at least in current versions of Firefox (25 at present and counting ;-)).
