In the customization menu, how do I change the size of the 'flexible space' option?

I want to move the icons about on my toolbar, get some space in between them, but the flexible space option is just too large. I've only just upgraded to the new Firefox. In older versions you were able to change the size of the space. Is that still possible?

That would require some editing of browser.uiCustomization.state. Current Firefox releases come with a flexible space item in the Customize palette because it is used at both sides of the location bar container. Firefox has always supported all three special items (separator, spacer, spring), but there weren't present in the palette. Some extensions like Classic Theme Restorer supported these items.

You can edit the browser.uiCustomization.state pref and change customizableui-special-spring## to customizableui-special-spacer##. Each of these special items need a unique ID (##) to make them work, there can't be two items with the same number.

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

"customizableui-special-separator##" (separator) "customizableui-special-spacer##" (spacer) "customizableui-special-spring##" (spring)
