Nice simple alternative to 'Toolbar Buttons' Rated 5 out of 5 stars
Works just great and it's just a mere 13kb.
It was nice to find a simple alternative to Toolbar Buttons / Custom Toolbar Buttons where the site was quite often down and the forum suffered with spam. Always the MaxVersion had to be changed but About Config Button is compatible up to Firefox version 9. No problems here.
I think the Toolbar and Addons Manager icons could be improved and made clearer with a green hammer or spanner image.
There are a number of translation issues that need to be addressed. For example the toolbar icon tooltip needs translating to English in chrome / content / button.xul
