How can I add my custom button to the Safari toolbar?

Question

I want to add my custom button to the Safari toolbar.

Please let me know how this can be achieved.

Answer 1

See Best way to write a Safari Extension on Stack Overflow.

Answer 2

This blog post could be of some help, it shows how to add a custom home button to the safari toolbar.

Apparently you just need to replace a PDF in a resources directory, with the PDF containing your icon design.

Apologies if this is unrelated to the question.
