If you are comfortable with running a Python script (Python is available on both Linux and windows), then I would suggest using the Kijiji-Repost-Headless project.

This is what I use now to repost my Kijiji ads, and it is being actively developed. Unfortunately it is not quite as simple to use as clicking a button in your browser, but it does work. Perhaps someday it could be developed into a real browser extension to make it easier to use.
