firefox toolbar issues

I use Proxybutton extension for switching proxies heavily. I drag the proxybutton to the toolbar. But everytime the browser restarts the toolbar state vanishes away.

i searched firefox bugs and found this:

Bug 341696 – Tool bar customization is not maintained after closing and re-starting the browser. (edit)

which pointed me to this article.

im gonno try this now.
