[Working] flashgot media button not appearing

[zetrotrack000]

Hi
I am a linux user and using flashgot extension in firefox for many years with extreme satisfaction. My default download manager for flashgot is 'axel'. Few days back, I have upgraded my distro from linux mint 14 to linux mint 15. Then I have installed flashgot extension and put its 'flashgot media' button on toolbar as usually I used to do. But this time, when I play any flash video, the flashgot media button is not appearing on the toolbar (which was used to be appeared in my previous distros). How can I fix it?
PS: When I put the flashgot media button on the toolbar, I noticed that the button has no icon, while I was customizing the toolbar and selecting and dragging the flashgot media button onthe toolbar.
I have tried it on YouTube, DailyMotion, Vimeo and IMDB.
Regards

Some URLs where it is not working?

I ran "apt-get dist-upgrade" and the problem is fixed by its own. Strange but good
