Portable Firefox and Orbit Downloader

Hello all,

first of all I would like to thank you for this great app (Portable Firefox)!

I've gotten everything to work besides Orbit Downloader. This includes copying the Quicktime dll files etc. etc.

Now the problem:
Whenever I click on a download link, after I installed Orbit Downloader, I don't get the option to download with Orbit. Orbit Downloader doesn't appear in the context menu either.

However, with the regular Firefox, everyting works.

Is there anything I can do to get Orbit Downloader to work with Portable Firefox?

Thanks,
Regve
