RTMP Downloader not attaching to web browser

[IOM]

Hi,

I've been using RTMP Downloader for a while but recently have had an issue with it not working. It had been working without any problems but about 2-3 months ago it stopped working. I've now discovered that it's saying that it cannot attach to the web browser (Firefox).

I've tried downloading RTMP again, it didn't make a difference. I reinstalled firefox but it hasn't made a difference either? Not sure what the issue is. I looked today and upon opening RTMP Dumphelper it's not even showing Firefox as a supporter browser.

Any help would be great.

Edit: It's finding Firefox again now but still failing to attach to web browser.
