IE opens url in FireFox

So a weird issue I was having today, I was downgrading my IE to version 6 for some design testing. When I typed in the url for a site and hit enter, the site would open in Fire Fox. After searching through many help sites, I came across the fix.

1. Open your cmd prompt (run>type regedit>enter).
2. Find this entry (HKEY_CLASSES_ROOT\CLSID\ {c90250f3-4d7d-4991-9b69-a5c5bc1c2ae6}).
3. Delete the entry.
4. Close Regedit and you’re done.
