Your wrapper is much appreciated!
I ran into a situation with Iron Portable where URL shortcuts on the desktop and URLs contained in emails (Thunderbird is my email client) always opened in an Iron Portable window without
loading my profile (bookmarks, history etc etc). Using your wrapper in combination with editing the file type "URL: HyperText Transfer Protocol" resolved my problem:
This was how the Open action looked before:
"C:\Program Files\IronPortable\Iron\Iron.exe" -- "%1"
I configured this to my taste:
"C:\Program Files\IronPortable\IronPortable.exe" --enable-user-scripts --disable-popup-blocking "%1"
