Not sure what happened, but starting last night for no apparent reason, I can't get thunderbird to launch firefox anymore when a link is clicked. i've reloaded thunderbird (the version from this site) and it has not helped ... any ideas?
[i do have launchy installed; i just installed thunderbrowser to see if that helped ... it works, but i still can't get a link to open in firefox portable from it ... firefox IS the default browser as far as I'm aware, unless that can be 'overridden' somewhere]
