Rated 4 out of 5 stars
Works great with Thunderbird/Icedove 10. Finally I can choose with which browser I open a link from an email. Great! This is a reason to switch from Kmail to Thunderbird! I give only 4 stars because the application auto-detection doesn't work with Linux (you have to manually create a launchy.xml) and because the Launcy entries are not directly in the context menu of the link but in a seperate "Launchy" submenu.
