[Trisquel-users] Belenos: Accessible GUI Calendar app?

[dhunt]

Hi,

I found the Lightning extension from the Mozilla site, and want to add it to  
icedove; how can I do this?  Opening the '.xpi' file with icedove starts an  
empty message.  The xul-ext-lightning package will not install, due to  
Ubuntu's thunderbird being a dependency.  Evolution calendar is not an  
option; the app is inaccessible with orca.

Thanks,

-Dave
