[JAWS-Users] Thunderbird 38.1.0

[anna vimini]

In this new release of Thunderbird now every time when I first open the 
program a dialogue comes up that says Thunderbird  now has calendar 
functionality by integrating lightning extension
does anyone on the list know how I can keep this dialogue from showing up?
I am using windows 8.1 jaws 15 and Thunderbird 38.1.0
thanks in advance
