I would like to set up Skype on my Thunderbird software. However I do not see any way to add Skype. This would be really useful and interesting, particularly for professional purposes. I know it is possible to use third programs or websites to access skype (like imo.im) so I assume there is a way doing it on thunderbird.
Please note that I already contacted Skype Support, and they forwarded me to Thunderbird Support (if necessary, I can provide the logs here). Furthermore I tried to contact thunderbird support but I didn't received answers, explaining why I am asking here.
Thank you all in advance for your help.
