thanks for this idea.
The web access appears to be a beta program for skype.
Even though I have used skype via windows for a long time, the web based version says I have to install the plugin for audio and video.
I am guessing I should not install the plugin when I am in windows (I dual boot win 7 and Linux Mint 17.2). Rather I should wait and access skype through FF when I am in Linux.
I just went to skype on the web beta in linux. And there was no plugin message. I guess LM already has the plugin.
