For some easy usability, I have enabled a plugin white list in my firefox 31, and the list is here : http://bbs.kafan.cn/thread-1757700-1-1.html,
which mainly contains popular Bank and Society plugins in China. The white list will make the users more easily use some web service. ( And I also don't like making all the plugins enabled by default )
But I don't know what popular plugins people in other countries use, so you can send the plugin file name and function to me if you want me to expand the list.
Tete also can refer to the list. :)
ps: May we send the list to Mozilla bugzilla or must need plugin author to submit it?
