The plugins worried me a lot since the Netscape went down , There must be strong pressure from the Mozilla community to ensure flash, realplayer, acrobat, java, *.* plugins are developed for Mozilla.
If companies start to produce only plugins for IE, Mozilla will suffer a very, very strong blow. So will all other browsers that use NS based plugins.
Plugins are a part of online life, even though I hate sites with plugins they are here to stay, and Mozilla mustn't be shut out of the plugin party.
