I know firefox is supposed to be safer by not autoexecuting many things but it becomes a nuisance when everywhere I go I can't play something because I don't have the proper plugin. Now this wouldn't be so bad if it would just give me the option of installing it but usually just says no plugin available.
For example if I go to xmradio.com and try to play music from my account it just gives plugin required and none available. Same for live36. Seems like for having more security there is a price in functionality.
