Webuser Forums: Firefox issues please help me

Hi All...

I have just switched from IE7 to Firefox...
I have some issues, certain videos do not play on certain sites, for instance i will go on youtube and the videos will play, i will go on the bbc and www.lcfc.co.uk and the sound will play with no videos.

I have searched everywhere but i cant get anything....
I have also noticed that Firefox seems to ask me to remember my password for a site but then when i select yes on the sites i want to remember they seem not to remember them.

Sorry if this makes no sense!!

I hope somebody could talk me through the exact plug ins i need.... i have flash, java,windows media player, real player, quick time installed... But no Joy!!

Thanks guys.

P.S - Do i switch back to IE7... Mozilla is faster but so many flaws!!
