From the moment "upgraded" to Mozilla Firefox 4 in my laptop my Laptop started playing up with my laptop. I this case I am not able to access my bank account - the bank is saying that this is because of Mozilla Firefox 4? I am not able to see my Facebook pages - it says that your Mozilla Firefox 4 is not compatible? My emails are all over the place and I am not able to send it? And every time when I open the pages every time I have to re-enter the user name and password. Thanks in advanced for helping me and giving me your precious time.
