Форум поддержки Firefox

I am getting to the end of my tether with Firefox. I have used it for years but the increasing issues are driving me to distraction.

It will not display comments on the Daily Mail UK website, The Telegraph UK site and the screen is scrambled if I try to use Ebay Philippines. I am not a computer expert but I have tried to follow other peoples suggestions with no luck.

I cant see the point of persisting with FireFox unless these issues are rectified.

Any suggestions would be very welcome.
