I have used FIREFOX for many years - and have (almost) always been able to use on-line banking successfully. However, since the latest FIREFOX update earlier this week, I have been unable to access my BARCLAYCARD (VISA) account by using FIREFOX. I contacted BARCLAYCARD - and followed their suggestion to try using EDGE. I was able to access my BARCLAYCARD account normally. As I frequently need access to this account I may have no alternative but to discard my use of FIREFOX because of this incompatibility. .
