When trying to access my 'Activity' page on my Royal Bank account, Firefox signs me out. I have tried clearing, cache, cookies etc with no luck. I have also tried using my Surface Pro & Firefox & it does the same thing. Have also tried using Microsoft EDGE on both computers & the account information under 'Activity' is displayed correctly. Turned off all plugins with the same result. Had to leave JavaScript running as site uses it. Also contacted RBC & they checked with there tech dept & no one else has reported any problems like this. Any suggestions as to what to try next?
