BGL360 Denies Access to Pension Page with Firefox

Sadly Firefox has the same problem as Chrome.

Support advice Try CHROME ???

Any ideas as to why this is occurring???

This usually happens to me in Chrome only when I’ve come back from a break (ie the screen has remained dormant for a while or gone to screensaver). If I close all my BGL tabs and log back in, it seems to resolve it.

Have tried that six times. Support have been useless in addressing problem.
