How can I fix the problem of a pop up window that appears every time firefix loads titled [Javascript Application] and says "balance.balance is undefined"

The small "[Javascript Application] and balance.balance is undefined" pop up window is followed by a pop up that shows a caution sign and the number 3. They repeatedly pop back up when I click on the OK button or X, I must click them 10 times before they go away. Then Firefox seems to run normally until I exit and try to return later to Firefox.
I uninstalled Firefox and reinstalled it with no effect. I have also run any troubleshooter that seemed to remotely refer to this problem with no effect.
This does not happen when I load Internet Explorer or Google Chrome. Except for this problem, I much prefer Firefox over either one.

hello, can you try to replicate this behaviour when you launch firefox in safe mode once? if not, probably an addon is interfering here...
