Thank your for your input. My tune menu does not have the [Reset permissions] button. I had to click the “Site settings” link…
, which took me into settings for that site, hrblock.com. From their I clicked the [Reset permissions] button…
Further down on that settings page, I confirmed that JavaScript was enabled…
After reloading the page, it did not work.
Then after clearing all my cache and rebooting, it did not work.
I found a different “login” link on their website, which does work for me…
Frustrating, but at least I have a work around.
