Firefox not allowing user to checkout

using version 1.5.6.c

Using Firefox
Customer can add an item to cart
Then clicks checkout and it takes him to login page. Logging in takes him to cart page and the cycle loops forever

On Chrome, you log in and go to cart and proceed to checkout where you can choose payment method and discount code addition, etc.

With Firefox you can check out but only by clicking "Checkout with Paypal" button.

Any idea what is the problem?

Tested with firefox and I can select either paypal or check/mo from the payment page and get to the confirm page, when choosing Paypal I get sent to Paypal and can cancel and get sent back to site. So as far as I can tell it works fine.

Make a test purchase


then click "checkout" takes me to https://www.ultimatepicklejar.com/ze...ain_page=login

Entering email and password then clicking Signin takes me to https://www.ultimatepicklejar.com/ze...=shopping_cart

Here clicking on "Checkout" should take a user to https://www.ultimatepicklejar.com/ze...ckout_shipping but does not on firefox for me! This is where it loops.
On Chrome it works like fluid.

At one time I did a suggestion and addressed a possible OCSP cause and got Firefox to work again but it is not responding right now. The fix was temporary it stated.

Maybe it is reboot time. I will and return here

rebooted, re-installed Firefox and still same result!
I do not have a clue!
Works good in Edge on my comp also... Just firefox.
I have 2 customers not able to make sales either. One claims not being able to find shopping cart and the other not being able to go to checkout.

UPDATE: I opened Firefox private window and it works great! Now to find what on regular window is causing problem. Hopefuly I can advise customers to change browsers or use private page for check out.............

It was a cache issue! I cleared it and it works correctly!
Mr Moderator. If you could , remove my inks but leave the subject matter for someone else having the problem. I have customers to attend to as well and maybe can help them IF my cure works again later

I had something similar immediately post-upgrade:
Firefox F12 Developer Tools->Storage->Cookies->delete zenid.
It gets re-created and all is well subsequently.
