Update 133.0 Broke Costco logon

[Coisa]

Cannot Log on to Costco.com site after update to 133.0 in Win 10 pro. (

Entering valid account and password cause the logon page to freeze for a minute then returns to log on screen with no messages about failure

Same behavior on two computers.  Log on to Costco via Microsoft Edge works perfectly (on same 2 computers before any trouble shooting).

Same problem. Was auto-updated to Version 133.0    On a Win10 Home system. I enter the login info and the Costco site bounces me back to their sign-in almost instantly, as if I hadn't just tried to sign in!  Disabled Enhanced Tracking Protection, which has worked in the past. No change at all.

Can sign in to Costco with no difficulty thru Chrome browser on the same PC.

Could you both try clearing your cookies for Costco? Here's how:

While on the site, click the lock icon at the left end of the address bar. At the bottom of the drop-down, click Clear cookies and site data...

Firefox should display a dialog for confirmation, go ahead and confirm.

Finally, reload the page bypassing cached files by holding down the Shift key, either:

• Shift+click the Reload button on the toolbar
• Shift+Ctrl+R (or on Mac, Shift+Command+R)

I've had to do this on FedEx, but it might help on other sites, too.

Shift+click the Reload button on the toolbar works one time, then the next time I open Firefox and try to log in it what happened to Coisa continues to happen to me. Edge logs in normally every time.

Microsoft Edge works every time without dismantling security.  Trouble shot costco for hours, taking all security down.  Got it to work but the key for me is costco com logged on Firefox everytime before upgrading to 133.0.  I reported issue to Costco but expect noting for that effort.  Costco has tacking   excess on their website. Here are two screen shots showing my Firefox has Costco as exceptions and two screen shots showing tracking in VPN -
