With cookies disabled chewy.com is a white page but

However https://www.chewy.com/app/content/about is fine

so not a Firefox issue but a chewy one

Not so. " https://www.chewy.com/app/content/about " takes me to the sign-in page, but when I try to sign in I get the white page. Again, everything works with Safari, but not with Firefox, so it's a Firefox issue. Started with the most recent "upgrade."

Have you tried clearing cookie memory/data for chewy, then login from scratch etc. So it's not that you can't access as in the title, but you can't sign in, a different issue.

Well I don't have an account so won't test that.

Still I would say the sign in page is looking at your cookies and they are under or over baked. Clear and start afresh would be the first thing I would do

next would be to see if I can read the source code, is anything there, if not it seems to be a security issue and again the cookies would be my first enquiry.

Have you searched the internet . . . . ???????

Seems a common occurrence and not specific to Firefox

Yes, I cleared the cookies, which I regret. Didn't help. On the Internet, I see I'm not the only Firefox customer with this issue. I get e-mails from Chewy, offers and such. I can open them, but when I try to respond, I get the white page. Also, when I try to simply go to the site on my own, I get the white page.

" Also, when I try to simply go to the site on my own, I get the white page."

You mean when you try to sign it, otherwise it's fine ???

Did you see this?

"Chewy website is showing a blank white screen on Google Chrome. I can access it on Explorer, on my phone, everywhere else but on Google Chrome on my laptop. I have deleted cache, reset permissions blah blah blah, still won't work. I had no issues until I had to reinstall Google Chrome on my laptop. Every other site works"

So more than an Fx issue

No, I mean I can open their e-mail, but I can't respond to it or click on anything.

So it also affects Chrome. I don't use that. I can use Safari, everything works fine there, but it's inconvenient. Either way, the common denominator seems to be Firefox. BTW, I got one message telling me to contact Chewy, which I did (by phone). They have no idea...
