after updating to new version of Firefox, I can no longer access certain websites

received an email from a website, Chewy.com, about upcoming order. I clicked on Chewy's manage order button that should have taken me to their website so I can make any changes. What it did was tried to open up their website in a new tab, but the tab was blank. I refreshed the website and got nothing but a blank website page. I cleared my cache and tried to load the page again but still received nothing. This is not the only website this is happening to but others like Walgreens, AT&T,

There are some tips to try:

Basically clicking around their site first might help open the login page later. No idea what they do with their security though — they seem to trigger on so many things…

Oh! Actually, I do see something suspicious in your browser data — it identifies itself as "Config/91.2.2399.16" which is total nonsense. See https://support.mozilla.org/en-US/questions/1581078#answer-1817518 — it might be something like CCleaner's Kamo addon messing up with their security, and that's why they don't allow you in: https://support.mozilla.org/en-US/questions/1580836
