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,

I have always been able to use Firefox to login and place grocery order on the Kroger website. This afternoon the server will not let me in, saying access is denied. I was able to login from Microsoft Edge. Is the Kroger website blocking Firefox logins? I have been having trouble loading the website for the past month or so, but have always been able to get in. Does anyone have a fix for this problem? I rebooted my computer to make sure it was not my PC.

Since the update I performed today, 4/27/26, I am unable to upload files to my NAS via the Firefox web browser on a Windows 11 PC. I can still do it via the Google Chrome browser so I am not completely crippled, but it would be nice if I could still use Firefox for this work. Any suggestions on how to fix this, or will it require the software itself to be fixed?

VPN has appeared at the top of the screen with an option to click the GET STARTED button to try the built in option. I haven't done so but now can't access a website I regularly use. Their tech team tell me that the VPN is blocking access. How do I disable this when I haven't asked for it so don't know where to find it
