Access Denied and 403 Responses

more options

When navigating within retailer web sites, some clicks, such as searching for their nearest branch, consistently produce an Access Denied message, such as the following one:

Access Denied You don't have permission to access "http://www.argos.co.uk/stores/?" on this server.

Reference #18.d639dd58.1652362340.afeb7586

I get a similar response when trying to open some web sites, such as Sainsburys.co.uk which has just responded with the following 403 message:

403 ERROR The request could not be satisfied. Request blocked. We can't connect to the server for this app or website at this time. There might be too much traffic or a configuration error. Try again later, or contact the app or website owner. If you provide content to customers through CloudFront, you can find steps to troubleshoot and help prevent this error by reviewing the CloudFront documentation.

Are such searches controlled via Firefox? If so, do I need to change a Firefox setting to overcome the problem?

Thanks for your prompt response. Changing the Privacy & Security setting back to Standard has solved the problem with the Sainsburys site, but on the Argos site I am still getting the access denied response when I click on their "Stores" button. I tried removing the block on tracking but that didn't help so I switched it on again. Any other suggestions?
