How Do They Know?

How do, ASDA for example, know what browser is being used? They say they no longer support Internet Explorer 11, so how would they know that another browser was being used or not? Ta Muchly and Take Care All!

Woodelf the announcement is not for you personally, its a general announcement to let customers know that they are not supporting Explorer 11.

This should help.

I can program my Humax PVR via the internet but not with Firefox. After getting strange behaviour using Firefox I tried with Google Chrome and it worked perfectly. ASDA probably make the announcement for people who are having problems to encourage them to try a different browser.

Every website you visit sees information about your browser and IP address.

there are many ways but I imagine they scan the process list.

Websites know when you use an ad-blocker, too.

Woodelf are you sure you are using Edge and not Explorer?

You'd be surprised how much info is passed on you when a connection is made.
