Several of my utility companies and bank sites do this still. It’s absurd and in the stranger places.

What pisses me off is seeing more and more “You need to upgrade your browser for this site!” when using Firefox.

Having to use a spoof header gets frustrating frequently too.

If you are decent with script type stuff, and have tasker, I believe you can build your own via kwgt:

You can use tasker to set up variables that kwgt then can render in several ways.

I’ve only done simpler things but it’s worked well for me for years.
