Are there any non-JavaScript web wallets?
AFAIK no, you hardly can find website without JavaScript these days.
From list at
https://bitcoin.org/en/wallets/web/, i tried create account/wallet without JS (with No Script help), here are the result :
1.
https://www.bitgo.com/ : Button "Signup" and "Login" gone
2.
https://wallet.btc.com : Stuck at loading screen (Only showing loading animation with colorful triple dot)
3.
https://coin.space/ : Stuck at loading screen (Only showing logo with text "Coin")
