I'm not sure if anyone else will find this useful but I made a #cashu browser extension which is just a simple iframe that opens http://cashu.me. This is my preferred way to use what I consider to be the best Cashu Wallet in the browser.

Links Below 👇

Chrome/Edge/Opera/Brave/Vivaldi:

Firefox/Zen:
https://addons.mozilla.org/en-US/firefox/addon/cashu-me/?utm_source=addons.mozilla.org&utm_medium=referral&utm_content=search

I'll make it a priority to tidy up my long-standing branch for http://cashu.me and submit a PR that could unlock a lot of features if it gets some downloads.

Obviously if you have issues with it let me know, there shouldn't be any because its super simple.
