Update your browser. I recently got stuck in that with a slightly old version of Firefox. After updating, everything worked again.

I suspect it wasn't cached state or plugins, because I tried to clear those to no avail. My bank then informed me it didn't like my Firefox version (despite being relatively recent).

I have the most recent version (116.0.3) and I'm also seeing a loop. This includes trying the site without plugins.
