Firefox hangs on page loading

[T0b1-iOS]

Hello,

it seems that Firefox is unable to correctly load the webinterface and instead just hangs with seemingly random status messages in the bottom-left corner.
Quick debugging showed that the issue is caused by this line in setTheme.js
document.querySelector( 'link[href*="toggle-bootstrap-dark-overlay.min.css"]' ).disabled = false;
more specifically, the .disabled = false; part.

Chrome & Safari work fine.
Since I'm not overly familiar with the dark magic you seem to be doing regarding the dark-theme.min.css I wanted to ask if this is a bug in your code, in Firefox or if I just didn't properly set up the serverside part of the webinterface which is probably more likely.

Regards

Thanks, that fixes the issue!
You just need to also apply it in login.php and register.php
