Roundcube all gibberish

[Terrorelfe]

Yesterday everything was good, today everything, login, e-mails, is displayed illegibly.

If I copy and paste the illegible text, it will be displayed correctly.

What is the problem?

What can I do?

Edit: I've now tried it with Chrome instead of Firefox, it looks good.

Still the question, what can I do to make it work (again) anywhere and with any browser?

Roundcube is open source software it is not a service. If you are not responsible for managing your installation of Roundcube then contact who ever is - your email provider.

Tell me something new.

Anyway, maybe the problem will be solved with the next Firefox update.
