I've been using NoScript for a really long time and I never had any issues (except for the first few weeks of the "Firefox Quantum" update)

The new UI is really bad. I'm always open for new UI designs but this isn't good. Especially dark mode is horrible. I had to change it to light theme since it's a little bit better to read.

If it's possible offer a classic theme as an option or redo the new theme.

Update: Thanks for the answer! The dark theme still isn't perfect but at least I can switch to the classic style!
