@gmc Here's the suggested reply we were given. Hope it helps:
"Thanks for letting us know! LibreWolf's strict privacy settings (particularly its localStorage restrictions) can interfere with how the quiz tracks progress between questions. The easiest workaround for now is to allow localStorage for this site in your LibreWolf settings, or try a standard Firefox or Chromium-based browser. We'll look into making the quiz more resilient to these restrictions β appreciate the report!"
@gmc We've found a way to bypass the need to change your browser settings, which might be preferable. Here's the lowdown:
"The effect: if LibreWolf (or any other privacy-focused browser) blocks localStorage access, the quiz now silently falls back to sensible defaults instead of crashing. User preferences just won't persist between sessions in that case, which is a perfectly graceful degradation β the quiz itself will work fine."
We hope either of these solutions works for you π€ @timhopper
