Description

When accessing the output locally (file:// protocol) with Firefox (v94, Windows), the cookie consent window keeps reappearing on each page.

The setting is stored for each page individually, so if you go to topic A, click Accept, and switch to topic B, you will have to click Accept again. If you then return to topic A, the consent window won't show on that page. But the setting isn't stored globally.

I suggest to never display the cookie consent window at all on local use. I don't think the GDPR stuff applies to content that is on your own hard disk. Also, GA doesn't work anyway when the content is accessed via file protocol.

Expected behaviour

The cookie consent window shouldn't reappear after switching pages, or never appear at all.

Actual behaviour

Cookie consent window keeps reappearing on each page.

Steps to reproduce

1. Enable the cookie consent feature.
2. Open topic A. Cookie window appears.
3. Click "Accept".
4. Switch to topic B. Cookie window appears again.

Thanks for reporting

I agree, as we can't make XHR calls anyway, so there's nothing to be worried about.

I've tried reproducing the issue with Firefox, but I didn't manage to. For me, the consent goes aways after I accepted it. However, showing it during local browsing makes no sense. Fixed in da3540999.

Might be because I have strict mode enabled in Firefox. The strict mode settings don't show up during local browsing, so I thought it doesn't matter. But maybe it does. Anyway, thanks for fixing.

The fix was just released as part of 7.3.6-insiders-3.2.3.
