Firefox-Hilfeforum

Hello everyone,

Why some Wikipedia pages cannot activate reading mode under Debian 12 and Firefox ESR 115.9.1, for example this English Wikipedia page on Emmabuntüs does not allow reading mode to be activated while French, Spanish and German pages can ?

See our test video on this subject: http://share.emmabuntus.org/Accessibility/Firefox_mode_lecture_non_disponible_emmabuntus_en.mp4

Is there a utility to test pages compatible with reading mode?

Or otherwise in which Firefox log file to see if a page is compatible or not?

Thanks in advance for your help.

Please see the attached image.

Firefox believes I have a security key.

What is a security key? Where do I find it? Why does Firefox think I have one?

And why is there no helpful information to explain this confusing UX?
