Bug#962177: epiphany-browser: Does not recognize djview-plugin

[Janusz S. Bień]

Package: epiphany-browser
Version: 3.32.1.2-3~deb10u1
Severity: normal

According to Léon Bottou it should do and really does on Ubuntu 18.04:

https://sourceforge.net/p/djvu/bugs/319/#c805/b347

Although djview-plugin is installed, about:plugins shows nothing and the
DjVu documents are downloaded, not opened.

When I start epiphany browser, I get

--------------------------------------------------------------------------------
sbien at debian:~$

Can it be relevant?
