On this page: https://help.libreoffice.org/Common/About_Import_and_Export_Filters
there is a mention of Netscape Navigator. I checked LibreOffice preferences and there, it's indicated as Mozilla Firefox. Please update the wiki page accordingly. I have no idea how to do it myself.
Operating System: All
Version: 18.104.22.168.alpha0+ Master
Thanks for your report!
I pushed a patch for review:
It just replaces Netscape in HTML compatibility options, Netscape is also mentioned in the definition of plug-in (https://help.libreoffice.org/Common/Glossary_of_Internet_Terms#Plug-In), but I'm not sure if the description is valid for Firefox...
Stanislav Horacek committed a patch related to this issue.
It has been pushed to "master":
fdo#72340 replace Netscape by Firefox in HTML compatibility options
