Firefox saves webpages as .htm instead of .html

more options

Hi.

Firefox saves webpages with extension ".htm" instead of ".html". It is not very important but I prefer to have ".html" extensions, how can I change it?

It may be linked to this extension (https://addons.mozilla.org/en-US/firefox/addon/mozilla-archive-format/) since I installed and uninstalled it recently. I use archlinux.

I found it at last! I was about to surrender, and noticed a file "/etc/mime.types". In that file there is a line "text/html", some tabs, and "htm html shtml". I changed it to "html htm shtml" and now it works.

I think I found the code responsible for that behavior: https://dxr.mozilla.org/mozilla-central/source/toolkit/content/contentAreaUtils.js (line 635).

Am I right? How can I modify that on my computer? (I don't find the file on my computer.)

edit: No, I was wrong.
