Hi Michael,

Thank you for taking the time to add this report.

However, like Matthias, I was not able to reproduce it using the latest 63.0.1 Firefox Release build (20181030165643) or latest 65.0a1 Nightly build (20181102100039) on Linux or Windows. 

I'm not really sure what you mean by list view. Can you please provide us with some more info on that. I've noticed the Firefox version you are using is 60. Could you provide us with a build ID (from about:support page).

You could also try to update the browser to the latest version, retest and let us know if the issue is still persistent.

Hi Paul,
thank YOU for taking the time trying to help solving my issue!

As you advised, I've downloaded the newest Firefox for Linux (63.0.1), no full install, just unzipped into a directory and ran from there. 

Found out, that using my default profile (migrated for years, even decades now, as far as I remember) I ran into my issue also with the newest Firefox. BUT, good news, if I create a new profile, and use this for testing, the mentioned page is shown CORRECTLY, both with 63.0.1 and my packaged from the OpenSuse team 60.3.0esr. Screenshots appended.

So my issue is related to my Firefox default profile, but I have NO IDEA what I might have done in history to get this error.
Main reason and concern for keeping this old profile are the tons of saved credentials, links/bookmarks and my form etc. history. Using SYNC could help me now, will lose just the form history I guess. 

But of course hints how to "repair" my profile would be highly appreciated :)

Maybe my term "list view" was misleading, I mean the hierarchical list box / list view on the left side, where you can navigate to the different topics. But  looking at the mentioned Android website in correct rendering, I've recognized, that there's also another smaller wrong rendering: No magnifier icon for "search". Appended two additional screenshots, for website https://help.nextcloud.com

I suspect that at some point you have set gfx.downloadable_fonts.enabled to false in your old profile, and this is preventing use of the intended icon font.

Hi Jonathan,

just checked in about:config: 

NO, gfx.downloadable_fonts.enabled is at default (=true), unchanged.

Comment 12

[Jonathan Kew [:jfkthame]]

Hmm, OK. How about browser.display.use_document_fonts? (Default is 1, if it's set to 0 then I'd expect this breakage.)

Or can you check if any other prefs related to fonts are set to non-default values? I thought gfx.downloadable_fonts.enabled seemed likeliest, but there may be others that are relevant as well.

Comment 13

[Michael]

HEUREKA, browser.display.use_document_fonts was set to 0. Set to 1: FIXED !!!

So at first: THANK YOU VERY  MUCH, Jonathan, Paul and others!

Last remark: NO IDEA when/why and this config paramater might have been changed. By me, or by whatever :-) As I said, this profile is very, very old, I'm using Firefox since the very first versions, started when Netscape disappeared. And as far as I remember, I even moved my profiles (Firefox and also Thunderbird) from MSWIN to Linux. Remarkable: First issue like this, in decades :D

There is a check mark in the user interface for this option.
Firefox:options/Font&Colors/Advanced/[x]Allow pages to choose their own fonts, instead of your selections above

Thanks Jonathan for finding the cause !
I will mark this report invalid because this is no bug.
