1729109 - The preferred default font is no longer used, for some sites, following an upgrade from Firefox 91.0.2

Status: UNCONFIRMED

(Core :: Layout: Text and Fonts, defect)

Description

[Graham Perrin]

Attachment: Firefox 91.0.2,2 on FreeBSD 13.0-RELEASE-P4.png

User Agent: Mozilla/5.0 (X11; FreeBSD amd64; rv:92.0) Gecko/20100101 Firefox/92.0

Steps to reproduce:

1. in Firefox 91.0.2, Default font: Default (DejaVu Serif)

2. in KDE Plasma, prefer Victor Mono for all fonts

3. pages such as https://github.com/freebsd/poudriere/issues/882 appear OK

4. quit Firefox

5. upgrade to Firefox 92.0

Actual results:

6. it appears that DejaVu Serif is no longer used, where expected

7. unexpected use of monospace

– wonder whether this is (in my case) Victor Mono.

Expected results:

6. use of DejaVu Serif

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Layout: Text and Fonts' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Workaround:

• use the desktop environment to set a general font preference
• quit Firefox
• start Firefox.

Using Firefox to change the default font seems to have no effect.

7. unexpected use of monospace

The bug is not monospace-specific.

In this recording:

• a desktop environment preference for general use of Comic Neue
• a Firefox preference for default use of Noto Sans
• Comic Neue is seen at GitHub page https://github.com/mmatuska/zfs-stats/pull/8.

Sites such as bugzilla.mozilla.org seem to be not affected. (Maybe not a good example; it seems that bugzilla.mozilla.org continues to use its own fonts after the user ceases allowing pages to choose their own fonts.)

Not reproducible with more recent Firefox 92.0b9 from https://hg.mozilla.org/releases/mozilla-beta/rev/8139224af521d467e8852b173e5ca5996858c4bd (2021-08-25) on Manjaro Linux.

Setting severity to S4 since this seems to be BSD-specific.
