Can you reproduce after disabling gfx.downloadable_fonts.enabled in about:config? If so then all these crashes are related.

Appears to affect www/firefox-esr as well. Unlike gov.uk the crash seems to have different backtrace each time. MOZ_FORCE_DISABLE_E10S=1 doesn't help but we need to collect affected FreeBSD versions to rule out a kernel regression e.g., on -CURRENT.

Comment 2 Emanuel Haupt freebsd_committer

I'm having the same issue (same website). I can confirm that disabling gfx.downloadable_fonts.enabled solves the issue for me.

Comment 3 Tobias C. Berner freebsd_committer

(In reply to Jan Beich from comment #1)
Indeed, toggling this config seems to fix the issue.

Comment 4 Jan Beich freebsd_committer

2020-05-07 19:00:12 UTC

Over to gnome@ per https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues/237

Comment 5 Jan Beich freebsd_committer

2020-05-07 19:01:21 UTC

Err, it's desktop@ after ports r517750.

Created attachment 214242 [details]
workaround: revert regressing backport

I've tried https://gitlab.freedesktop.org/fontconfig/fontconfig/-/merge_requests/94/diffs?commit_id=6edaaa4d1823518a97fb4cc3004d110b1046f742 at first but it doesn't seem to help. Maybe we need to backport more commits.

Comment 7 Jan Beich freebsd_committer

2020-05-07 19:23:30 UTC

Created attachment 214243 [details]
upstream fix

Nevermind, I should've used patch(1) instead of trying to apply the fix manually only to get context wrong.

Created attachment 214244 [details]
upstream fix

Oops, somehow patch header was lost while switching between repos.

Comment 9 lightside 2020-05-08 16:02:56 UTC

Hello.

Also may confirm, that patch in attachment #214244 [details] fixes Firefox's tab crashes for https://www.galaxus.ch site.

Sorry about that, since I proposed to include affected https://cgit.freedesktop.org/fontconfig/commit/?id=61573ad5f7c4dd0860d613d99d0086433240eb75 commit in bug #239167, mentioned in https://bugzilla.mozilla.org/show_bug.cgi?id=1629231#c25 comment.

Thanks Jonathan Kew and Jan Beich for proposed fixes.

(In reply to lightside from comment #9)
Thank you very much for the patch, I will give it a go locally.

Superb – thanks to all concerned for identification of the bug and the rapid fix. 

Fix confirmed, although I found it necessary to _force_ the upgrade:
