Package: firefox Version: 49.0-5 Severity: normal Since the move to GTK3 in 49.0-5, the fonts and widgets on my hi-dpi (3840x2160, 240dpi) display are tiny. The actual rendered content is sized as it was with GTK2.
This is the case even when run in --safe-mode; the dialog asking to confirm running in safe-mode has small fonts and buttons. Setting GDK_SCALE=2 improves the situation, but my understanding is that this is supposed to happen automatically. This seems to be a gtk3 thing, as installing gtk-3-examples and running gtk3-demo shows the same problem. So I doubt there's a particular bug to fix on the _firefox_ side, but it is a potential data point against enabling gtk3 (i.e., from my perspective it's a regression in firefox). -- Package-specific info: -- Extensions information Name: BugMeNot Plugin Location: ${PROFILE_EXTENSIONS}/{987311C6-B504-4aa2-90BF-60CC49808D42}.xpi Status: enabled Name: Dactyl Binary Utils Location: ${PROFILE_EXTENSIONS}/binary Status: user-disabled Name: Default theme Location: /usr/lib/firefox/browser/extensions/{972ce4c6-7e08-4474-a285-3208198ce6fd}.xpi Package: firefox Status: enabled Name: Google Redirects Fixer Location: ${PROFILE_EXTENSIONS}/jid1-zurvdcat3xo...@jetpack.xpi Status: enabled Name: HTTPS Everywhere Location: ${PROFILE_EXTENSIONS}/https-everywh...@eff.org.xpi Status: enabled Name: Multi-process staged rollout Location: ${PROFILE_EXTENSIONS}/e10sroll...@mozilla.org.xpi Status: enabled Name: PassFF Location: ${PROFILE_EXTENSIONS}/pas...@invicem.pro.xpi Status: enabled Name: Pentadactyl Location: ${PROFILE_EXTENSIONS}/pentadac...@dactyl.googlecode.com.xpi Status: enabled Name: Pocket Location: ${PROFILE_EXTENSIONS}/fire...@getpocket.com.xpi Status: user-disabled Name: uBlock Origin Location: ${PROFILE_EXTENSIONS}/ublo...@raymondhill.net.xpi Status: enabled Name: uMatrix Location: ${PROFILE_EXTENSIONS}/umat...@raymondhill.net.xpi Status: enabled Name: Web Compat Location: ${PROFILE_EXTENSIONS}/webcom...@mozilla.org.xpi Status: enabled -- Plugins information Name: Shockwave Flash (11.2.202.643) Location: /usr/lib/flashplayer-mozilla/libflashplayer.so Package: flashplayer-mozilla Status: enabled -- Addons package information ii firefox 49.0-5 amd64 Mozilla Firefox web browser ii flashplayer-mo 3:11.2.202.6 amd64 Macromedia Flash Player -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.7.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: sysvinit (via /sbin/init) Versions of packages firefox depends on: ii debianutils 4.8 ii fontconfig 2.11.0-6.7 ii libasound2 1.1.2-1 ii libatk1.0-0 2.22.0-1 ii libc6 2.24-5 ii libcairo-gobject2 1.14.6-1+b1 ii libcairo2 1.14.6-1+b1 ii libdbus-1-3 1.10.12-1 ii libdbus-glib-1-2 0.108-1 ii libevent-2.0-5 2.0.21-stable-2.1 ii libffi6 3.2.1-6 ii libfontconfig1 2.11.0-6.7 ii libfreetype6 2.6.3-3+b1 ii libgcc1 1:6.2.0-10 ii libgdk-pixbuf2.0-0 2.36.0-1 ii libglib2.0-0 2.50.1-1 ii libgtk-3-0 3.22.2-1 ii libgtk2.0-0 2.24.31-1 ii libhunspell-1.4-0 1.4.1-2+b1 ii libnspr4 2:4.12-6 ii libnss3 2:3.26.2-1 ii libpango-1.0-0 1.40.3-3 ii libsqlite3-0 3.15.0-1 ii libstartup-notification0 0.12-4 ii libstdc++6 6.2.0-10 ii libvpx4 1.6.0-2 ii libx11-6 2:1.6.3-1 ii libxcomposite1 1:0.4.4-1 ii libxdamage1 1:1.1.4-2+b1 ii libxext6 2:1.3.3-1 ii libxfixes3 1:5.0.2-1 ii libxrender1 1:0.9.9-2 ii libxt6 1:1.1.5-1 ii procps 2:3.3.12-2 ii zlib1g 1:1.2.8.dfsg-2+b3 firefox recommends no packages.
