Package: thunderbird Version: 1:68.7.0-1 Severity: important Whenever I click on a hyperlink, like inside a message, or even at the "Mozilla"-Link of the "Help > About Thunderbird" dialog, the link will not be opened by my browser. Instead, "Verifying the feed..." gets displayed at the taskbar, immediately followd by "https://mozilla.org/ is not a valid feed."
It seems that Thunderbird handles all links as if they were feeds.

Not being able to open links by clicking on them but being forced to copy them over into the browser is a major usability issue. I am able to reproduce this bug with a fresh profile. -- System Information: Debian Release: bullseye/sid APT prefers testing APT policy: (500, 'testing'), (50, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 5.4.0-4-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en (charmap=UTF-8) Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages thunderbird depends on: ii debianutils 4.9.1 ii fontconfig 2.13.1-2+b1 ii libatk1.0-0 2.36.0-2 ii libc6 2.30-4 ii libcairo-gobject2 1.16.0-4 ii libcairo2 1.16.0-4 ii libdbus-1-3 1.12.16-2 ii libdbus-glib-1-2 0.110-5 ii libevent-2.1-7 2.1.11-stable-1 ii libffi7 3.3-4 ii libfontconfig1 2.13.1-2+b1 ii libfreetype6 2.10.1-2 ii libgcc-s1 10-20200411-1 ii libgdk-pixbuf2.0-0 2.40.0+dfsg-4 ii libglib2.0-0 2.64.1-1 ii libgtk-3-0 3.24.18-1 ii libgtk2.0-0 2.24.32-4 ii libicu63 63.2-3 ii libjsoncpp1 1.7.4-3.1 ii libnspr4 2:4.25-1 ii libnss3 2:3.51-1 ii libpango-1.0-0 1.44.7-3 ii libsqlite3-0 3.31.1-4 ii libstartup-notification0 0.12-6 ii libstdc++6 10-20200411-1 ii libvpx6 1.8.2-1 ii libx11-6 2:1.6.9-2 ii libx11-xcb1 2:1.6.9-2 ii libxcb-shm0 1.14-2 ii libxcb1 1.14-2 ii libxext6 2:1.3.3-1+b2 ii libxrender1 1:0.9.10-1 ii libxt6 1:1.1.5-1+b3 ii psmisc 23.3-1 ii x11-utils 7.7+5 ii zlib1g 1:1.2.11.dfsg-2 Versions of packages thunderbird recommends: ii hunspell-de-de [hunspell-dictionary] 20161207-7 ii hunspell-en-us [hunspell-dictionary] 1:2019.10.06-1 ii lightning 1:68.7.0-1 Versions of packages thunderbird suggests: ii apparmor 2.13.4-1+b1 pn fonts-lyx <none> ii libgssapi-krb5-2 1.17-7 -- no debconf information
