** Summary changed: - JS error crashes Firefox + Firefox fails to start ** Package changed: ubuntu => firefox (Ubuntu) -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1995729 Title: Firefox fails to start Status in firefox package in Ubuntu: Incomplete Bug description: I have a ".desktop" file which opens Firefox. I click the file and I see the mouse cursor icon is change to a "loading" icon, but firefox window doesn't appear. The loading icon continues for a few seconds (about 10sec) and then the normal cursor icon is seen. Overall, Firefox doesn't appear. This issue started just recently, in the last week (probably due to an upgrade, I assume). This issue happen only sometimes - meaning, sometimes when I click the ".desktop" file then firefox starts normally, but in some other times then Firefox will not appear. I performed some debug and found out the it is related to the gnome-shell program, or more specifically to the extension "ubuntu-dock". By inspecting the file "/var/log/syslog", whenever the issue happens, then the following error appears in the file (omitted irrelevant data): " gnome-shell[2129]: JS ERROR: TypeError: window is undefined#012activateWindow@resource:///org/gnome/shell/ui/main.js:764:30#012IsolatedOverview@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/docking.js:1546:29#012_create/object[name]@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/utils.js:290:68#012launchNewWindow@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/appIcons.js:677:26#012activate@/usr/share/gnome-shell/extensions/ubuntu-d...@ubuntu.com/appIcons.js:615:18#012vfunc_clicked@resource:///org/gnome/shell/ui/appDisplay.js:3168:14 " ----------------------------- Info according to the guidelines: 1) $ lsb_release -rd Description: Ubuntu 22.04.1 LTS Release: 22.04 2) $ apt-cache policy "gnome-shell-extension-ubuntu-dock" gnome-shell-extension-ubuntu-dock: Installed: 72~ubuntu5.22.04.1 Candidate: 72~ubuntu5.22.04.1 Version table: *** 72~ubuntu5.22.04.1 500 500 http://il.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages 500 http://il.archive.ubuntu.com/ubuntu jammy-updates/main i386 Packages 100 /var/lib/dpkg/status 72~ubuntu5 500 500 http://il.archive.ubuntu.com/ubuntu jammy/main amd64 Packages 500 http://il.archive.ubuntu.com/ubuntu jammy/main i386 Packages 3) I expected a Firefox window to appear. 4) Instead, a Firefox window doesn't appear.
