Below is the test I performed in a Qemu virtual environment. Host : a Debian host. Guest : Debian bookworm x86_64, LXQT, deinstalled preload and firefox-esr for light desktop.
On the guest I installed 2 flavours of the same 100.0 version of Firefox on : - the snap : 100.0-2 (snap revision 1300) with the other required snaps (gnome-3-38-2004 0+git.1f9014a rev 99, gtk-common-themes 0.1-59-g7bca6ae rev 1519, core20 20220329 rev 1434) - the deb package by hand from sid repository : 100.0-1. Before starting the test, I started for the first time each flavour and I made the new page empty (no web search, no shortcut or recent activity). I performed the below sequence with each flavour : 0. The host is up to date from the day (snap refresh, apt update), no background task expected, no other application on host and guest desktops. 1. I start AQemu. 2. I launch the virtual machine with Debian bookworm. 3. I login into the guest desktop environment. 4. I wait for roughly 60 s (stopwatch in hand). 5. I launch Firefox by the desktop menu entry and measure the start-up duration until the window appears. 6. I close Firefox and wait roughly 30s (stopwatch in hand). 7. I launch Firefox again and measure. 8. I close Firefox and wait roughly 30s (stopwatch in hand). 9. I launch Firefox again and measure. In the case of the deb package application : 5. gives 2.5 s 7. gives 1.7 s 9. gives 1,6 s In the case of the snap package application : 5. gives 5.9 s 7. gives 4.1 s 9. gives 4.3 s -- 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/1970989 Title: missing a tightly integrated deb package without snap Status in Mozilla Firefox: New Status in firefox package in Ubuntu: New Bug description: I installed the Jammy Jellyfish version. When I launch firefox, the delay between my click and the apparition of the window is very long compared to the behaviour of the previous versions of Ubuntu. The deb package is just pulling the firefox snap. Why did you decide this performance regression ?! I don't understand.
