Feature Freeze Exception: Seeding the official Firefox snap in Ubuntu Desktop

I’m experiencing very slow startup times with Firefox as Snap compared to FF as Deb. As a testcase, I started both variants after booting without launching any other applications (“cold start”), compared with starting them when they had been already running (“warm start”). To rule out outliers, I did more than one run for each test (rebooting three times):

Snap cold start: 20 | 23 | 19
Snap warm start: 8.8 | 9.9 | 9.8 | 10.1
Deb cold start: 3 | 3.2 | 3.2
Deb warm start: 2.2 | 2.3

All times in seconds.

My test setup/system:

  • Kubuntu 22.04 Plasma Wayland session
  • fresh Firefox profiles
  • Intel Core2Quad Q9550
  • 8 GB RAM
  • SSD drive

Any chance this will get better or be fixed until the final release?

Kind regards, Jan
