Comment 10 for bug 1970989

The increased startup time is [a known issue](https://forum.snapcraft.io/t/slow-cold-start-of-snap-firefox-on-ubuntu-21-10/27052), although it seems to be hard to nail down because observations are inconsistent from one user/machine to the next. But it is definitely something that needs to be addressed.

It would be helpful if you could quantify this "very long startup time" in your specific case, and share details about your hardware.

It would also be helpful if you could test the snap in the candidate channel (to be promoted to stable tomorrow when Firefox 100.0 is released) and let us know whether you're seeing a significant difference in startup time (bonus points for comparative measurements):

    sudo snap refresh firefox --candidate

Can you elaborate on the increased CPU, I/O, memory and energy consumption you're seeing? This is definitely not expected.
