In this example, stable was updated on 16 August for the current architecture.
Alternatively, you can see the same info from the version dropdown on the top right of https://snapcraft.io/firefox.
If you meant how to find out if your installed version of the Firefox snap is using core20 or core22, you can run snap connections firefox | grep 'gnome-'; then if you see gnome-3-38-2004 it means your Firefox snap is based on core20, and if you see gnome-42-2204 it means it’s based on core22.
@bandali Appreciate that, I’m not much of a snap user; basically only when my distro more or less backs me into a corner and the alternatives seem worse-supported.
Using snap info --verbose firefox | grep base: will show you the base a snap uses, so you don’t need to rely on the extension and it is a bit less complicated to obtain too
For stable releases, commits to the stable branch of the canonical/firefox-snap repo trigger builds which are uploaded to latest/candidate, which can then be promoted to latest/stable by the Mozilla folks at their discretion.
For Ubuntu 22.04 the correct channel is not but latest/stable, but latest/stable/ubuntu-22.04:
sudo snap refresh firefox --channel=latest/stable/ubuntu-22.04
Indeed, that is more accurate. But those branches are generally not advertised, so to avoid confusion I simplified a bit and just mentioned latest/stable. (Under normal circumstances, these release-specific branches all point to latest/stable itself, except when a hotfix is needed for a specific Ubuntu release, or if we’d like to role out a newer version of the package for some releases, like we did for core22-based Firefox for lunar and mantic.)
As a final update on this, given that the upgrade for Firefox stable’s base from core20 to core22 went smoothly, I merged the pull request for upgrading Firefox ESR snap’s base to core22 today, and future Firefox ESR snap builds for 115esr and later will be based on core22. This completes our work on upgrading the base snap for all Firefox snap variants (stable, beta, nightly, and now ESR soon as well) to core22.
Thanks to all for your feedback and help with testing these changes.
It looks like I have an issue, started about the related times of the upgrade to core22. It’s a visual (CSS?) glitch, on all/most the sites about rounded corners (partly are not rounded and are changing on hovering):
Hi @bdcomp, sorry for my slow reply, I missed your message earlier. Are you still experiencing the issue? I’m a bit skeptical that it would be related to the change from core20 to core22, but I may be wrong.
If the issue still remains, would you please open a bug report directly to Mozilla, at https://bugzilla.mozilla.org? Thanks in advance.
