Hello Team
I just wanted to know if Firefox 128.9.0esr is the latest version for Qubes OS today? As we see, Firefox is the Extended Support Release.
Might I know where can we check if that version is the latest for Qubes OS?
Qubes Update already cares for that Update?
See the link: How to update | Qubes OS
If so then that command: apt update is not recommended? Interesting, but there are arguments for Qubes OS.
Thanks for your reply here.
Kind regards,
AC
I don’t think the Firefox version is related to Qubes OS, because the version is managed by either Fedora or Debian, depending on the template used to launch Firefox.
I don’t understand the other questions as the docs seem clear enough to me. apt update is not recommended but updates will be managed by the Qube Update tool.
Thanks @parulin for your response. I thought that Qubes Update Tool also cares for updating Firefox… so if not, I just need to upgrade it. Would that be the simplest way on any template: sudo apt-get update then sudo apt-get --only-upgrade install firefox?
QubesUpdate – as you wrote – updates your templates. It should see if there are (distribution) updates available. So if firefox-esr is installed in your template and an update is available, QubesUpdate should step in.
Debian, which your template is based on (assumed from use of apt) tracks Firefox ESR which currently maxes out at 128.9.0
Next ESR release bump is not due until June 24
But Debian tends to stick to the current ESR until its last release which looks to be August 19 instead of jumping straight to the newer ESR
If you would prefer to move off ESR you can use Mozilla’s APT repository to get the most recent non ESR release

Thanks @curbs94
Indeed. That is also because of Security reason of Qubes OS, so Firefox with ESR. 
And yes, when we want to have the newest version of Firefox, I think this is the best way:
https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions-recommended
Because this one is obsolete?

I assume, after this action, I would have Firefox with the newest version and Firefox ESR in addition, so in parallel way, right?
Yes. Why not go for Librewolf though, if you’re going to install an additional browser?
Good point @barto. I am gonna install LibreWolf Browser.
If (for whatever reason) it doesn’t fit your needs, you could try firefox profilemaker:
no, it’s purely the decision of Debian that Firefox tracks ESR
