Alternatively, in-place release upgrade is possible upgrade using by performing a release upgrade.
Availability and Qubes-Whonix Support: Qubes R4.2 versus Qubes R4.3?
Qubes R4.2: Qubes-Whonix 18 unavailable. Qubes-Whonix 18 won’t be available for Qubes R4.2.
Release status: Even though Qubes R4.3 is only available as a r elease c andidate (RC) at the time of writing,
Expected release: A stable release of Qubes R4.3 (and Qubes-Whonix 18) is probably not far away.
Upgrade recommendation: Qubes-Whonix 17 users on Qubes R4.2 are encouraged to consider upgrading to Qubes-Whonix 18 on Qubes R4.3 as soon as possible.
Maintenance situation: Qubes-Whonix 18 is what developers are using and where the development focus is. It comes with much newer packages. Qubes-Whonix is a small project and does not have a dedicated team for oldstable support. Therefore, oldstable support is maintained as a side project. More details: decide availability of Kicksecure and Whonix 18 (Debian trixie based) on Qubes R4.2 versus R4.3 #10219
Qubes R4.3: Qubes-Whonix 18 is available.
This release would not have been possible without the numerous supporters of Whonix!

right?

On Firefox the mouse scroll wheel lags so much it becomes unusable. It works on other apps like FeatherPad.
But the lag extends to everything, like dragging a window. No more graphic board hardware support?
Overall the change from Xfce to LXQt is a big downgrade.

Why would you use Firefox inside Whonix?

Are you talking about Non-Qubes-Whonix or Qubes-Whonix?
Sounds like lag caused by improved protections for Keystroke and Mouse Deanonymization .
