I thought v4.3 have as default Brave, and WaterFox as pre-installations. I still see FireFox?
The official Qubes templates inherit the default browsers from their respective upstream OS projects (Fedora and Debian).
Do you think that on future version will change onto better ones?
You need to ask this to the Fedora or Debian devs.
This is not so.
This will depend on what “better” means here.
As @adw the official templates bear the default browsers from upstream.
It would be simple to change to, or add, some other browser in the
template, but this is easily done by users who want that.
I never presume to speak for the Qubes team.
When I comment in the Forum I speak for myself.
And another things i noticed of QubesOS v4.3 that Fedora is v42, and it is not v44?
I think the ISO will be updated soon to include Fedora-43, but even recently only included Fedora-42, so has been a bit behind. You can list and install templates in dom0 with:
qvm-template list | grep fedora
qvm-template install fedora-43
Regarding browsers. One can always install a minimal template and then install a browser of choice. Debian has a list of browsers available from their repos, but also Brave and Librewolf available with extrepo (not sure about WaterFox… Edit: waterfox is available as a flatpak, but not with extrepo).

Trivalent works fine as well.
This is unlikely to be initiated on the Qubes side, given the project’s attitude toward changing guest distros and the fact that many users with incompatible preferences would all like their preference to be made the default. However, you’re always free to install and use whichever browser you like.
At the moment, both Fedora 42 and 43 are supported on Qubes 4.3. However, Fedora 42 will reach end of life very soon, at which point it will no longer be supported. The Fedora 44 template is still in development, and some advanced users have begun testing it. When the template is ready to be tested more broadly, we’ll make an announcement in the Testing Team category. When the template is ready for stable release, we’ll make a News announcement.
