I have made a manual regression range: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=738c0a460acb30ab2ab419f4c0dc93fa9af200d6&tochange=5c56b92baa65aa27df61f84718594767ef8f26f4 Nightly builds between 2023-09-4 and 2023-09-06 does not install the Default browser agen task for some reason in my case so I extended the regression range. Looking at the pushlog maybe bug 1838754 may be the regressor?
