That's a firefox issue, the problem is there https://sources.debian.org/src/firefox/82.0-1/toolkit/profile/nsToolkitProfileService.cpp/?hl=1840#L1823
The classic snap call the default browser from the system but from the snap environment that has SNAP_NAME defined or firefox has code to disable profiles in such cases... The issue is easy to trigger using the deb, just do 'SNAP_NAME=bug firefox https://www.ubuntu.com' ** Summary changed: - Links triggered within most snap apps open in a separate browser session + firefox fails to use the default profile from classic snaps ** Package changed: xdg-utils (Ubuntu) => firefox (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1835024 Title: firefox fails to use the default profile from classic snaps To manage notifications about this bug go to: https://bugs.launchpad.net/snapd/+bug/1835024/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
