Thank you for your bug report, is slack explicitly asking for the profile 'default'? Or are you just reporting that it opens the wrong profile?
The profile naming changed recently upstream, see https://support.mozilla.org/gl/questions/1264072 If the issue is the wrong profile it sounds similar to bug #1835024 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1901959 Title: Default Profile is called "default-release", programs like Slack open links with different "default" profile Status in firefox package in Ubuntu: New Bug description: Firefox 82.0 Ubuntu 20.04 The default profile in the Ubuntu Firefox package is called "default- release", while the typical profile name for Firefox is "default". Slack opens links using the default profile when Firefox is the browser, causing links to open in a different profile than normal without the extensions , history, etc. from the normal browsing profile. To reproduce: - Set up Firefox in Ubuntu , run session to generate profile, install extensions - Install Slack from snap : snap install slack - Firefox as default browser in Ubuntu - Open link in Slack Slack opens the "default" profile of Firefox, which is different than the "default-release" that the Ubuntu firefox package defaults to. Expected: Ubuntu Firefox uses the normal "default" profile as default.
