Support for Shell Extensions was removed from GNOME Software since 3.36 (because it was problematic and hard to maintain). I just checked it in the latest stable Snap Store app and was not able to find any support for Shell Extensions there.
So, I see three possible solutions for this issue: 1. Add downstream support for Shell Extensions to GNOME Software / Snap Store on Ubuntu. (That would bring too much work and possible issues, at least in my opinion.) 2. Add AppStream metadata file to the chrome-gnome-shell package that would display the package as Add-on for something (Firefox?) in Snap Store. 3. If a package from main cannot depend on a package from universe, move gnome-shell-extension-prefs to universe and add chrome-gnome-shell to its dependencies. (That would be the best solution in my opinion.) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to ubuntu-meta in Ubuntu. https://bugs.launchpad.net/bugs/1866841 Title: Add chrome-gnome-shell to ubuntu-desktop recommends Status in One Hundred Papercuts: Opinion Status in chrome-gnome-shell package in Ubuntu: Invalid Status in ubuntu-meta package in Ubuntu: Opinion Bug description: Please, consider adding the chrome-gnome-shell package as a recommended dependency for ubuntu-desktop package in Ubuntu 20.04. The chrome-gnome-shell package provides GNOME Shell integration (connector) for Firefox, Chrome, Chromium and other web browsers that is necessary for users to be able to manage GNOME Shell extensions using a extensions.gnome.org website. Since the Shell Extensions support was removed from gnome-software since 3.36 and the replacement Extensions application cannot be used to find and install new extensions, there is not any user friendly way to install new Shell Extensions without having the chrome-gnome-shell package installed.
