Can't install desktop add-on, not compatible with Firefox 72
The desktop add-on cannot be installed because... uh... apparently it's not compatible with 72.0?
Additional System Details

Firefox Lockwise has been built in to desktop Firefox, there's no need to install this addon in this version.
Note that Lockwise is opened as the about:logins page. In Firefox 70 and later builtin Lockwise is enabled by default and the Lockwise extension is disabled and can't be enabled.
