I'm unable to install the Temporary Containers add-on when it's downloaded from the AMO page.
Firefox claims that it seems to be "corrupt" for some reason. (Firefox version 88.0)
It seems to not be the xpi/zip file itself that is corrupt, as I could extract the files and re-zip them, but even then it wouldn't be installed, not even as a temporary add-on.
I was able to install your other two add-ons just fine, so it's something that's specific to Temporary Containers.
