Then I went to reinstall them and on their extensions page am getting "Installation aborted because the add-on appears to be corrupt."
Can anyone else verify this or is this just specially for me?
TIA

This link has more useful information - but the short answer is to update Firefox or switch to the latest ESR 115 if you're on an OS that isn't supported by the latest versions.
