I'm trying to install the 1Password extension in Firefox but it keeps giving me the message "Installation aborted because the add-on appears to be corrupt". I have the latest version of Firefox and I have successfully installed the plug-in on Chrome (so it's not my security software). I read through all the previous discussions on the same topic but no clear solution is presented anywhere.
1Password Version: Windows 8.6.0
Extension Version: Not Provided
OS Version: Windows 10
