After a new installation of Firefox I tried to install Add-On. For all Add-Ons I tried it fails with the message as in the picture attached. When I install it on other computer where I also have Firefox no problem occurs. The picture shows the AdBlocker add-on, which is widely used and to my opinion cannot be corrupted. The error-message is in Dutch and my English translation would be: "Installation is cancelled because the Add-On seems to be corrupted".
Do have a solution/explanation?
