Ff extension: "Installation aborted because the add-on appears to be corrupt"

[momo1958]

Hello,

As the title says, on Firefox AMO (https://addons.mozilla.org/en-US/firefox/addon/simple-modify-header/):

Installation aborted because the add-on appears to be corrupt.

I ve just install it with a new install of last version of firefox (126.0) and had no problem

it seems the problem is not due to the extension itself , similar problem has been reported for other extensions : https://forums.opensuse.org/t/firefox-addon-installation-aborted-corrupt-addon/173283/2
