I try to download my own extension for testing, but i receive this error message “Installation aborted because the add-on appears to be corrupt.”. I check all my files, but nothing are different than before when it’s running perfectly. I remove my addons and repost in the store, but the error come back. Someone could help me ?
I downloaded “midip-1.0.0.xpi” from https://addons.mozilla.org/en-US/firefox/addon/midip/ and unzipped it.
When I loaded it as a temporary extension, Firefox showed an error message.
Error message text:
There was an error during the temporary add-on installation.
Error details
