Why can't I install AdBlock Plus? I keep getting the message that the signing cannot be verified, but I'm getting the download from the Mozilla site.

I have tried to install AdBlock Plus from the list of Add-ons on Mozilla, but I keep getting a message that the installation was not allowed because signing could not be verified.

If its asking about the author verification then you can simply allow and install.

If you have a program called "TDC Digital Signatur" installed on your computer, it may interfere with critical parts of Firefox, including add-on compatibility check, add-on update and Firefox update.

You can try installing it from AdblockPlus website: http://adblockplus.org/en/
