The add-on downloaded from agilebits.com could not be installed because it appears to be corrupt

@Kactus: Either there's something wrong with your internet connection, or something is actively interfering with your ability to connect to our site securely and download it properly. So you have "security" software installed that's trying to insert itself into your connection? Ultimately you should be able to download the Firefox extension using another browser and then drag it to Firefox...but I'd be more concerned about why you're not able to do so normally in Firefox itself. Let me know what you find!

Thanks for your help, Was able to down file using another browser and install it into Firefox

@Kactus: Glad that helped! I'd still suggest looking into what's messing up Firefox for you though, as it likely involves tampering with the browser's security.

No luck for me. I'm getting the "add-on is corrupt" error, too. I've refreshed firefox, I have a good internet connection, I don't have an anti-virus enabled to interfere, and I've downloaded the .xpi in Chrome and tried to install the file into firefox. All of them fail because of the "add-on is corrupt" error. Any other ideas?

@MattOKC: If you create a new Firefox profile and you're still seeing the same error, something is interfering with the download. What "security" software are you using?

MattOKC

I'm on a mac, so I use sophos free for antivirus. Thanks!

@MattOKC: If you disable it, does that allow you to download the extension successfully? I wonder if you'd be able to set an exception for our file server. You could probably download the extension using another browser and then drag it to Firefox to install it, but if I were you I'd be curious about why they'd be interfering with your secure communications. Maybe they're trying to decrypt the traffic to "scan" it. Not something I'd be comfortable with since the whole point of web security is to ensure that the connection is end-to-end encrypted and only you and the site you're communicating with can read it. But it's unfortunately not uncommon behaviour these days.

I found this thread because I was experiencing the same issue. Turns out my browser was horrifically out of date because I hadn't been using Firefox as my default browser for so long. Once I updated Firefox, I was able to install the extension with no problem. Hope this helps the next person that finds this.

Awesome! Glad to hear that did the trick for you. I tend to switch to different browsers from time to time too (I'd been using Vivaldi but recently switched back to Firefox) and find the others get woefully out of date while I'm off playing with one for a while -- and sometimes won't even update on their own anymore as a result. Never hurts to grab the latest from the website. Cheers! :)
