It crashes the manifest v3 extensions and please remove this extension from app store.
Guokai Han (Jackie)
Don't use it, this app is very deprecated by Google. And it causes other manifest V3 extensions crash (when send a message). See https://bugs.chromium.org/p/chromium/issues/detail?id=1180566
Dan Bugglin
This 2014 app seems to break modern extension development causing them to crash. Do not use. The capabilities are built into Chrome now anyway.

Evertime i click the load unpacked button nothing happens. Apparently it is supposed to load some kind of file browser so i can select the correct file and load it into the application, however when i click nothing happens.

It is simply a windowed version of the Extensions page—which is better than going to the extensions page itself. However, this sometimes happens. When I import an extension, it rather deletes its source file, making it unable to import. Now I was not able to find that extension anywhere, and by the way, I am using M70 (as I liked the old UI of Google Chrome by turning on a 'flag'). You can't also pack an app that is not on the list, but in my opinion, that would be fine especially if you are just packing those you have added in the web browser and the Extension DevTools app.

Hi, can we get a new version of this? Since Google's pushing out more Chromebooks now it might be a good time to do something for developers

Useful, but it's difficult to understand what an extension is doing. Please allow filtering by event type so that it would be easier to find malware extensions.

I'm not sure that some people realize that they aren't supposed to be unpacking "Chrome Apps & Extensions Developer Tools" itself (or it's id#). It's for extensions that are in developments.
