Warning when Chrome attempts to install .crx (load unzipped extension)

Because of the well-known problems in the use of Chrome's online store in China, in order to install the impression note extension on Chrome

After I found a place to download extiension_6_12.crx, the following problems occurred when I installed the extension

The following warning appears when you try to install this extension:

_ metadata is a reserved directory that will not be allowed at the time of Chrome Web Store upload.

This problem occurred because I forcibly extracted .crx into a folder and then loaded the unzipped directory in the Chrome extension.

Select the .crx extract directory in the interface below.

As a result, although it works, it doesn't work to open the browser again.

If you want to use it normally,

Please change the _ metadata folder in this folder to metadata (remove the first underscore _)

Then load the extracted extension again. In this way, I can solve this problem perfectly.

You think this is the end?

The next thing I found out, I was already crying. > _
