Today downloaded a plug-in (crx file) a Google browser installed according to the original way,
Turn on the expansion program interface
Drag and drop files directly to Google crx extension interface browser. Version is slightly older version is still possible, but some of the updated version has to die (I was 68 version).
You can not drag and drop install, then we can find other way.
A method, modify the browser parameters

Parameter modification page
Extensions that item will be changed Enabled, and then be prompted to restart your browser, you can restart, and then you can drag the plug-in installed.
