Install the extension for the Chrome browser

Open Chrome browser: Select More Tools -> Extensions.

Under normal circumstances, it is enough to drag and drop the crx file directly into the browser, but the latest version of Chrome does not seem to be able to use it like this.

So you can use the second way: change the suffix of the crx file to zip or rar (not to add to the compressed file, but to change the suffix!),

Then unzip it. In the extension bar of the browser, click on developer mode and select "Load unpacked extension".
