Be careful with old versions!
These versions are displayed for reference and testing purposes. You should always use the latest version of an add-on.
You should go to about:config search for extensions.nuke_anything_enhanced.autoblink and set it to empty.
If you want less intrusive blinking you can set it to "3px solid #ccc" or "1px dashed red" without quotes.
