This will allow us to load exactly what a crawling robot loads when analyzing the website.
The first thing we need to do is open Firefox and enter this in the URL address:
about:config
Once inside, we will type:
javascript.enabled
Double-click and choose enabled -> false

It will be automatically saved. To deactivate it, we must do the same reverse process.
Now we will reload the web by refreshing it and check which <a> links have been loaded without JavaScript to properly optimize our SEO.
