The Mac Safari version is 17.0.
To enable developer options, go to the menu, select "Advanced," and check "Develop."
You can inspect web page requests by right-clicking in the web page and selecting "Inspect Element" from the menu. In the "Network" tab, you can capture the page's request messages. However, it seems that Safari does not have a "View Source" option.
Is it the case that Safari does not have this option?
Not having this option can be quite inconvenient.
