With the icon, we do not have to guess.
Let us use this Brave Browser webpage, re this issue:
When the icon is present, I know that I need to copy:
and enter that as
to be enabled, at:
Settings > Additional settings > Privacy and security > Site and Shield Settings > JavaScript
I have been doing that, for a long time, now.
It works; and I do not have to guess about the JavaScript status.
But now, with the icon missing, I have to wonder, Do I need to enable JavaScript for this website? Wander up and down a webpage - and guess, maybe / maybe not. Cannot tell, at a glance.
Spend more time wondering, than getting to the Settings > . . .
