Why is Run button disabled?

[numeralnathan]

I have several scripts that run perfectly. I created a new script that matches a page. However, it won't run. The manual "Run" button is disabled. How do I figure out why the Run button is disabled?

Run button is disabled when the script is already injected into that page via automatic injection.

You should see that the script is active.

How do I see that the script is active? Do you mean that it appears in the Tabs & Scripts section of in the Fire Monkey drop down?

It would appear in Tabs Scripts & CSS with a ✔️ next to it to show that it is enabled and active on that page.
