Does not allow debugging when response header is content-type json

[sneakingJ]

When you set the response header for example to 'Content-type', 'application/json; charset=utf-8', you can't activate the debug helper in browser tab.

confirmed, same problem

what was the full URL of page you were visiting, it should appear for any url containing http/https

[sneakingJ]

It was an internal URL I used for developing. But the issue is the case for every page that outputs in json, like this: https://jsonplaceholder.typicode.com/posts

I have the same problem debugging an API. As a workaround, I navigated to the site's homepage/documentation page and enabled the debugging icon there. I then navigated to the API endpoint and my IDE started debugging properly.

Same problem, the icon does not change to green when i click on it

+1 to this issue, JSON content types will not work with this extension

Seems related to Firefox Json viewer 🤔
Here my workaround:

• Go to about:config
• Search for devtools.jsonview.enabled and disable it
• Install an other Json viewer (Json-lite do the job for me)

Workaround with disabling jsonview worked, however permanent solution would be great as debugging APIs are getting more common.

This issue is still occurring. I notice this has been arround for over 3.5 years, should we assume this is a WONTFIX?

I'd still love to see this fixed :)
