"Submit new issue" button doesn't work in Firefox

[SusiSorglos]

📝 Provide detailed reproduction steps (if any)

In Firefox: Try to create a new issue and click on the "Submit new issue" button.

✔️ Expected result

The new issue should be created.

❌ Actual result

The button becomes disabled and nothing happens - no issue is created.

❓ Possible solution

When I do the same in Chrome it works.
In Firefox developer tools I see some information about CSP but I don't know if this is the cause of the problem.
Maybe the newer posts in the issue #172 are related to this problem.
