The issue

Used Firefox to login Utopian.io. The 'Contribution' button doesn't work. When I click 'Contribution' button, there is not response.

The Environment

• Computer: MacBook
• OS: macOS Sierra version10.12.6
• Browser: Firefox 57.0.1

Yesterday, I used the same computer posted an utopian contribution with Firefox. There was no issue. I was able to click the contribution button without any problem.

I tried to reboot the computer, it does not help.

Safari doesn't have this issue. I only got this issue with Firefox.

Workaround

I used the following workaround to post this contribution with Firefox. Click the three dots in the red box in the following screenshot, then click the 'Contribution' in the menu.
