Bug 1410378 - Help Needed

[Vikas Mahato]

Hello Developers,
When I try to run this code https://pastebin.com/fdDK0wNj in a new tab of firefox, both Title and URL fields get cleared and it shows an error message. Inshort I am not able to create a new topsite entry using javascript.
Steps to reproduce:

1. Open a new tab in firefox

2. Open the javascript console

3. Paste the following code in console https://pastebin.com/fdDK0wNj  and hit enter.

If you comment out the last line you'll see that the fields are populated. But upon executing the click event on the add button both the fields get cleared and cause the error message to show up.

More details can be found here https://bugzilla.mozilla.org/show_bug.cgi?id=1410378 

Regards,

I found the fix. I had to manually trigger an event after setting the title and url values using
fieldURL.dispatchEvent(new Event('input', {bubbles:true}));

Regard,
