Remove firefox home page message of the day

How to change the "message of the day" on the firefox browser home page ?

What I mean by "message of the day" is the quote shown under the search bar in the home page, as shown in the picture below :

For instance, is there any options in about:config that can be modified for that purpose ?

By inspecting about:home sources (view-source:about:home) it looks like it is shown in the snippetContainer element. So I looked up in the about:config for snippet-related settings and only found the browser.aboutHomeSnippets.updateUrl key.

I tried to update it with another url (for instance http://api.forismatic.com/api/1.0/?method=getQuote&lang=en&format=html ) with no success ?

Any idea on how to achieve this ?

Solution 1:

If you hover your mouse over the "Message of the day", you should see a small "X" button appear. Click that and the message should not appear again, even if you close and restart the browser. Just tested under Firefox 52.0.2 64 Bit for Linux.

If that doesn't help, consider getting rid of the start page altogether. I know many people use it to have a search bar at startup, but it isn't needed since typing anything in the address bar will send it to your default search engine, anyway. You can get rid of the start page by going to Preferences > General > Start page and typing in about:blank.
