Pinning a sponsored topsite will lose their favicon and replace it with website’s first letter
There are sponsored tiles listed in the topsites.
- Download and install RO localized Firefox.
- Create an user.js and set: browser.topsites.useRemoteSetting = true and browser.search.region to "RO", connecting to the staging main-preview.
- Start the browser with the predefined profile.
- Open a new tab.
- Pick any sponsored topsite and choose to pin it using the menu.
Intermittently, the topsite loses it’s favicon which is replaced with a general icon containing the website's first letter.
The favicon is not lost when the sponsored topsite is pinned.
