[Affected versions]: - Nightly 55.0a1 [Affected platforms]: - All [Steps to reproduce]: 1. Launch the latest Nightly 2. Enable the Menu Bar 3. Go to Bookmarks -> Firefox Nightly Resources and look at the Favicons of: - All your crashes - Discuss Nightly on IRC - Planet Mozilla 4. In new tabs, open the above mentioned bookmarked pages 5. Observe the Favicons [Expected result]: - Steps 3 and 5: The favicons of the 3 bookmarked pages should be the same. [Actual result]: - Steps 3 and 5: the favicons of the 3 bookmarked pages from the Bookmarks Menu are not the same with the favicons displayed on the tabs.

the favicons may not be the same, the tab could use different icons from the bookmarks views. The reason is the way the favicons are defined, in this case we likely preferred the root domain icon because it has better resolution than the Planet icon. I'm not sure whether we want to do anything about this.

let's keep this open to track the root VS site favicon. Some of the reported cases are already fixed, fwiw.
