[Affected versions]: - Firefox 51.0.1 - Firefox 52 beta 5 - latest Aurora 53.0a2 - latest Nightly 54.0a1 [Affected platforms]: - all [Steps to reproduce]: 1. Open Firefox with a new profile 2. Open a website and bookmark it in Bookmarks Menu 3. Bookmark another website in Other Bookmarks (where it is saved by default) 4. From the toolbar, click the Bookmarks Menu button 5. Right click on "Recently Bookmarked" section and select "Open All in Tabs". [Expected result]: - The "Open All in Tabs" option should be grayed out in Recently Bookmarked section, as it may be confusing for an user who may expect for those recent bookmarks that appear in the list to be open OR - All the bookmarks from the "Recently Bookmarked" section are opened in separate tabs. [Actual result]: - The bookmarks saved in Bookmarks Menu are opened in new tabs [Regression range]: - It's not a regression, the behavior is the same in Firefox 49 where Recently Bookmarked section was introduced
This context menu item only shows up on the (disabled) section header. It also appears when you right-click e.g. on the fixed separators in the menu, and in that sense this is not a regression even by the 'recently bookmarked' addition. Doesn't seem critical to address -> P3.
