When opening a folder of bookmarks in tabs, all other open tabs will be closed, and only the bookmarked sites will remain. This seems rather not cool.
Please see: https://bugzilla.mozilla.org/show_bug.cgi?id=216346 https://bugzilla.mozilla.org/show_bug.cgi?id=175124 Firefox developers have decided that the current functionality won't be changed until 2.0. There is a 'browser.tabs.loadFolderAndReplace' preference that can be set in user.js or about:config. Propose closing bug and marking as UPSTREAM or NEXTRELEASE/DEFFERED. Alternatively, we can decide if that preference should default to 'false' in Fedora's configuration.
