Convenient little wrapper-app of Facebook’s messenger.com interface, which Facebook’s login notification recognizes as Safari, with a modest handful of missing elements and buggy behavior—at least on my Yosemite-running iMac—which I will note here: • Messengers options for cam & audio calling are absent. • Right-clicking text in the input field—in order to spell-correct, for example—does not open the “Ignore spelling, Learn spelling, Cut, Copy, Paste…” dropdown menu that it should. • Trying to place emojis with Mac’s native emoji popup doesn’t work. Selecting the emoji places it in the text input field, only to immediately disappear afterwards. All in all, it’s convenient and fits the Messenger brand, and it’s nice to have it liberated from my browser tabs. This app IS free, so in light of that fact, my minor quibbles above aren’t necessarily expected to be corrected.
