It is more of Facebook fault, really, because I have had the same experience with another browser app that eventually bit the dust, but still, people need to know. Things that don't work: occasionally, photos won't attach to posts. They just won't. You select a photo, confirm, and nothing happens. Another thing: you write a long comment, publish it, and only the first word shows. The rest is lost and gone. Also, as of last month, ads and commercial posts show up in every third post in the feed.
