Hi, Because of reasons my computer needed to be refreshed. My old firefox profile folder was saved though, and with that the bookmarkbackups. As the title says I restored my bookmarks from a resent .json file, but one folder (containing probably about a hundred bookmarks) is now empty and one other is missing completely. In some places I have a 5 levels deep folder structure for my bookmarks, but since the folders missing are from different levels I don't think this is the problem. The now empty folder contained six or seven other folders, that in turn contained a lot of bookmarks with titles including non-alphanumerical characters. †?|&*()<-/., to be precise. However, if I restore a very old .json (from september 2013) the folders are present and contain the mentioned bookmarks - albeit much fewer, since the file is old. A few other bookmarks still present also contain the mentioned characters, so this is probably not the problem either. The folder that is completely missing just contained a lot of bookmarks that were to be sorted. When opening the more recent .json files (I have a whole month of automatic backups to choose from) in the firefox scratchpad it would seem that the bookmarks are missing alltogether, so I suppose that there is not much to do about it (please correct me if I'm wrong), but I definitely want to report the bug. Is there anything at all to do about it? Thanks, Hanna
