I had many open cards and bookmarks in my Firefox for Android. But today I open Firefox and everything vanished. I haven't got Sync account so I can't synchronised old data. I find support only for Firefox for Windows problem and there is no solution for people which had problems in Android. I can't use about:profiles because it's not working in Firefox for Android. So is there any other options? I haven't removed or uninstall anything and didn't install any new version of Firefox so what could happend and how to fix it? Most important thing for me is to restore my open cards. I had more then 300 of them...
