A recent unwanted Firefox for Android automatic update has replaced all the open tabs and history with a different set of tabs and history. The tabs and history I had before the automatic update are now gone and in their place are a set of tabs which I had in a previous install of Firefox on the same device, but some time ago. Some of the tabs I had open in the session before were important (reminders, notes for things, pages I needed to look at for various reasons, etc.). Any ideas how I can get this session back? Some ideas: How do I find out the version of Firefox that was installed prior to the automatic update, for the purpose of reverting to it and hoping the previous tabs are there? Is it possible that data for two Firefox installations are on the phone, even though only one installation is listed? This must be the case with histories and tabs because a bunch of old tabs and an old history have appeared along with the automatic update. Any idea where this data is stored with Firefox Android? I'm not too worried about the history. I had that synced anyway. The open tabs is the main thing. Thanks for any help. PS. Any other users who wish to avoid this happening please note, automatic updates can be turned off in the google play store app, in settings. You can then backup your tabs if and when you wish to update Firefox.
