Firefox rolled back on its own

I have been running FF12 for some time. I do not update early as there are always issues with parts of my Norton Internet Security, so I wait until the various issues are sorted out before updating.

A couple of days ago I was using my laptop with no problems. I shut it down in the evening and when I started it up the next morning the Norton toolbar was missing and Norton Identity Safe was not working. This is the main reason why i don’t update FF as soon as you release an update. After doing some checking, I found that the version of Firefox that my computer had loaded was v10! I had been running FF12 for quite some time before this happened. I re-installed FF12 and all was well again.

I then went to my desktop that I only use for photo editing. Exactly the same thing had happened! Since I last used it, it had gone from FF12 to FF10.

Now for two separate computers to do the same thing cannot be a co incidence.

I’ll assume that there is nothing within FF that will instigate this if an update is not downloaded, so I’m wondering if when FF is updated, should the old version be uninstalled first? Does installing a new version over-write the old one, or do they exist side by side on the computer?

Installing a new version overwrites the old version. I could have been some system restore that caused this (just a guess). In any case, you should be able to safely update to Firefox 13 and update Norton as it's already compatible.

Thanks for your input Verdi. If it only happened to my laptop, I also might have thought that there had been some sort of restore done, but I only switched it off one day and switched on the next day. No other functions were affected, just FF went from v12 that had been in use for some time to v10. For this identical occurrence to have also happened to an independent desktop too cannot be a coincidence. There must be something in FF that caused it to happen.

was this happening in a corporate environment, where admins or the tech department could have switched to version 10 (maybe the ESR release)?

Do you have any security software that may undo changes and restore a previous setup?

Thanks for your time guys. Not a corporate environment. Both computers are used at home, I am the admin.

I'm using Norton Internet Security 2012 on the laptop since around October 2011. Before that NIS for six or seven years. Never had this before. Only problems I've had with Identity Safe and the Norton toolbar not appearing have been if I updated FF too soon and the Norton patches were not available. The desktop was new last year and is also running Norton Internet Security 2012. This machine is principally used for photo editing and is only used a couple of times a week. The laptop is a daily use workhorse. Both machines are independent of each other other than using my wireless network, yet both went from FF12 to FF10 at the same time with no input from me, no restore and no one else using them.

Spooky, isn't it?
