for some reason all of a sudden in the last week or so on the navigation bar where the spell check is and the form filler and the ad block icons are for the add ons they keep disappearing for that bar. i have to go into the customization section and drag them back to the place i had them. why is this going on. it did not happen until i got a request to update 3.6 i keep using 3.6 because that is the only version that allow the ABC spell check program and the form fill program and the ad block program. i would update to the latest if it would support these programs.
