I have been having intermittent problems with my Touchpad over the past two weeks and no changes to the drivers worked. I then carried out a Reset, retaining all my stuff. Something went wrong and although it retained all my docs, photos etc, it lost the profiles and all my saved passwords in Firefox & Chrome. It's a catastrophe. I have backed up my own files every few months but not things like profiles. I have to start again with everything, including Thunderbird. I set up TB yesterdayand have all my 8 email accounts linked to it and messages are being received ok. First problem is I can't remember which of my main 3 email accounts I used as the main account. Is it the first account. If not, is there a way of finding it in the Settings? The second problem, when I wanted to reoly to a message I posted yesterday I couldn't pass the password challenge. I thought I could simply change the password but it seems that could lead to losing some emails. https://support.mozilla.org/en-US/questions/1464891 This is the post I made yesterday under my original username but I can't sign today and had to set up a new account to make this post. In trying to sign in I was sent numerous codes, many of them did not work eventhough I copied then direct from the message. With an email address only, how can I access this Commun ity as I still have a question about the size on the TB 'dashboard. I wabt tio make almost everything bigger.
