I have a list so long it won't fit here. I can only think to install back to an update 10 days ago. I can't find an option for that- and I am not a proffessional- just a simple user. I have a MacAir, since installing the latest update, Thunderbird: stalls for so long and can't switch it off or access anything for hours sporadically, it won't save 'sent' emails sporadically, it sends emails full of garbage - numbers, green and black screens, and other illegable content. sporadically. A lot of problems happen the moment I put an image into the content. and then I can't undo it. I can't access the image to move it, to delete it, just stuck. the signature keeps including code. it now says 105% full. Since when did we have a quota? I didn't know how to fix it. So it's now blocking me receiving emails. so I archived, deleted mails and it shifted it. BUT I have never had to do this before and don't want to -I have a busness to run and need to keep records. I can't delete in the future. What is this stupid quota thing? I can keep going with the problems I have. But I don't have copious amounts of weeks and months to now trouble shoot. So I thought I just take it back to a previous update -say 2 weeks ago before th eproblems started, and not update again until Thunderbird can function on the Mac. Can anyone help me? I am scared to uninstall, as I don't want to lose my contacts again. (had previous problems with Thunderbird in the last few months) ...now this. and have no idea how to get help? I want to be loyal to thunderbird- but I can't function with it right now. ....anyone?
