For the last two weeks I have been experiencing problems with my email accounts in thunderbird.

Some default folders such as templates have disappeared I can't delete folders and subfolders that I have created It takes ages to migrate emails from one folder to another Gmail subfolders have disappeared apart from starred and important No option to 'Empty folder' any longer when you go to the trash so you have to delete each item or hightlight all and do a block delete. My sent box only has recently added sent items - not all in my gmail account I have uninstalled all my accounts from thunderbird the uninstalled Thunderbird three or four times now. Nothing has happened, but when I reinstalled this morning Templates was missing from my newly created email address I created a new folder in my account in thunderbird yesterday, but it has only synched and appeared on my ipad or iphone accounts this morning. Local folders account only has two things in it: Outbox and Deleted I am a real dinosaur with regard to techie issues and just don't know where to start to try and resolve the issues that I am experiencing. Has there been a recent update that has caused all these issues? I set up a new email account this morning thinking I would transfer everything from my existing email account to the new one and ditch my old email address, but both old and new accounts are missing Templates (which I use a lot) I have used Thunderbird for years and it is by the far the nicest email platform that I have ever used and I would like to continue with it as everything is so clear to see and sort. Can anyone help please?
