I want to switch back from the Thunderbird Release channel to the ESR channel but I do not understand the steps. Please help me with the exact, easiest steps. I am running Win 11.

I am looking to find a way to change the time in which I receive updates from Mozilla. Getting an update interferes with the operation of my laptop and to top it off, I don't know that there is an update coming through so I waste so much time thinking I have a problem with my connection, my router, my settings, my laptop. Hugely inconvenient. Why can't I set the time I want updates to come through and not interfere with me while my laptop is in use. This is enough to make me want to drop Firefox and switch out.

After updating my Thunderbird mail application from version 128 to 140, the shortcut icon for composing a message is no longer responsive and I cannot create a new message from it. I can no longer create a new message without right-clicking on a sent email and using “Edit as New Message (E)”. How can I get back to being able to create a message from the message creation shortcut?

Enough is enough—every update brings problems, crucial add-ons stop working, and now drag and drop attachments have stopped working. It's really inconvenient. Maybe it's time to stop this nonsense and implement paid subscriptions or purchases, but in a way that makes everything work.

Dear demons, when will you release a new update that will fix the old update? When will all the normal features be working? It's time to get back to real work for the benefit of society.

I have been using Thunderbird Mail for many years and have been satisfied with it. I followed the recommendation to upgrade to version 145. Then disaster struck: the previous version was completely deleted, including all email accounts and address books. How is that possible?

i dont want to update because of ai. i am tired of updates in the name of security that change how program works. i do not plan to update anymore. i do not want ai to know my name. i dont want to click it away every day. i am tired of your update popup. tired of clicking it away ten times a day. you want to synch to my contacts. dont know why' certainly dont want it to synch, dont even use my calander but you want it to synch also. why? i came to you for a browser. do you have a secure browser that is just a browser? can you help me stop the update popup or tell me a browser that is not ai.

My windows 10 PCs are running ver 140 (and say they are running the latest ver and no updates are available, but my W11 Pc is running v144. When I try and copy profile from 140 to 144 about 1/3rd of the directories are missing. I usually do to this prior to going on a trip when I copy from desktop pc running W10 to laptop with W11. Last time I did this there were no problems as both were running v140, but now that the laptop upgraded itself to ver144 that's no longer possible as a third of the directories end up missing - things like Inbox, Trash, Drafts, Archive etc which are fairly important. I've paused all Thunderbird updates until the problem is resolved. Can you help please?
